California foie gras ban (2012)
California banned the sale of foie gras produced by force-feeding. Producers sued, arguing the law violated interstate commerce. The case went to the Supreme Court.
The ban took effect, was briefly blocked, then enforced.
In 2023 the Supreme Court declined to hear the producers' challenge, leaving the ban in place.
Shows that foie gras bans can survive legal challenges, but only after years of litigation.
