In Dioguardi v. Superior Court, 184 Ariz. 414, 417, 909 P.2d 481, 484 (App. 1995) the Court found invalid a rule promulgated by the Arizona Board of Medical Examiners that set a time limit for filing motions for rehearing, thereby reducing by one-third the period within which a physician must act to seek review of a decision by the board. 184 Ariz. at 417-18, 909 P.2d at 484-85. The court rejected the board's argument that the regulation differed only slightly from the requirements of Rule 59, Ariz. R. Civ. P., which A.R.S. 41-1062 directs that any regulations must follow "as closely as practicable." Dioguardi, 184 Ariz. at 418, 909 P.2d at 485.
