Following the passage of the Property Protection Act in North Carolina during 2015, litigation resulted in a 2017 decision that the law violated constitutional provisions relating to First Amendment rights. Accordingly, The Attorney General of North Carolina has filed an appeal to  SCOTUS with the North Carolina Farm Bureau joining the petition. Opponents include the People for the Ethical Treatment of Animals and the Animal Defense Fund as respondents

The law passed in 2015 was intended to restrict release of confidential information relating to farms and processing plants and included a ban on  alternatives including audiovisual recordings.

Ag-gag laws have had little success in restraining activist organizations from either intruding on to farms or placing agents in animal production and processing facilities.  Ag-gag laws enacted in Iowa and Kansas have been struck down and SCOTUS declined to hear a petition submitted by Kansas.
