The act (1 Pa.C.S. § 1938) provides that a reference in a statute to a governmental agency, department, board, commission or other public body or to a public officer includes an entity or officer which or who succeeds to substantially the same functions as those performed by such public body or officer on the effective date of the statute, unless the specific language or the context of the reference in the statute clearly includes only the public body or officer on the effective date of the statute.
