A federal lawsuit aimed at overturning a voter-approved 2018 Florida constitutional amendment that restricts lobbying activities by former and current elected officials is gaining plaintiffs, with Leon County Commissioner Bill Proctor recently joining the legal fight.

The civil lawsuit seeking a preliminary injunction against Florida Amendment 12 was filed last month in the Southern District of Florida. That amendment, which was approved with nearly 79% of the statewide vote, would prohibit public officials from being paid lobbyists during their terms of office and for a period of six years after leaving elective office.

The measure was placed on the ballot on a 30-4 vote by the state Constitution Revision Commission, which meets every two decades to propose changes to the Florida Constitution.
