I'm not aware of any laws allowing "reserved" hadicap parking .. if you have the placard, you can park in a handicap spot .. it's the law ( https://www.state.nj.us/humanservices/dds/home/Guide to Accessible Parking-Web.pdf )
This is getting weirder ...
so it was a reserved private parking lot with permit only parking.......*someone* thought they could park in a poorly labeled spot in the *private.permit.only.lot* and just get away with it because it was a handicap spot.
