Rule 40 - Assignment of Cases for Trial: Continuances(a) Assignment of Cases for Trial. Cases may be assigned to the appropriate calendar or list for trial or other disposition by order of the court including general rules and orders adopted for the purpose of assignment. Precedence shall be given to actions entitled thereto by statute. (b)Continuances. Continuances shall be granted only for good cause, in accordance with general rules and orders which the court may from time to time adopt. (c)Affidavit or Certificate in Support of Motion. The court need not entertain any motion for a continuance based on the absence of a material witness unless such motion be supported by an affidavit which shall state the name of the witness and, if known, his address, the facts to which he is expected to testify and the basis for such expectation, the efforts which have been made to procure his attendance or deposition, and the expectation which the party has of procuring his testimony or deposition at a future time. Such motion may, in the discretion of the court, be denied if the adverse party will admit that the absent witness would, if present, testify as stated in the affidavit. The same rule shall apply, with the necessary changes in points of detail, when the motion is grounded on the want of any material document, thing, or other evidence.
