An Allegheny County judge on Friday dismissed a petition that sought to initiate annexation proceedings for Wilkinsburg to be incorporated into the City of Pittsburgh. The petition, filed on Sept. 29, was dismissed in a two-page order by Senior Common Pleas Judge Joe James. In the order, James wrote that the only acceptable procedure for annexation comes from Pennsylvania’s constitution, which requires a referendum in which a majority of voters from each municipality approve the merger.
