FITZGERALD, J.

This appeal arises from a wrongful death action brought by decedent's widow. Plaintiff contended at trial that her husband's death resulted from the negligence of defendant.

Defendant, an excavation contractor, was hired to excavate a trench on the premises of the Sunset Trailer Park in Sandusky, Michigan. The excavation was part of a planned expansion of the trailer park which required that a trench be dug from the existing septic system to the expansion sewer line.

The owner of the trailer park, Thomas Boyle, hired the prior owner, O.J. Campbell, to supervise the work involved in the expansion of the trailer park. Plaintiff's decedent, Milo Nichol, a retiree who resided in the trailer park, was also hired by Boyle to help with the expansion project.

On August 9, 1971, the excavation of the trench took place with defendant Billot, and Campbell and Nichol present. The trench was over 9 feet deep, 10 to 12 feet long, and 30 inches wide, and the walls were not sloped, braced or shored in any fashion.

After the excavation was completed, Nichol climbed into the trench for the purpose of making a hole in the septic tank. Shortly after he entered the trench the west wall collapsed and Nichol, who could not escape, was killed almost instantly.

Subsequently, plaintiff received workmen's compensation benefits from Boyle. Plaintiff then proceeded to bring suit against defendant as a third-party tortfeasor as allowed by MCL 418.827(1); MSA 17.237(827)(1).

At trial, plaintiff contended that defendant was an independent contractor and that he had negligently failed to slope the walls of the trench or to use bracing devices as required by accepted safety standards. Defendant relied upon two affirmative defenses. First, defendant claimed that he was not an independent contractor, but that he was a co-employee of decedent. Therefore he claimed that plaintiff's cause of action was barred by that provision of the Worker's Disability Compensation Act which bars all suits against co-employees for injuries sustained in circumstances otherwise compensable under the act. MCL 418.827(1); MSA 17.237(827)(1). Second, defendant claimed that plaintiff's decedent was contributorily negligent.

After a three-day trial in March 1976, the jury returned a verdict of no cause of action.

The Court of Appeals affirmed the jury's verdict, with Judge BRENNAN dissenting. 80 Mich. App. 263; 263 N.W.2d 345 (1977).

We granted leave to consider the following two issues:

(1) In a tort action where the defendant relies on the affirmative defense that the plaintiff's exclusive remedy is under the Worker's Disability Compensation Act and the basis of such affirmative defense is the co-employee status of the plaintiff and defendant, what is the proper test by which to determine whether the plaintiff and the defendant are co-employees; and

(2) Whether the question of defendant's status is an issue of law for the court or an issue of fact for the jury. 402 Mich. 922 (1978).

I

At trial, plaintiff contended that because defendant asserted an affirmative defense based on a provision of the workmen's compensation statute, the proper test to determine the employment status of defendant was the economic reality test. However, the trial court agreed with defendant that the economic reality test was limited to workmen's compensation cases and instructed the jury to apply the control test.

The Court of Appeals majority agreed with the trial court, stating that the mere fact that a defendant asserts the co-employee immunity from suit provision of the workmen's compensation statute does not mean that the economic reality test must be applied in a tort action. Judge BRENNAN favored the economic reality test as the logical test to use in deciding whether a defendant can use the Worker's Disability Compensation Act as a shield against a plaintiff.

Prior to Tata v Muskovitz, 354 Mich. 695; 94 N.W.2d 71 (1959), the only test for determining whether a person was an employee or an independent contractor centered on the question of control. The control theory is the traditional common-law test used to delineate the master-servant relationship. The theory, in its delineation of the servant concept, has for its purpose the definition and delimitation of the scope of the master's liability under the doctrine of respondeat superior. Because most compensation acts contain no specific definition of the term "employee", it was generally taken for granted that the common-law definition of employee, or servant, used for purposes of vicarious tort liability was to be used for purposes of workmen's compensation laws.

In Tata v Muskovitz, supra, this Court adopted the dissenting opinion of Mr. Justice TALBOT SMITH in Powell v Employment Security Comm, 345 Mich. 455; 75 N.W.2d 874 (1956), in which he set forth the economic reality test as the proper guide to relevant interpretation of the workmen's compensation statute. See, also, Schulte v American Box Board Co, 358 Mich. 21; 99 N.W.2d 367 (1959); Goodchild v Erickson, 375 Mich. 289; 134 N.W.2d 191 (1965); Solakis v Roberts, 395 Mich. 13; 233 N.W.2d 1 (1975); Askew v Macomber, 398 Mich. 212; 247 N.W.2d 288 (1976).

Justice SMITH expanded on the relevant factors to be considered under the economic reality test in Schulte v American Box Board Co, supra, p 33:

"This is not a matter of terminology, oral or written, but of the realities of the work performed. Control is a factor, as is payment of wages, hiring and firing, and the responsibility for the maintenance of discipline, but the test of economic reality views these elements as a whole, assigning primacy to no single one."

Also, in determining the economic realities a court is to determine whether the work being performed is an integral part of the regular business of the employer, "a contribution to the accomplishment of a common objective". Powell v Employment Security Comm, supra, 478. See, also, McKissic v Bodine, 42 Mich. App. 203; 201 N.W.2d 333 (1972).

The ultimate purpose of the economic reality test is to effectuate the goals of the social legislation by determining whether or not the relationship is of the type intended to be protected by the act. National Labor Relations Board v Hearst Publications, Inc, 322 U.S. 111; 64 S Ct 851; 88 L Ed 1170 (1944); United States v Silk, 331 U.S. 704; 67 S Ct 1463; 91 L Ed 1757 (1947); Powell v Employment Security Comm, supra, 478.

The circumstances presented in the instant case do not fit neatly into the purposes sought to be effectuated in either the control test or the economic reality test. In the present case, there is no respondeat superior liability involved, nor is there any application for workmen's compensation benefits involved. Thus, we must determine which test, if either, should be applied in this particular situation. We will consider the application of each test seriatim.

Defendant argues that because this is a tort suit the control test is applicable and that the economic reality test is inapplicable because that principle has been confined to workmen's compensation cases.

We think that it is necessary to distinguish the present case from those tort actions which involve the vicarious liability of a master for the acts of his servant vis-a-vis a third party. The instant case is atypical of those cases to which the control test has been traditionally applied in that there is no vicarious liability involved here. Rather, the liability of defendant for his own acts is the only liability at issue.

As stated above, the purpose of the control test is to define and delimit the circumstances under which a master should be held liable for the acts committed by a servant which injure a third party. As described by Larson in his treatise on Workmen's Compensation Law:

"The `servant' concept at common law performed one main function: to delimit the scope of a master's vicarious tort liability. This tort liability arose out of detailed activities carried on by the servant, resulting in some kind of harm to a third person. The extent to which the employer had a right to control these detailed activities was thus highly relevant to the question whether the employer ought to be legally liable for them."

The control test is also used to determine when an independent contractor has become an employee for purposes of respondeat superior liability on the part of his employer who has exercised a degree of control inconsistent with independent contractor status. Powell v Employment Security Comm, supra, 471.

In his closing argument, defense counsel admitted that his client was for general purposes an independent contractor, but contended that in this instance, because Campbell exercised control over him, defendant became an employee.

In Powell, supra, 471, Justice SMITH stated the following:

"It is a complete perversion of this principle [i.e., that an independent contractor is liable for his own torts unless his employer assumes control] to employ the control exception (an independent contractor does not remain such if made subject to control) as a test for his status as an independent contractor in the first place. It is much as though we employed the well-known exceptions to the corporate entity doctrine as tests for the existence of the corporation itself. Confusion is inevitable."

As indicated by Justice SMITH, the control test is not intended to be a definition of independent contractor status in the first place. It is also a misuse of the control test to use it as a definition of employee status for purposes other than for which it was originally intended. The adoption of the control test at common law in order to determine the applicability of the servant concept was limited to those situations where the question was whether it was appropriate to apply the theory of respondeat superior. Therefore, because there is no question of the vicarious liability of a master involved here, we find the control test to be inappropriate.

Turning to the economic reality test, we find that although actual payment of workmen's compensation benefits is not at issue here, significant objectives of the workmen's compensation statute are involved.

A recipient of workmen's compensation benefits is limited in his right to sue those persons responsible for his injuries. A recipient of benefits may not sue his employer or a fellow employee. MCL 418.131; MSA 17.237(131); MCL 418.827(1); MSA 17.237(827)(1). With permission of § 827(1), a recipient may bring an action for wrongful death against third parties other than employers or fellow employees. Hix v Besser Co, 386 Mich. 499; 194 N.W.2d 333 (1972).

Thus, while one of the purposes of § 827(1) is to prohibit suits by compensation recipients against co-employees, another purpose of that same section is to permit the recipient recovery for his injuries beyond the statutory benefits through the provision allowing suit against certain negligent third parties.

An independent contractor is a third party subject to suit under § 827(1). This is appropriate because an independent contractor is often in as good a position as, if not better than, his employer to know the hazards of his trade and the concomitant safety precautions. To allow the independent contractor to abandon accepted safety measures and then disclaim responsibility for his omission because his employer exercised some degree of control would not only deprive a compensation recipient of his opportunity to sue under § 827(1), it would also seriously endanger the safety of workers such as the deceased.

Thus, we conclude that other factors beyond the control element should be considered before we extend the bar to plaintiff's common-law right to sue in this situation. We find that the economic reality test provides those other factors. In emphasizing a "freer and more realistic balancing of all the relevant factors in each case" to determine which persons are properly denominated employees, the test also necessarily achieves a freer and more realistic determination of which persons should be properly denominated independent contractors.

Although workmen's compensation benefits are not at issue here, the policies behind the act are involved through the invocation of § 827(1). We think that as the economic reality test is the appropriate test to determine which persons are intended to be included within the act, it is also the appropriate test to determine which persons should not be subject to the act's bar against common-law remedies. Because the act is concerned with the correction of economic evils through remedies unknown to the common law, the control test, a creature of common law, is not responsive to the provisions of the statute. We deem it appropriate to apply the principle which accomplishes the purpose of the social legislation involved here, which is to afford maximum benefit to injured parties. As it is defendant who relies on the worker's compensation act to support his defense, he should not be heard to complain that a rule utilized to construe the act's provisions is to be employed.

In conclusion, we find that the application of the control test in a tort action where respondeat superior liability is not involved is inappropriate. We hold that the economic reality test, in its consideration of factors beyond the control element, achieves a more realistic determination of the independent contractor/employee question in cases where the affirmative defense of co-employee immunity under § 827(1) is utilized.

II

We must next determine whether the question of defendant's status is an issue of law for the court or an issue of fact for the jury.

Both parties take positions on this issue which are inconsistent with the ones they asserted prior to trial. Shortly after suit was commenced, defendant moved for summary judgment claiming that he was a co-employee of plaintiff's decedent and that plaintiff's suit was barred by the operation of § 827(1). At that juncture, plaintiff opposed the motion, arguing that there were disputed facts concerning the issue of defendant's status and that the issue should be submitted to the jury. The trial judge denied defendant's motion, holding that the issue presented was a question of fact.

Subsequently, at the close of the proofs, plaintiff's attorney moved to strike defendant's affirmative defense based on § 827(1). He contended that there were no disputed questions of fact regarding the relationship and thus it was a question of law for the judge to decide. Defense counsel opposed the motion, arguing that it was a question of fact for the jury to resolve. The trial court denied plaintiff's motion, ruling that there were facts upon which reasonable minds could differ.

On appeal, the parties retain their latter positions, with plaintiff contending there existed no factual dispute regarding defendant's status, and with defendant contending there existed questions of fact on this issue.

The Court of Appeals majority held that there were issues of fact to be determined preliminary to the disposition of the independent contractor/employee question. As one example of such factual issues, the court stated that plaintiff claimed defendant was an independent contractor while defendant claimed that Campbell exercised complete control over him. The Court of Appeals majority obviously was influenced in their decision on this issue by their previous determination that the control test was the proper theory to be applied.

The dissent concluded that the question of defendant's employment status was one of law, citing this Court's decision in Askew v Macomber, supra. Askew involved an appeal from a Workmen's Compensation. Appeal Board decision. We noted there that the appellate courts of this state are bound by the appeal board's findings of fact. In Askew, we said that the question of whether the defendant therein was the plaintiff's employer for purposes of workmen's compensation was an issue of law properly left to our determination.

In Askew, we cited Renfroe v Higgins Rack Coating Manufacturing Co, Inc, 17 Mich. App. 259, 262; 169 N.W.2d 326 (1969). The Renfroe Court's analysis of the issue presented herein is instructive:

"In the case at bar, the record contains numerous interrogatories, depositions, and affidavits, which set out the underlying events and circumstances in great detail. These, as well as the agreed statement of facts submitted for purposes of this appeal, reveal that there is no dispute as to any of the underlying facts. Plaintiff's only contention is that on the basis of the agreed facts, defendant should not be labeled an `employer' within the meaning of the workmen's compensation law. This is not a question of fact for a jury to decide; it is a question of law which must ultimately be decided by the courts."

However, in both Askew and Renfroe the reviewing Court was bound by the facts below, the former case involving findings of fact by the WCAB and the latter involving facts stipulated by the parties. Thus, all issues of fact as well as the usual process of drawing permissible inferences from testified facts were thereby eliminated, and all that was necessary was that the court apply the relevant legal principles.

It is a basic proposition of law that determination of disputed issues of fact is peculiarly the jury's province. Wight v H G Christman Co, 244 Mich. 208, 211; 221 N.W. 314 (1928). Even where the evidentiary facts are undisputed, it is improper to decide the matter as one of law if a jury could draw conflicting inferences from the evidentiary facts and thereby reach differing conclusions as to ultimate facts. See Simerka v Pridemore, 380 Mich. 250; 156 N.W.2d 509 (1968) (SOURIS, J.).

In Flick v Crouch, 434 P.2d 256 (Okla, 1967), the Oklahoma Supreme Court expressed a rule which incorporates the principles we have expressed above and applied it to a case which contains a question similar to that which confronts us herein. Flick involved a wrongful death action brought by a widow of a deceased workman against a third party. Oklahoma also has a provision in its workmen's compensation statute which accords immunity to the employer and his employees from common-law liability for negligence. Okla Stat 1961, tit 85, § 44(b). The question involved in Flick was whether the defendants were independent contractors or employees as determined by the various factors applied by Oklahoma courts which are virtually identical to the factors considered in this state under the economic reality test. The Flick Court set forth the following rule:

"When a defendant's status forms a material issue in an evidentiary proceeding, * * * which has for its object to determine whether the action sought to be prosecuted is one abrogated or taken away by the Workmen's Compensation Law, * * * or `reserved' to the workman (or his widow) * * * the rule to be applied by the trial court should be the same as that which governs at the trial: if the evidence concerning the status of a party defendant is reasonably susceptible of but a single inference, the question is one purely of law to be decided by the court * * * but where the facts bearing on such issue are either disputed, or conflicting inferences may be reasonably drawn from the known facts, it is error to withhold the issue from the determination of the jury."

In applying the Flick rule to the instant case, we find that the evidentiary facts were undisputed and that they were susceptible of only one inference, that is that defendant was an independent contractor.

After reviewing the trial transcript and the briefs we find that the only element of the economic reality test in question was whether the interpretation of evidence bearing on the issue of control was such as to establish an employee relationship. In addition, in his brief defendant accepts plaintiff's statement of facts with the exception of any conflict with three paragraphs which defendant sets forth in his own statement of facts. In those three paragraphs defendant presents his theory of the case and additional evidence to support his theory of control.

However, assuming arguendo that the control element has been established, it would not be sufficient to satisfy defendant's burden of proof on the affirmative defense. Under the economic reality test control is only one of several factors to be considered. Powell v Employment Security Comm, supra, 479 (SMITH, J., dissenting). The economic reality test "views these elements as a whole, assigning primacy to no single one". Schulte v American Box Board, supra, 33 (SMITH, J., concurring). (Emphasis added.)

Although we realize that defendant was laboring under the impression at trial, as affirmed by the trial court, that the control test applied and therefore may have felt that it was unnecessary to introduce evidence pertinent to the other factors of the economic reality test, we do not believe that it is necessary to remand for a new trial on this basis for several reasons.

First, the trial court did not rule until the close of the proofs that the control test, and not the economic reality test, was the applicable rule.

Second, plaintiff elicited abundant evidence from the witnesses regarding the other elements of the economic reality test and defendant did not rebut this evidence.

Third, defendant accepts (with the exception noted above) plaintiff's statement of facts. Those facts include the following:

"Mr. Billot testified that, in 1971, he and his father owned a small business known as Billot Excavating Company. They owned a backhoe, a bulldozer, a front-end loader and three trucks. This company did excavating, roadbuilding, leveling, grading and hauled sand and gravel.

"In 1971 Mr. Billot considered himself as being self-employed. He handled his own social security and income tax deductions. When hired to do excavating work he was not carried on the employment rolls of the person who hired him. He was paid $12 per hour for the use of the backhoe. He supplied all of his own equipment and materials and did all of his own maintenance to such equipment.

"When Mr. Billot did work for Mr. Boyle on the trailer park he received a flat rate for the time that he spent. Mr. Boyle did not deduct social security or income taxes from Mr. Billot's bills. Mr. Boyle never sent Mr. Billot a W-2 statement, or even took his social security number.

"During the summer of 1971, Mr. Billot worked for a number of different people or companies, sometimes working for as many as three people in a single day. Mr. Billot arranged his own schedule.

"Mr. Billot testified that if Mr. Boyle had told him not to work or fired him, he would have no right to draw unemployment compensation and would have no seniority or other employment rights. He further testified that he was not hired to do anything having to do with the operation of the trailer park, but only to perform the special project of digging the trench.

"Mr. Billot testified further that he did not depend on his income from Mr. Boyle to support himself, but that he had many customers. He held himself out to the public, through the Yellow Pages of the phone book, as a contractor skilled in the doing of excavating work. Furthermore, it was the custom of the community that such work was ordinarily done by independent contractors. In fact, when Mr. Billot was hired by Mr. Boyle, he did not think of himself as an employee of Mr. Boyle. He felt that he had the right to hire a helper or substitute."

The above excerpt, as verified by the trial transcript, leads us to one conclusion. Applying the economic reality test to the instant case, we find that all of the elements, with the possible exception of control, clearly point to defendant's independent contractor status. Thus, we conclude as a matter of law that defendant was an independent contractor.

CONCLUSION

The economic reality test is the proper test to determine co-employee status in a tort suit where respondeat superior liability is not at issue and where the affirmative defense of co-employee immunity under the workmen's compensation statute is asserted.

In order to determine whether the question of defendant's status is an issue of law for the court or an issue of fact for the jury the following rule is applicable:

"[I]f the evidence concerning the status of a party defendant is reasonably susceptible of but a single inference, the question is one purely of law to be decided by the court * * * but where the facts bearing on such issue are either disputed, or conflicting inferences may be reasonably drawn from the known facts, it is error to withhold the issue from the determination of the jury." Flick v Crouch, supra.

In the instant case, we conclude, as a matter of law, that defendant was an independent contractor. Because it is unclear whether the jury's verdict was based on § 827(1) or contributory negligence, we remand to the trial court for a new trial on the issue of negligence.

Reversed, with costs to plaintiff.
