In Larocca v. Workmen's Comp. Appeal Bd. (The Pittsburgh Press), 140 Pa. Commw. 192, 592 A.2d 757 (Pa. Cmwlth. 1991), the Court relied upon Appellate Rule 1503 in determining that IOP 211 was not an impermissible enlargement of the time to file a petition for review in contravention of Appellate Rule 105(b). Appellate Rule 1503 provides: If an appeal is taken from an order of a government unit, or if a complaint in the nature of equity, replevin, mandamus, or quo warranto, or a petition for a declaratory judgment or for a writ in the nature of certiorari or prohibition is filed against a government unit or one or more of the persons for the time being conducting its affairs objecting to a determination by any one or more of them, this alone shall not be a ground for dismissal. The papers whereon the improvident matter was commenced shall be regarded and acted upon as a petition for review of such governmental determination and as if filed at the time the improvident matter was commenced. The court may require that the papers be clarified by amendment. Pa. R.A.P. 1503.
