On July 18, the Michigan ACLU filed a federal lawsuit against officials of the Genesee County Parks Department, because the officials were attempting to outlaw petitioning within the Linden county park, except during daylight hours in a very small, isolated part of that park, and only for people who had first obtained a permit. On July 22 the officials conceded, and signed a consent decree that no one needs a permit to petition, and that most of the park is open to petitioning. See the complaint here. Thanks to Ballot Box News for this news. The plaintiffs are attempting to get signatures on a petition to recall the Governor.
Genesee County includes Flint. The case is Miller v McMillan, eastern district, 2:11-cv-13088.
