State v. LeMaster
In State v. LeMaster, 669 P.2d 592 (Ariz. App. 1983), the Arizona court recognized that it "has indicated that prospective application of a decision means that a decision applies to cases tried after the date of filing as well as to cases pending on appeal as of that date." 669 P.2d at 601.
The court noted that such "interpretation is consistent with the general rule that when there is a change of law by judicial decision between the time of trial and the time of appeal the appellate court will apply the law prevailing at the time of the appellate disposition." Id.
