In Skyvue Terrace, Inc. v. Department of Public Welfare, 85 Pa. Commw. 123, 482 A.2d 58 (Pa. Cmwlth. 1982), the Court declined to apply 1 Pa. Code 31.2 so as to excuse a party's failure to comply with a regulation relating to the timeliness of filings. Determining the language of the regulation at issue was clear with regard to the method for filing certain documents, we rejected a party's argument that the clear regulatory language should be disregarded by applying a liberal construction to a clear regulatory requirement.
