Opinion of the Court by MOON, C.J.

Plaintiffs-appellants Benjamin Pulawa, III (Pulawa) and Danelle Pulawa, individually and as Prochein Ami for Darcie Pulawa and Benjamin Pulawa, IV [hereinafter, collectively, the plaintiffs or the Pulawas], initiated the instant action for negligence arising out of an incident in which Pulawa, a construction superintendent, was seriously injured as a result of being struck in the head by a hardened bag of cement that was propelled into the air during the course of excavation work. The plaintiffs alleged that defendants-appellees E.E. Black, an excavation and duct line contractor, and GTE Hawaiian Tel (GTE), which had contracted with E.E. Black to conduct excavation and duct line work, were responsible for burying the cement bag approximately two to three years prior to the subject incident during the course of installing a telephone duct line in the same approximate area where Pulawa was overseeing excavation work in connection with a subsequent project.

The plaintiffs appeal from that portion of the Circuit Court of the First Circuit's May 25, 2004 final judgment entered pursuant to an order granting summary judgment in favor of E.E. Black and GTE. Essentially, the circuit court ruled that E.E. Black did not owe a legal duty of care to Pulawa. The plaintiffs also challenge that portion of the circuit court's order denying in part their motion to disallow costs.

For the reasons discussed below, we affirm the circuit court's May 25, 2004 final judgment.

I. BACKGROUND

A. Factual Background

The relevant facts of the instant case involve two separate construction projects in the Kaka'ako Improvement District in Honolulu, Hawai'i. The first project was conducted in 1993-1994 by E.E. Black. The second project was conducted in 1995-1996 by O'ahu Construction Company (OCC), during which Pulawa sustained his injuries.

1. The 1993-1994 Project (Conducted by E.E. Black)

Sometime in 1993, GTE hired E.E. Black to install underground telephone lines along Kamake'e Street in the Kaka'ako Improvement District [hereinafter, the underground duct line project]. E.E. Black was responsible for furnishing all of the materials and labor, as well as for performing all of the necessary work for the project. Although a GTE engineer served as an inspector for the project, GTE hired Engineers Surveyors Hawai'i (ESH) to also provide inspection work for the project.

The underground duct line project involved certain excavation and backfill work. According to GTE's "Standard Specifications for Placing Underground Telephone Lines," which "are intended to govern the work on all contracts awarded for placement of underground telephone systems by GTE . . . throughout the State of Hawai'i," "[a]ll wood and debris shall be removed from [the excavated] trench before backfilling[,]" and "[b]ackfill material shall be free of wood, paper or other objectionable material." The GTE inspector testified that the purpose of the foregoing requirements was to prevent "settlement and/or street failure." An E.E. Black foreman agreed that inappropriate backfill could lead to settlement and/or street failure. The ESH inspector also testified that improper backfill could potentially pose a danger to "equipment used by a future contractor" as well as to the safety of future contractors.

E.E. Black began excavation at the intersection of Kamake'e and Kona Streets on or about October 21, 1993. E.E. Black then backfilled the excavated area, using "select borrow" backfill material, on December 22, 1993. "Select borrow" is a type of backfill material, where the largest pieces of material used as backfill are no more than one inch in diameter.

During the underground duct line project, E.E. Black used "hand mixed" cement in order to make small repairs or patch existing sewer lines in the areas of construction. An ESH inspector witnessed E.E. Black mixing cement at the job site approximately ten times during the course of the project. E.E. Black's use of cement during the underground duct line project was acknowledged by an E.E. Black project engineer.

According to a "contract set of plans" that E.E. Black apparently utilized during its project, the fact that "there would be future underground work along Kamake'e Street" "[a]fter E.E. Black performed its work" was reflected on those plans. E.E. Black's project appeared to have concluded sometime in early 1994.

2. The 1995-1996 Project (Conducted by OCC)

Sometime in 1995, OCC began work on the installation of water and electrical lines, as well as widening roads and constructing new sidewalks and pavement in the Kaka'ako Improvement District. As part of the project, OCC was required to perform excavation work. On August 20, 1996, during the course of the excavation work, it appears that OCC encountered the GTE duct line that E.E. Black had previously installed. On that day, Pulawa, a construction superintendent employed by OCC, was overseeing the excavation work being performed by three other OCC employees at the intersection of Kamake'e and Kona Streets. One employee was operating a loader, the second was operating a backhoe, and the third employee was acting as a grade checker. The backhoe operator was excavating a trench and placing the excavated material somewhere near the trench. The loader operator would then pick up the material and deposit it in a dump truck. Because of the limited space in the excavation area, the loader operator would have to drive over the pile of excavated material in order to place the scooped-up material into the dump truck. The loader operator would then reverse back over the pile and repeat the process until the excavated material was removed.

While removing the excavated material as described above, the loader operator indicated that he heard a "whoosh" sound as he was reversing over the pile of excavated material and saw what appeared to be a "rock" being propelled from the left rear tire of the loader, striking Pulawa on the head. When the accident occurred, Pulawa was apparently standing approximately fifteen to twenty feet away from the loader. According to the loader operator, he later believed that the "rock" was "a half bag of concrete." Another OCC employee described the "rock" as having "pieces of cement bag embedded in it." During the discovery process, it was apparently revealed that the "rock" was "a 30-pound chunk of hardened cement" "in a cement bag with brown packaging and plastic wrapping." As a result of the accident, Pulawa sustained severe head injuries, including a depressed and open skull fracture.

B. Procedural History

On August 19, 1998, the plaintiffs filed a complaint against GTE, E.E. Black, and Morrison Knudsen Corporation/Walter SCI Construction (USA) (Morrison Knudsen). On April 12, 2000, the plaintiffs filed a first amended complaint, adding M. Sakuma Electrical, Inc. (Sakuma), a construction company, as a defendant and dismissing Morrison Knudsen as a defendant. The plaintiffs alleged that the "rock" that struck Pulawa was "a piece of cement [that] originated from a discarded bag of hardened cement which was left in the area [of the accident] or abandoned." The plaintiffs further alleged:

8. Defendants GTE, E.E. Black and/or [Sakuma] performed work in the area [of the accident] or project site prior to [OCC]. Said [d]efendants negligently failed to pick up, clean up or remove the cement bag after completion of their work or portion of work at the job site.

9. Said [d]efendants knew or should have known that the failure to remove a cement bag, or properly clean up the job site, would create a hazardous condition or threaten the safety of other workers on the job site, and therefore the [d]efendants had the duty to remove the cement bag after completion of their portion of work.

The first amended complaint set forth two counts against GTE, E.E. Black, and Sakuma: (1) negligence (Count I); and (2) loss of consortium (Count II). The loss of consortium claim was asserted by Danelle Pulawa on behalf of herself and the Pulawas' two minor children.

On April 5, 2001, Sakuma moved for summary judgment, contending that there was no evidence that the trench excavated by OCC was in the same location where Sakuma had conducted an excavation project sometime in 1994, two years prior to the subject accident. Specifically, Sakuma claimed that "its project area was across the street from the site where [Pulawa] was working and where the cement bag was apparently uncovered." (Emphasis omitted.) On May 8, 2001, the plaintiffs filed a statement of no opposition to Sakuma's motion for summary judgment. On May 9, 2001, E.E. Black and GTE filed their memorandum in opposition to Sakuma's motion for summary judgment. On May 30, 2001, the circuit court entered an order granting Sakuma's motion for summary judgment.

On March 10, 2004, GTE moved for summary judgment against the plaintiffs on the basis that "the undisputed facts in this case establish that it cannot be held liable to [the p]laintiffs for `negligently failing to pick up, clean up or remove the cement bag after completion of their work or portion of their work at the job site' as alleged in [the p]laintiffs' [f]irst [a]mended [c]omplaint." Specifically, GTE maintained that it "did not perform the excavation or backfill work for the earlier project, particularly in the area in question." Rather, GTE asserted that it "contracted with E.E. Black, an independent contractor, to perform duct line work, which involved certain excavation and backfilling work, in 1993."

On March 17, 2004, E.E. Black moved for summary judgment against the plaintiffs on the ground that "it did not owe a legal duty of care to [the p]laintiffs because it was not reasonably foreseeable that [Pulawa] would be injured or subject to an unreasonable risk of harm created by any alleged negligent conduct on the part of E.E. Black relating to the `large piece of cement' that `originated from a discarded bag of hardened cement'" E.E. Black maintained that "[t]here is no evidence on the basis of which a jury can conclude that E.E. Black knew or had reason to know of a dangerous condition relating to leaving or abandoning a `discarded bag of hardened cement' underground and that the condition created a foreseeable risk of harm to [Pulawa]." (Emphasis in original.)

On April 20, 2004, the circuit court held a hearing on, inter alia, GTE's and E.E. Black's motions for summary judgment. At the end of the hearing, the circuit court stated that it was persuaded by the arguments and authorities cited in GTE's and E.E. Black's motions for summary judgment and, thus, orally granted their motions for summary judgment. On May 12, 2004, the circuit court entered its written order granting GTE's and E.E. Black's motions for summary judgment. The circuit court also ruled that GTE's and E.E. Black's joint motion for summary judgment regarding spoliation of evidence was rendered moot by its order granting GTE's and E.E. Black's separate motions for summary judgment.

On May 25, 2004, final judgment was entered in favor of E.E. Black and GTE. On May 27, 2004, E.E. Black and GTE filed their notice of taxation of costs, requesting costs in the amount of $35,509.50, pursuant to Hawai'i Rules of Civil Procedure (HRCP) Rule 54(d) (2004) and Hawai'i Revised Statutes (HRS) § 607-9 (1993). On June 3, 2004, costs in the amount of $35,509.50 were taxed by the clerk of the circuit court against the plaintiffs. On June 16, 2004, the plaintiffs filed a motion to disallow costs, contending that it would be inequitable to award costs against the plaintiffs inasmuch as Pulawa remains unemployed and Danelle Pulawa's loss of consortium claim on behalf of herself and the Pulawas' two minor children are merely derivative. The plaintiffs also challenged several entries made by E.E. Black and GTE in their notice of taxation of costs.

At a hearing held on July 27, 2004, the circuit court orally granted in part and denied in part the plaintiffs' motion to disallow costs and entered its written order on August 6, 2004. Specifically, the circuit court denied costs in the amount of $45.95 attributed to meals and granted costs in the amount of $35,463.55. On August 31, 2004, an amended judgment was entered in favor of E.E. Black and GTE, incorporating the circuit court's August 6, 2004 order. On September 7, 2004, the plaintiffs filed their amended notice of appeal.

II. STANDARDS OF REVIEW

A. Motion for Summary Judgment

This court reviews the circuit court's grant of summary judgment de novo. O'ahu Transit Servs., Inc. v. Northfield Ins. Co., 107 Hawai'i 231, 234, 112 P.3d 717, 720 (2005) (citing Hawai'i Cmty. Fed. Credit Union v. Keka, 94 Hawai'i 213, 221, 11 P.3d 1, 9 (2000)). The standard for granting a motion for summary judgment is well settled:

[S]ummary judgment is appropriate if the pleadings, depositions, answers to interrogatories, and admissions on file, together with the affidavits, if any, show that there is no genuine issue as to any material fact and that the moving party is entitled to judgment as a matter of law. A fact is material if proof of that fact would have the effect of establishing or refuting one of the essential elements of a cause of action or defense asserted by the parties. The evidence must be viewed in the light most favorable to the non-moving party. In other words, we must view all of the evidence and the inferences drawn therefrom in the light most favorable to the party opposing the motion.

Price v. AIG Hawai'i Ins. Co., 107 Hawai'i 106, 110, 111 P.3d 1, 5 (citation omitted) (brackets in original), reconsideration denied, 107 Hawai'i 106, 111 P.3d 1 (2005).

B. Duty of Care

"This court addresses whether a defendant owes a duty of care to a particular plaintiff as a question of law under the right/wrong standard." Blair v. Ing, 95 Hawai'i 247, 253, 21 P.3d 452, 458 (2001) (citation omitted).

C. Taxation of Costs

"The award of a taxable cost is within the discretion of the [circuit] court and will not be disturbed absent a clear abuse of discretion." Wong v. Takeuchi, 88 Hawai'i 46, 52, 961 P.2d 611, 617 (1998) (internal quotation marks and citation omitted). "An abuse of discretion occurs when the [circuit] court has clearly exceeded the bounds of reason or disregarded rules or principles of law or practice to the substantial detriment of a party litigant." Hac v. Univ. of Hawai'i, 102 Hawai'i 92, 101, 73 P.3d 46, 55 (2003) (internal quotation marks and citations omitted).

III. DISCUSSION

On appeal, the plaintiffs challenge the circuit court's order granting summary judgment in favor of E.E. Black and GTE and the order denying in part the plaintiffs' motion to disallow costs. Each of the plaintiffs' contentions will be discussed in turn.

A. E.E. Black's Motion for Summary Judgment

The plaintiffs contend that the circuit court erred in granting summary judgment in favor of E.E. Black because it failed to recognize that E.E. Black

had a duty to protect against "foreseeable dangers," engaged in negligence notwithstanding the fact that it knew that the "foreseeable range of danger" extended to the public and future contractors, and the "risks or hazards" whose likelihood made the conduct "unreasonably dangerous" included the specific sequence of events that led to . . . Pulawa's severe head injuries.

The plaintiffs further argue that the circuit court "failed to consider the material and competent evidence that had been presented and which showed that E.E. Black owed a legal duty to . . . Pulawa under the facts and circumstances of this case." The plaintiffs primarily rely on the testimony of Alan Los Banos, Jr., the plaintiffs' construction safety expert, who generally testified in his affidavit and deposition that "burial of objects such as a bag of cement, in lieu of proper fill, creates a risk that a future contractor's heavy construction vehicles or equipment would strike or rollover the object and project it through the air with great force." Thus, the plaintiffs maintain that Los Banos' expert testimony "alone, at the minimum, created a genuine issue of fact, which precluded summary judgment."

Preliminarily, E.E. Black contends that the plaintiffs confuse the "foreseeability" issue "by citing and referencing `foreseeability' in the context of a breach of a legal duty and/or causation instead of the context of whether there is a legal duty in the first instance." (Emphases omitted.) Consistent with its assertion that "[f]oreseeability, in the context of a legal duty, is a question of law[,]" E.E. Black argues that "Los Banos' opinions regarding the issue of foreseeability within the context of whether E.E. Black had a legal duty of care owed to [the p]laintiffs should be disregarded, per prevailing case law as they cannot be used or considered to establish a legal duty of care." E.E. Black maintains that it owed no legal duty to the plaintiffs because

the foreseeable danger or harm related to use of improper backfill for roads pertains to settlement of the road and its failure related to those traveling on or using the road. Voids, settlement, and street failure that possibly could endanger people using and driving on the street are the foreseeable dangers if improper backfill such as a bag of cement is used. The risk or hazard is not that the fill material will be dug up, run over by a vehicle, and projected into the air by the tire of the vehicle. It is a generous stretch of the imagination to conclude as a matter of law that the risk or hazard that fill material will be dug up, run over by a vehicle, and projected into the air by the tire of that vehicle is the likely or probable result of the alleged conduct.

1. Foreseeability in the Context of Duty

"[I]t is fundamental that a negligence action lies only where there is a duty owed by the defendant to the plaintiff." Bidar v. Amfac, Inc., 66 Haw. 547, 551-52, 669 P.2d 154, 159 (1983) (citations omitted).

The existence of a duty owed by the defendant to the plaintiff, that is, whether . . . such a relation exists between the parties that the community will impose a legal obligation upon one for the benefit of the other — or, more simply, whether the interest of the plaintiff which has suffered invasion was entitled legal protection at the hands of the defendant, is entirely a question of law.

Knodle v. Waikiki Gateway Hotel, Inc., 69 Haw. 376, 385, 742 P.2d 377, 383 (1987) (internal quotation marks and citations omitted) (ellipsis in original). Regarding the imposition of a duty of care, this court has stated that, generally,

[i]n considering whether to impose a duty of reasonable care on a defendant, we recognize that duty is not sacrosanct in itself, but only an expression of the sum total of those considerations of policy which lead the law to say that the particular plaintiff is entitled to protection. Legal duties are not discoverable facts of nature, but merely conclusory expressions that, in cases of a particular type, liability should be imposed for damage done. In determining whether or not a duty is owed, we must weigh the considerations of policy which favor the [plaintiff's] recovery against those which favor limiting the [defendant's] liability. The question of whether one owes a duty to another must be decided on a case-by-case basis.

Blair, 95 Hawai'i at 259-60, 21 P.3d at 464-65 (citations omitted) (format altered). In addition to the aforementioned principles, this court has also regarded several factors in determining whether to impose a duty:

[W]hether a special relationship exists, the foreseeability of harm to the injured party, the degree of certainty that the injured party suffered injury, the closeness of the connection between the defendants' conduct and the injury suffered, the moral blame attached to the defendants, the policy of preventing harm, the extent of the burden to the defendants and consequences to the community of imposing a duty to exercise care with resulting liability for breach, and the availability, cost, and prevalence of insurance for the risk involved.

Id. at 260, 21 P.3d at 465 (ellipsis and citation omitted) (format altered).

Regardless of the source of a particular duty, [however,] a defendant's liability for failing to adhere to the requisite standard of care is limited by the pr[o]position that the defendant's obligation to refrain from particular conduct [or, as the circumstances may warrant, to take whatever affirmative steps are reasonable to protect another] is owed only to those who are foreseeably endangered by the conduct and only with respect to those risks or hazards whose likelihood made the conduct [or omission] unreasonably dangerous. Thus, if it is not reasonably foreseeable that the particular plaintiff will be injured if the expected harm in fact occurs, the defendant does not owe that plaintiff a duty reasonably to prevent the expected harm.

Doe Parents No. 1 v. State Dep't of Educ., 100 Hawai'i 34, 72, 58 P.3d 545, 583 (2002) (internal quotation marks and citations omitted) (first set of brackets and bold emphases added); see also Janssen v. Am. Hawai'i Cruises, Inc., 69 Haw. 31, 34, 731 P.2d 163, 166 (1987) (stating that "a defendant owes a duty of care only to those who are foreseeably endangered by the conduct and only with respect to those risks or hazards whose likelihood made the conduct unreasonably dangerous") (internal quotation marks and citations omitted); Hulsman v. Hemmeter Dev. Corp., 65 Haw. 58, 68, 647 P.2d 713, 720 (1982) (same).

The test of foreseeability "is whether there is some probability of harm sufficiently serious that a reasonable and prudent person would take precautions to avoid it." Knodle, 69 Haw. at 388, 742 P.2d at 385 (internal quotation marks, brackets, and citations omitted). "It does not mean foreseeability of any harm whatsoever, and it is not sufficient that injury is merely possible." Henderson v. Prof'l Coatings Corp., 72 Haw. 387, 396, 819 P.2d 84, 90 (1991) (quoting 65 C.J.S. Negligence § 5(5) (1966)) (internal quotation marks omitted); see also Lee v. Corregedore, 83 Hawai'i 154, 167, 925 P.2d 324, 337 (1996) ("[T]here are clear judicial days on which a court can foresee forever and thus determine liability but none on which that foresight alone provides a socially and judicially acceptable limit on recovery of damages for that injury." (Internal quotation marks and citation omitted.)).

"[T]he concept of `duty[,]' [however,] involves more than mere foreseeability of harm." Taylor-Rice v. State, 91 Hawai'i 60, 71-72, 979 P.2d 1086, 1097-98 (1999).

[A] court's task — in determining "duty" — is not to decide [merely] whether a particular plaintiff's injury was reasonably foreseeable in light of a particular defendant's conduct, but rather to evaluate more generally whether the category of negligent conduct at issue is sufficiently likely to result in the kind of harm experienced that liability may appropriately be imposed on the negligent party.

Id. at 72, 979 P.2d at 1098 (citing Thing v. La Chusa, 48 Cal.3d 644, 257 Cal.Rptr. 865, 771 P.2d 814, 819 n. 3. (1989)) (internal quotation marks and citation omitted).

2. Foreseeability in the Context of Duty: Question of Law versus Question of Fact

On appeal and at the circuit court level, the parties dispute whether foreseeability is an issue of fact for the trier of fact to decide or is an issue of law for the court to determine. The plaintiffs maintain that "[r]easonable foreseeability is the very prototype of a question that must be left to a jury." (Citation omitted.) On the other hand, E.E. Black maintains that foreseeability in the context of duty is an issue of law for the court to determine.

This court has previously noted that, in the context of determining the existence and scope of a duty, foreseeability is a question of law for the court to resolve. See Bidar, 66 Haw. at 553 n. 3, 669 P.2d at 159 n. 3 (noting that foreseeability may "play an important role in the definition of duty and the delineation of its scope by the court") (citing Hulsman, 65 Haw. at 68, 647 P.2d at 720-21 (duty owed only to those foreseeably endangered; foreseeability is a question of law); Ajirogi v. State, 59 Haw. 515, 527, 583 P.2d 980, 988 (1978) (foreseeability of risk of harm to plaintiff is a question of law when determining whether plaintiff is among those to whom defendant's duty of care extends); Kelley v. Kokua Sales Supply, Ltd., 56 Haw. 204, 209, 532 P.2d 673, 676 (1975) (as a matter of law, duty not owed to one to whom defendants could not reasonably foresee consequences)). Indeed, other jurisdictions have also recognized that foreseeability, in the context of determining the existence and scope of a duty, is a question of law for the court to determine. See Ballard v. Uribe, 41 Cal.3d 564, 224 Cal.Rptr. 664, 715 P.2d 624, 629 n. 6 (1986); Knoll v. Bd. of Regents of the Univ. of Neb., 258 Neb. 1, 601 N.W.2d 757, 762-63 (1999); Clohesy v. Food Circus Supermarkets, Inc., 149 N.J., 496 694 A.2d 1017, 1020-21 (1997).

Foreseeability, however, in the context of breach of duty and causation is a question of fact for the trier of fact to resolve. See Bidar, 66 Haw. at 552-53, 669 P.2d at 159-60. "[T]he distinction between foreseeability as it applies to duty and as it applies to proximate cause is a critical distinction that is too often and too easily overlooked." Knoll, 601 N.W.2d at 763.

Foreseeability as it impacts duty determinations refers to the knowledge of the risk of injury to be apprehended. The risk reasonably to be perceived defines the duty to be obeyed; it is the risk reasonably within the range of apprehension, of injury to another person, that is taken into account in determining the existence of the duty to exercise care[.]

Foreseeability that affects proximate cause, on the other hand, relates to the question of whether the specific act or omission of the defendant was such that the ultimate injury to the plaintiff reasonably flowed from defendant's breach of duty. Foreseeability in the proximate cause context relates to remoteness rather than existence of a duty.

Clohesy, 694 A.2d at 1021 (internal quotation marks and citations omitted) (emphasis added); see also Knoll, 601 N.W.2d at 763; Atl. Mut. Ins. Co. v. Kenney, 323 Md. 116, 591 A.2d 507, 515 (1991) ("Foreseeability as a factor in the determination of the existence of a duty involves a prospective consideration of the facts existing at the time of the negligent conduct. Foreseeability as an element of proximate cause permits a retrospective consideration of the total facts of the occurrence[.]" (Citation omitted.) (Emphases added.)).

Here, the plaintiffs have "overlooked" "[t]he distinction between foreseeability as it applies to duty and as it applies to proximate cause." Knoll, 601 N.W.2d at 763. For example, the plaintiffs maintain that "[t]he precise manner of the injury or the specific harm or consequence of the negligence need not be foreseeable." However, as E.E. Black points out, "[t]he cases cited by [the p]laintiffs all involve factual analysis relating to foreseeability in the context of causation," not foreseeability in the context of duty. See Rogers ex rel. Standley v. Retrum, 170 Ariz. 399, 825 P.2d 20, 22 (Ct.App. 1991) (stating that "the particular manner in which the injury is brought about need not be foreseeable" in the context of "legal cause"); Tieder v. Little, 502 So.2d 923, 927 (Fla.Dist.Ct.App. 1987) (stating that the "foreseeability aspect of the proximate cause element is . . . satisfied in this case" because "[t]he collapse of a brick wall resulting in the death of a person near such wall is plainly a reasonably foreseeable consequence of negligently designing and constructing such a wall without adequate supports in violation of applicable building codes"); Christopher v. Father's Huddle Café, Inc., 57 Mass.App.Ct. 217, 782 N.E.2d 517, 526 (2003) (stating that, in the context of causation, "[t]he specific kind of harm need not be foreseeable as long as it was foreseeable that there would be harm from the act which constituted the negligence"). Consequently, to the extent the plaintiffs rely on their cited cases for the proposition that "[t]he precise manner of the injury or the specific harm or consequence of the negligence need not be foreseeable," we disregard them as not germane to the issues presented in the instant appeal. Inasmuch as the issue of foreseeability in the context of duty is a question of law for the court to resolve, the court, not the trier of fact, must determine the existence and scope of duty, if any, owed by E.E. Black to the plaintiffs.

3. Duty in the Context of this Case

As previously stated, the plaintiffs rely on Los Banos' expert opinion to establish the fact that "[t]he risk of a buried cement bag becoming a projectile was . . . clearly foreseeable and not `highly extraordinary.'" Specifically, Los Banos' affidavit provides in relevant part:

2. I am employed as a Safety Coordinator and Program Specialist for the AFL-CIO, Plasterers Cement Masons, Local 630, and Bricklayers Allied Craft-workers, Local 1.

3. I am a safety specialist who investigates construction accidents. I have been so employed over the past nine years, and have worked in the construction field since 1979. My background and experience includes various forms of training in construction and construction safety and OSHA-approved classes. . . .

. . . .

8. In my opinion, it is improper for a contractor to bury objects not consistent with the job specifications as fill materials, such as this object buried under a public roadway such as Kamake'e Street. Such practices have resulted in materials being buried that could pose hazards to future construction workers.

9. The dangers of engaging in such practices would include the risk of heavy construction equipment or vehicles striking or rolling over materials such has [sic] hardened cement so as to project them through the air with great force, jeopardizing the lives and safety of workers and other persons in the immediate area.

On appeal, the plaintiffs argue that Los Banos' "expert testimony established, at least for summary judgment purposes," that:

Burial of objects such as a bag of cement, in lieu of proper fill, creates a risk that a future contractor's heavy construction vehicles or equipment would strike or rollover the object and project it through the air with great force.

Doing so "has the potential for being a projectile that can basically fly."

Heavy construction equipment and "the amount of pressure . . . can launch" such objects.

"Chunks will fly . . . from the tires, if it spins."

"[W]hen you're on a hard surface and you have a rubberized thing that's pressing down, something has to give. The weak area can be rocks that fly."

"When wheels spin, . . . we see things fly from the tires. Especially in the back, when it spins, the traction, as they're moving, you see it picks up sometimes in the grooves of the tires and just launches itself."

In Hawai'i, construction workers know that such objects can be propelled through the air.

Construction safety training classes are conducted which cover the danger of flying construction debris caused by improper materials that are abandoned or left at a job site.

Indeed, similar incidents have occurred at construction worksites in Hawai'i.

. . . Los Banos has personally seen large rocks fly out from under heavy equipment at construction sites.

A flying object "jeopardizes the lives and safety of workers."

The frequency with which this happens depends on the type of equipment being operated, the speed at which it is being operated, and the type of materials in the vicinity.

E.E. Black, however, maintains that Los Banos' opinions are inadmissible inasmuch as they cannot be used or considered to establish a legal duty of care. In response, the plaintiffs assert that

legal duty must be examined in light of its factual context, not in a vacuum. Mr. Los Banos provided facts relevant to the court's legal duty analysis, and these facts establish some probability of harm sufficiently serious that a reasonable and prudent person (e.g. contractor) would have taken precautions to avoid it.

Generally, "[t]he testimony of expert witnesses is . . . confined to matters of fact, as distinguished from matters of law." Create 21 Chuo, Inc. v. Southwest Slopes, Inc., 81 Hawai'i 512, 522 n. 4, 918 P.2d 1168, 1178 n. 4 (App. 1996). In other words, an "expert or nonexpert opinion that amounts to a conclusion of law cannot be properly received in evidence, since the determination of such questions is exclusively within the province of the court." Id. (citation omitted). Nevertheless, in the context of duty, "expert testimony might be relevant to help establish some underlying fact on which duty may ultimately rest[.]" Parra v. Bldg. Erection Servs., 982 S.W.2d 278, 284 (Mo.Ct.App. 1998); see also Peck v. Horrocks Eng'rs, Inc., 106 F.3d 949, 952 (10th Cir.1997) ("Whether a duty of care exists is a question of law, although expert testimony may be helpful on the issue." (Citations omitted.)).

Contrary to the plaintiffs' position, however, Los Banos did not "provide facts relevant to the court's legal duty analysis" in the instant case. (Emphasis added.) A closer examination of Los Banos' deposition testimony reveals that the basis for the "fact" that "[t]he risk of a buried cement bag becoming a projectile was . . . clearly foreseeable and not `highly extraordinary'" was Los Banos' prior observations of nine-inch rocks traveling "maybe about five feet, six feet away." Specifically, Los Banos testified:

Q: [By defense counsel] How big was the biggest rock that you've seen fly like that.

[PLAINTIFFS' COUNSEL]: Like that?

[DEFENSE COUNSEL]: Well, when a loader or piece of equipment goes over it and then shoots it out.

[LOS BANOS]: About — I've seen rocks about, roughly, this big fly out of there.

Q: (By [defense counsel]): When you say "this big" —

A: [By Los Banos] Roughly, what, about nine inches. Around there.

Q: Nine inches, around?

A: Yeah.

Q: How far did it fly?

A: Usually, it doesn't fly that far. It just flies maybe about five feet, six feet away.

(Emphasis added.) However, in the present case, the cement "rock" that was propelled into the air weighed approximately thirty pounds and traveled at least fifteen to twenty-five feet before striking Pulawa in the head. When apprised of these facts, Los Banos testified:

Q: [By defense counsel] Was this accident, then, unusual?

A: [By Los Banos] My opinion — Well, I feel it's unusual. Especially the launching that far. I thought it was, like, wow, this is different.

Q: Going over 20 feet and the thing[, i.e., the concrete "rock"] is, what, 20, 30 pounds —

A: At least, uh-huh.

Q: Unusual accident?

A: That's a big chunk flying there. Because, usually, when you run over it, it doesn't fly that far. It just kind of just-Five, six feet. When it launches that far, it's, like, wow, you know, what is that?

(Emphases added.) Thus, inasmuch as "[t]he opinion of an expert must pertain to the facts of the particular case[,]" Tortes v. King County, 119 Wash.App. 1, 84 P.3d 252, 258 (2003), and Los Banos' opinion does not, his opinion as to the "fact" that "[t]he risk of a buried cement bag becoming a projectile was . . . clearly foreseeable and not `highly extraordinary'" is not helpful to this court's "legal duty analysis." See Nebraska Plastics, Inc. v. Holland Colors Ams., Inc., 408 F.3d 410, 416 (8th Cir.2005) (stating that "[a]n expert opinion that fails to consider the relevant facts of the case is fundamentally unsupported" and, therefore, "must be excluded"). Accordingly, we next turn to the dispositive issue in this case, that is, whether E.E. Black owed a legal duty of care to Pulawa.

Other jurisdictions have recognized that "a contractor has a duty to maintain the premises on which it performs work in a reasonably safe condition for persons who the contractor may reasonably expect to come onto the site." Raimo v. Fischer, 372 N.J.Super. 448, 859 A.2d 709, 712 (App.Div. 2004) (citation omitted); see also Chance v. Lawry's, Inc., 58 Cal.2d 368, 24 Cal.Rptr. 209, 374 P.2d 185, 190 (1962) (stating that an independent contractor's duty of care is "a general duty imposed by law to use reasonable care to prevent damage to persons whem [sic] he may reasonably expect to be affected by his work") (internal quotation marks and citation omitted). In other words, a contractor generally

has a duty to use reasonable care both in his or her work and in the course of performance of the work[; h]owever, the duty of reasonable care is not, of course, owed to the world at large, but rather to those who might reasonably be foreseen as being subject to injury by the breach of the duty.

Peters v. Forster, 804 N.E.2d 736, 743 (Ind. 2004) (internal quotation marks, brackets, and citations omitted). Indeed, as previously discussed, this court has held that "the defendant's obligation to refrain from particular conduct . . . is owed only to those who are foreseeably endangered by the conduct and only with respect to those risks or hazards whose likelihood made the conduct . . . unreasonably dangerous." Doe Parents No. 1, 100 Hawai'i at 72, 58 P.3d at 583 (emphasis added); see also Janssen, 69 Haw. at 34, 731 P.2d at 166. Moreover, "in determining the scope of the defendant's duty, the focus is on the defendant's viewpoint, that is, whether the defendant could reasonably foresee the plaintiff's injury." Yager v. Illinois Bell Tel. Co., 281 Ill.App.3d 903, 217 Ill.Dec. 695, 667 N.E.2d 1088, 1092 (1996) (citations omitted) (emphasis in original).

Here, Pulawa was standing approximately fifteen to twenty feet away from the excavation area that was located in the same vicinity of an excavation site of a prior construction project that was backfilled by E.E. Black two years earlier. Although E.E. Black "has a duty to use reasonable care in both [its] work and in the course of performance of the work[,]" it cannot be said that Pulawa was foreseeably endangered by E.E. Black's conduct such that the cement bag it allegedly failed to remove would be propelled in the air by the tire of a loader and strike Pulawa in the head. The plaintiffs adduced testimony from several GTE inspectors and engineers, as well as an E.E. Black project engineer, who purportedly oversaw the 1993-1994 underground duct line project. The testimony focused on the risks or hazards created by E.E. Black's alleged failures to remove the cement bag and to comply with contract specifications regarding proper backfill requirements. The risk or hazard that was consistently identified focused on the possibility of settlement of the road and street failure. In fact, the plaintiffs, in their memorandum in opposition to E.E. Black's motion for summary judgment, posited that "[a]ppropriate backfill is necessary to assure `the integrity of the pavement structure,' while inappropriate fill can promote voids or settlement and allow for failure of the roadway." (Citation omitted.) The plaintiffs also argued that "[u]se of improper fill by [E.E. Black] under a public roadway such as Kamake'e Street could lead to settlement and road failure." (Citations omitted.) The GTE inspector who oversaw the underground duct line project in 1993-1994 testified that compliance with contract specifications regarding proper backfill requirements is to prevent "settlement and/or street failure." Indeed, the plaintiffs' own expert, Los Banos, confirmed that the purpose of job specifications relating to proper backfill requirements is to promote "uniform compaction," which, in turn, prevents "voids." Moreover, Los Banos testified that the purpose of such job specifications is not to prevent the possibility of non-conforming backfill material being unearthed and projected into the air, striking somebody:

Q: [By defense counsel] So the purpose for designating specifically the size of backfill materials is so that there is proper compaction?

A: [By Los Banos] Uniform compaction.

Q: The purpose for those specifications are not so that it does impose a danger to others, right?

A: What do you mean? For the size, you mean?

Q: Yes.

A: Yeah. No.

Q: That has nothing to do with, well, you know, if you leave rocks about five, 10 inches in there[, i.e., in the trench,] and if somebody digs it out it might hit somebody?

A: No. It's just engineering standards. You know, you're talking about dynamics.

(Emphases added.)

Although the plaintiffs adduced some testimony that improper backfill could potentially pose a danger to the safety of future contractors and that E.E. Black was generally aware that there would be future underground work along Kamake'e Street, such evidence does not meet the test of foreseeability, to wit, "whether there is some probability of harm sufficiently serious that a reasonable and prudent person would take precautions to avoid it." Knodle, 69 Haw. at 388, 742 P.2d at 385 (internal quotation marks, brackets, and citations omitted) (emphasis added). The aforementioned test "does not mean foreseeability of any harm whatsoever, and it is not sufficient that injury is merely possible." Henderson, 72 Haw. at 396, 819 P.2d at 90 (internal quotation marks and citation omitted) (emphasis added); see Ethyl Corp. v. Johnson, 345 Ark. 476, 49 S.W.3d 644, 648 (2001) (recognizing that "there is no duty to guard against merely possible, as opposed to likely or probable, harm"). Based on the evidence in the record, it appears that, although Pulawa did indeed suffer harm, such harm, though unfortunate, was "merely possible" and not "likely or probable" under the circumstances of this case.

Furthermore, the authorities relied upon by the plaintiffs regarding contractors all involve the type of foreseeable harm related to excavation and resurfacing work, that is, settlement, street failure, and holes. See Brent v. Unicol, Inc., 969 P.2d 627, 628 (Alaska 1998) (subsequent construction worker fell into a hole between an excavation wall and a rig mat left by a prior contractor); McMahon v. Richard Gorazd, Inc., 135 Ill. App.3d 211, 89 Ill.Dec. 944, 481 N.E.2d 787, 791-93 (1985) (painter fell from scaffold after ground under scaffold caved in where utility had earlier installed underground gas line; utility was under a duty to prevent or correct subsidence at the site of its excavations and could discharge such duty by, inter alia, "filling in any subsidence caused by the expected settling of the earth after such an excavation") (emphasis added); Hankins v. Elro Corp., 149 Mich.App. 22, 386 N.W.2d 163, 164 (1986) (per curiam) (bicycle on which plaintiff was riding struck a gap between two pieces of cement); Kapalczynski v. Globe Constr. Co., 19 Mich.App. 396, 172 N.W.2d 852, 852-53 (1969) (plaintiff fell into a hole in a street that defendant had resurfaced). The plaintiffs' two remaining cases dealt with foreseeable harm relating to the improper installation of furniture and containers. See Chance, 24 Cal.Rptr. 209, 374 P.2d at 187 (diner fell into open planter box installed in a narrow foyer of a busy restaurant); Raimo, 859 A.2d at 711 (plaintiff descending temporary staircase injured when staircase fell away from a house). Thus, the evidence adduced below, coupled with the arguments of the parties, clearly established that the risk or hazard of the buried cement bag being propelled into the air during a future excavation was not what made the failures to remove the cement bag and to comply with the contract specifications by E.E. Black unreasonably dangerous. In other words, E.E. Black's general duty to use reasonable care did not include within its scope the protection of Pulawa from the particular risk that he encountered. See Selwyn v. Ward, 879 A.2d 882, 883, 887-89 (R.I. 2005) (holding that harm resulting from a minor igniting a bottle of grain alcohol for sport was not a foreseeable consequence of selling alcohol to a minor; rather, foreseeable consequence would have been injuries resulting from minor's consumption of illegally obtained alcohol). Consequently, based on the state of the record, it cannot be said that E.E. Black owed a legal duty to the plaintiffs. Accordingly, we hold that the circuit court did not err in granting summary judgment in favor of E.E. Black.

B. GTE's Motion for Summary Judgment

The plaintiffs contend that the circuit court erred in granting summary judgment in favor of GTE because GTE is liable for (1) E.E. Black's acts and omissions and (2) its own acts and omissions. Specifically, the plaintiffs assert that "the evidence shows that GTE established sufficient control over E.E. Black to render GTE liable for the acts and omissions of E.E. Black" inasmuch as "GTE had an employee on the job site daily overseeing the progress of the construction[.]" Although not entirely clear from their opening brief, it appears from their reply brief that the plaintiffs allege that GTE is liable for its own acts and omissions based on negligent supervision of E.E. Black.

Inasmuch as E.E. Black did not owe a legal duty to the plaintiffs, it follows that GTE likewise would not be liable to the plaintiffs for E.E. Black's alleged acts and/or omissions in "fail[ing] to pick up, clean up or remove the cement bag after completion of their work or portion of work at the job site." Moreover, because "negligent supervision may only be found where an employee is acting outside of the scope of his or her employment," Dairy Road Partners v. Island Ins. Co., 92 Hawai'i 398, 427, 992 P.2d 93, 122 (emphasis in original), reconsideration denied, 92 Hawai'i 398, 992 P.2d 93 (2000), and the plaintiffs do not allege that E.E. Black was acting outside the scope of its alleged employment with GTE, the plaintiffs' complaint cannot be said to state a claim for negligent supervision. Accordingly, we hold that the circuit court did not err in granting summary judgment in favor of GTE.

C. Taxation of Costs

Lastly, the plaintiffs assert that the circuit court abused its discretion by denying in part their motion to disallow costs because: (1) the circuit court's award of summary judgment in favor of E.E. Black and GTE was erroneous; (2) it was inequitable to award costs in light of Pulawa's unemployment and limited means; and (3) joint and several liability for costs should not be imposed against Danelle Pulawa and the Pulawas' two minor children in light of the fact that their claims are derivative. E.E. Black and GTE, on the other hand, contend that HRCP Rule 54(d) creates a "strong presumption" that the prevailing party will recover costs, and "[a]ctual indigency, not merely limited financial resources, must be demonstrated." Inasmuch as Pulawa "receives Social Security benefits (approximately $1,500 per month), benefits from the Operating Engineers Trust Funds, and workers' compensation benefits," E.E. Black and GTE claim that the plaintiffs have not shown that they were incapable of paying the costs awarded to E.E. Black and GTE. Moreover, E.E. Black and GTE contend that HRCP Rule 54(d) "does not distinguish between derivative and non-derivative claims[,]" and, thus, costs were properly awarded against all the plaintiffs.

As previously stated, E.E. Black and GTE filed their notice of taxation of costs pursuant to HRCP Rule 54(d) and HRS § 607-9. HRCP Rule 54(d) provides that, "[e]xcept when express provision therefor is made either in a statute or in these rules, costs shall be allowed as of course to the prevailing party unless the court otherwise directs[.]" (Emphasis added.) HRCP Rule 54(d)

creates a strong presumption that the prevailing party will recover costs. . . . The presumption that the prevailing party is entitled to costs must be overcome by some showing that an award would be inequitable under the circumstances. The losing party bears the burden of making this showing.

Wong v. Takeuchi, 88 Hawai'i 46, 52, 961 P.2d 611, 617 (1998) (quoting 10 Moore's Fed. Prac. § 54.101(1)(a-b) (3d ed.1998)) (emphasis added). HRS § 607-9 provides that:

No other costs of court shall be charged in any court in addition to those prescribed in this chapter in any suit, action, or other proceeding, except as otherwise provided by law.

All actual disbursements, including but not limited to, intrastate travel expenses for witnesses and counsel, expenses for deposition transcript originals and copies, and other incidental expenses, including copying costs, intrastate long distance telephone charges, and postage, sworn to by an attorney or a party, and deemed reasonable by the court, may be allowed in taxation of costs. In determining whether and what costs should be taxed, the court may consider the equities of the situation.

(Emphasis added.)

Several courts of appeals have held that indigency, or modest means, is a factor that a district court may consider in awarding costs [pursuant to Federal Rules of Civil Procedure (FRCP) Rule 54(d). See, e.g., Cherry v. Champion Int'l Corp., 186 F.3d 442, 447 (4th Cir.1999) (evaluating whether a non-indigent losing plaintiff had the "effective ability to satisfy [the defendant's] bill of costs" or was "of such modest means that it would be unjust or inequitable to enforce [FRCP] Rule 54(d)(1) against her"); Weeks v. Samsung Heavy Indus. Co., Ltd., 126 F.3d 926, 945 (7th Cir.1997) ("[T]he losing party's inability to pay will suffice to justify denying costs."). Other courts that have adopted this approach also caution that a losing party's indigency or an inability to pay costs does not automatically mean that a costs award levied against that party is inequitable. See, e.g., Weaver v. Toombs, 948 F.2d 1004, 1008 (6th Cir.1991)[, superseded by statute as stated in In re Prison Litigation Reform Act, 105 F.3d 1131 (6th Cir.1997)] (holding that indigency may be a shield to imposition of costs, but that it is not an absolute shield). This case-by-case approach to the "indigency" factor has also been expressly or implicitly endorsed by noted commentators on the subject. See, e.g., 10 Moore's [Fed. Prac.] §§ 54.101[1][b], at 54-153, 54.104[1][a]-[c], at 54-198 to 54-201 [(3d ed.1999)]; 10 Wright[, Miller Kane, Fed. Prac. Procedure] § 2673, at 305-09 [(3d ed.1998)].

In re Paoli R.R. Yard PCB Litig., 221 F.3d 449, 463 (3d Cir.2000) (emphasis in original); see also Whitfield v. Scully, 241 F.3d 264, 270 (2d Cir.2001) (stating that, "[a]s a general matter[,] a district court may deny costs on account of a losing party's indigency, but indigency per se does not automatically preclude an award of costs"); Chapman v. AI Transp., 229 F.3d 1012, 1039 (11th Cir.2000) (en banc) (holding that "a non-prevailing party's financial status is a factor that a district court may, but need not, consider in its award of costs pursuant to [FRCP] Rule 54(d)"). In In re Paoli the United States Court of Appeals for the Third Circuit (Third Circuit) held that, "if a losing party is indigent or unable to pay the full measure of costs, a district court may, but need not automatically, exempt the losing party from paying costs." 221 F.3d at 464 (emphases in original). In so holding, the Third Circuit stated:

Such an approach is somewhat at odds with the traditional rule at law that the prevailing party was automatically entitled to its costs, but it is consistent with the rule at equity that the district court exercise its discretion to insure that the award be equitable. Allowing for the indigency factor in certain cases is also in keeping with the American tradition of not providing total reimbursement. . . . [T]he types of costs recoverable under [FRCP] Rule 54(d)(1) are quite circumscribed. These costs do not include such litigation expenses as attorney's fees and expert witness fees in excess of the standard daily witness fee, and as a result, while a prevailing party is awarded its [FRCP] Rule 54(d)(1) costs, those costs often fall well short of the party's actual litigation expenses[.]

Id. (internal quotation marks and citations omitted). Nevertheless,

[i]f a district court[,] in determining the amount of costs to award[,] chooses to consider the non-prevailing party's financial status, it should require substantial documentation of a true inability to pay. See McGill [ v. Faulkner], 18 F.3d [456,] 459 [(7th Cir.1994)] (non-prevailing party offered no documentary support, relying instead on "unsupported, self-serving statements"); Cherry, 186 F.3d at 447 (no reduction in cost award despite proof that plaintiff had "no independent income and owned no property in her own name" because she had "sufficient access to marital property" and a 401(k)plan).

Chapman, 229 F.3d at 1039; see also Corder v. Lucent Techs. Inc., 162 F.3d 924, 929 (7th Cir.1998) (stating that the burden is on the non-prevailing party to provide evidence of inability to pay sufficient to overcome the presumption that the prevailing party is entitled to recover costs); 10 Moore's Fed. Prac. § 54.101[1][b], at 54-154 to 54-155 (3d ed.2006) (stating that "[a] substantiated claim of the losing party's indigency may justify a reduction or denial of costs to the prevailing party, although such indigency is not an absolute shield to the imposition of costs") (footnotes omitted).

Moreover, the non-prevailing party must show more than a mere "drop in income" to substantiate his or her claim of indigency because such fact alone informs the court nothing of the non-prevailing party's "other financial resources." Carder, 162 F.3d at 929; see also 10 Moore's Fed. Prac. § 54.101[1][b], at 54-155. Cf. McGill, 18 F.3d at 459 (stating that incarceration alone is inadequate to show indigence). In A.D. v. Deere Co., 229 F.R.D. 189 (D.N.M.2004), the prevailing parties moved for costs against the non-prevailing parties pursuant to FRCP Rule 54(d). Id. at 192. The non-prevailing parties (A.D. and Sue Richins and Sue Richins as next friend of Arthur Dloyd Richins, Jr.) [hereinafter, collectively, the Richins] contended that costs should not be taxed against them inasmuch as "they currently have no earned income, and that they subsist on social security and worker's compensation." Id. In addition, the evidence in the case reflected that the Richins' future medical expenses, not all of which would be covered by worker's compensation, would exceed $2,000,000. Id. The Richins argued that they had "`practically' no ability to adequately care for A.D. Richards and thus cannot pay the [prevailing parties]' costs." Id. The United States District Court for the District of New Mexico (the court) held that, inasmuch as the Richins failed to overcome the presumption that the prevailing parties would recover costs, they did not demonstrate why the court should not award costs against the Richins. Id. at 193. Specifically, the court stated:

The Richins' claimed indigency is not an absolute shield to the award of costs. Moreover, the Richins have not shown that they are indigent such that the [c]ourt should not tax costs. It may well be that the Richins are unable to pay the costs. But given the record before the [c]ourt, the [c]ourt would be speculating to so find. While there certainly was evidence at trial that A.D. Richins' medical bills will be considerable, and that his earning capacity is limited, the [c]ourt does not recall evidence about the Richins['] assets. Normally, a balance sheet of the plaintiffs would not be relevant. At this stage, however, that information is needed. While the [c]ourt assumes that the Richins are of moderate means, they have not provided the detailed and specific information that the [c]ourt could use to determine whether they could pay an $8,000 cost bill.

Id. at 193-94 (citation omitted); see also Corder, 162 F.3d at 929 (holding that the trial court did not abuse its discretion when it refused to modify its costs order despite the losing party's allegation that her income had decreased).

Similarly, in the instant case, the evidence adduced at the circuit court level regarding the Pulawas' inability to pay costs taxed against them revealed that, as a result of Pulawa's severe head and brain injuries, he remains unemployable eight years after the accident. The Pulawas claim that they receive Social Security benefits, Operating Engineers Trust Funds benefits, and workers' compensation benefits. Finally, the Pulawas presented evidence that their taxable income in 2003 totaled $25,534. However, such evidence alone does not inform the court of the Pulawas' other financial resources. See Corder, 162 F.3d at 929; 10 Moore's Fed. Prac. § 54.101[1][b], at 54-155. Indeed, the Pulawas did not present any evidence about their assets. In other words, the circuit court was presented with evidence of the Pulawas' income stream after the accident, but not any evidence of the Pulawas' income stream prior to the accident and accumulation thereof. See, e.g., Broccoli v. Echostar Communications Corp., 229 F.R.D. 506, 517 (D.Md.2005) (district court concluding that losing party presented sufficient evidence of inability to pay costs due to low income and lack of any assets). In ruling on the plaintiffs motion, the circuit court stated that it had "reviewed the motion [to disallow costs] and heard the arguments" made by the parties, which focused on the plaintiffs' inability to pay. In taxing costs against the plaintiffs, the circuit court implicitly determined that the plaintiffs failed to rebut "[t]he presumption that the prevailing party is entitled to costs" "by some showing that an award would be inequitable under the circumstances." Wong, 88 Hawai'i at 52, 961 P.2d at 617. Therefore, inasmuch as the decision to award costs is discretionary and the circuit court "may," but need not, "consider the equities of the situation," HRS § 607-9, we cannot say that the circuit court's refusal to grant the plaintiffs' motion to disallow costs was an abuse of discretion in this case.

The concurring and dissenting opinion (the dissent), however, maintains that, because "HRCP Rule 54 is subject to HRS § 607-9," "[l]imitations on the trial court's consideration `of the equities of the situation' would violate the express language in HRS § 607-9." Dissent at 25, 143 P.3d at 1227. As such, the dissent proposes that trial courts may consider (1) "the chilling effect [that] a disproportionate award of costs may have on a person's right to bring suit," dissent at 26, 143 P.3d at 1228, and (2) "the relative disparity of wealth between parties," dissent at 25-26, 143 P.3d at 1227-28, in determining whether to assess costs pursuant to HRS § 607-9. Here, the plaintiffs on appeal never argued that: (1) imposing costs against them would result in a chilling effect on a person's right to bring suit; and (2) "relative disparity of wealth between parties" is a factor to be considered in determining whether to award costs. In fact, the entirety of the plaintiffs' argument pertaining to the circuit court's consideration of the equities in determining whether to assess costs against them states:

Evidence that an award is inequitable under the circumstances can provide a basis for denying costs. Wong v. Takeuchi, 88 Hawai'i 46, 52, 961 P.2d 611, 617 (1998) (citing 10 Moore's Fed[.] Prac[.] § 54.101(1)(a-b) (3d ed.1998)).

The most important equitable factor is indigency or inability to pay. In re Paoli Railroad Yard PCB Litigation, 221 F.3d 449, 463 (3rd Cir.2000). Such inability to pay permits a court to exempt the party from paying costs. Id. at 464.

The court awarded $35,463 in costs against [the plaintiffs]. This award was an abuse of discretion and both inequitable and erroneous.

Ben Pulawa sustained severe and permanent head and brain injuries and remains unemployable eight years later. His continued existence depends upon disability benefits from the Social Security Administration, Operating Engineers Trust Funds, and workers' compensation benefits. He has not been cleared for any form of employment over the past 8 years and has no prospect of becoming employable in the future.

(Citations to the record omitted.) Under the circumstances of this appeal, we, therefore, decline to consider any theories not advanced by the plaintiffs.

Finally, the dissent maintains that "remand is necessary in this case" because "fairness . . . dictates that [the p]laintiffs be given the opportunity . . . to show whether their assets are insufficient to satisfy [the] costs [taxed against them]." Dissent at 27-28, 143 P.3d at 1229-30. However, as the dissent points out, the plaintiffs already had the opportunity to support their position before the circuit court, namely, that "[c]ompelling equitable circumstances weigh heavily in favor of disallowing an award of costs[.]" Dissent at 27-28 n. 2, 143 P.3d at 1229-30 n. 2 (citation omitted). It was up to the plaintiffs to support their position in the first instance by adducing sufficient evidence to demonstrate a "true inability to pay." Chapman, 229 F.3d at 1039 (citations omitted). It may well be that the Pulawas are, in fact, unable to pay the assessed costs; nevertheless, given the state of the record, we defer, as we must, to the discretion of the circuit court in implicitly determining that the Pulawas failed to meet their burden of overcoming the strong presumption that E.E. Black and GTE, as the prevailing parties, recover costs pursuant to HRCP Rule 54(d). Indeed, as the Ninth Circuit has recognized:

Although a district court must "specify reasons" for its refusal to tax costs to the losing party, we have never held that a district court must specify reasons for its decision to abide the presumption and tax costs to the losing party. The distinction is critical. A district court deviates from normal practice when it refuses to tax costs to the losing party, and that deviation triggers the requirement to "specify reasons."

. . . .

The requirement that district courts give reasons for denying costs flows logically from the presumption in favor of costs that is embodied in the text of the rule[, i.e., FRCP Rule 54(d)]; if a district court wishes to depart from that presumption, it must explain why so that the appellate court will be able to determine whether or not the trial court abused its discretion. . . . Our requirement that a district court give reasons for denying costs is, in essence, a requirement that the court explain why a case is not ordinary.

This reasoning suggests, as we hold today, that a district court need not give affirmative reasons for awarding costs; instead, it need only find that the reasons for denying costs are not sufficiently persuasive to overcome the presumption in favor of an award. The presumption itself provides all the reason a court needs for awarding costs, and when a district court states no reason for awarding costs, we will assume it acted based on that presumption.

. . . .

[T]he district court needs no affirmatively expressed reason to tax costs. Rather, it need only conclude that the reasons advanced by the party bearing the burden — the losing party — are not sufficiently persuasive to overcome the presumption. In the circumstances of this case, the presumption itself provided an adequate reasons for the district court to award costs. We decline to adopt a rule that would place on district courts the burden of justifying routine awards of costs against losing parties[.]

Save Our Valley v. Sound Transit, 335 F.3d 932, 945-46 (9th Cir.2003) (citations and some emphasis omitted) (some ellipses and emphasis added). We likewise decline to adopt a rule that would place on circuit courts the burden of justifying a routine award of costs against losing parties. Such a burden may be incurred if we remand the instant case for a redetermination of the assessment of costs as the dissent would have it. Dissent at 27-28, 143 P.3d at 1229-30.

Accordingly, notwithstanding that the circuit court may, but need not automatically, exempt the plaintiffs from paying costs, we believe that the circuit court did not abuse its discretion in taxing costs against the plaintiffs. We, therefore, hold that the circuit court did not abuse its discretion in denying the plaintiffs' motion to disallow costs.

IV. CONCLUSION

Based on the foregoing, we affirm the circuit court's May 25, 2004 final judgment.
