On March 8, U.S. District Court Judge Mark R. Hornak, an Obama appointee, permanently enjoined Allegheny County from invalidating local initiatives on the basis that the petitions were gathered by someone from outside Pennsylvania. OpenPittsburgh.org v Voye, w.d., 2:16cv-01075. This case is very old and had been filed in 2016.
Here is the 13-page order, which lists other lawsuit decisions recently that struck down bans on out-of-state circulators, including two in 2022, from Maine and Montana. The order does not declare the Pennsylvania ban on out-of-state circulators to be unconstitutional, only because of procedural reasons, but it makes it clear that if the court had been asked to declare it unconstitutional, it would have been declared unconstitutional.
