That's the ticket. Also, in addition to suing the city, sue all "individuals" responsible for violating this farmer's 1st amendment rights.
Beyond suing in civil court there may be the possibility of criminal prosecution. If criminal laws were broken in denying the farmer his rights - insist that the DA prosecute the criminals.
This could be a win-win for our state’s attorney general, Bill Schuette, to get involved with. Lansing or Kent county’s lawyers aren’t going to touch this.
