The U.S. Postal Service promulgated a new regulation on December 1, 2005, allowing petitioning on sidewalks that are parallel to streets. Petitioning on sidewalks that go from a parking lot to the door of the post office is still illegal, but the constitutionality of that ban is now back in U.S. District Court. The new regulation says that people can stand on any sidewalks and ask people to sign, but the person holding the clipboard must be on a sidewalk that is parallel to the street, not on an interior sidewalk.
