After five years of litigation, the state Supreme Court has ruled that the Philadelphia Parking Authority is not a unique state agency exempt from having to make regulations in accordance with the Commonwealth Documents Law.

The justices unanimously upheld Commonwealth Court rulings in three consolidated cases that invalidated the PPA’s regulatory scheme for taxicabs and limousines because the regulations were not filed with the Legislative Reference Bureau in accordance with the Documents Law, which requires that an agency invite and consider written comments from the public regarding proposed regulations.
