The ninth circuit in 2022 upheld a lower court’s 2020 ruling, which allowed residents to purchase foie gras for their individual use from out-of-state retailers.

[9] The certiorari petition was filed on March 9, 2018, and denied on January 7, 2019, leaving the lower court ruling in effect.

[12] The law included a provision that it would take effect almost eight years after enactment in order to allow time for techniques to be developed by which foie gras could be produced without force-feeding birds.

[16] A lawsuit was filed in U.S. District Court in Los Angeles on July 2, 2012,[17] seeking to overturn the California foie gras law on the ground that it is unconstitutionally vague.

[20] On July 18, 2012, U.S. District Court Judge Stephen V. Wilson denied the plaintiffs' request for a temporary injunction that would have immediately suspended the foie gras ban.

[21] On September 19, 2012, Judge Wilson denied the plaintiffs' request for a preliminary injunction against enforcement of the law.

[25][26] In January 2014, the Ninth Circuit Court of Appeals denied a request by foie gras proponents to reconsider their challenge to the law.

[31] On September 15, 2017, the three-judge panel unanimously [8] reversed U.S. District Judge Stephen V. Wilson's January 7, 2015 decision, finding that the California foie gras law is not preempted by the federal Poultry Products Inspections Act.
