Anti-boycott laws have been challenged in federal court, including in Arkansas, Arizona, Georgia, Kansas, Maryland and Texas. Four federal district courts have ruled that these states’ laws, all of which require contractors with the state to sign pledges that they don’t boycott Israel, are likely unconstitutional and that boycotts for Palestinian rights are protected by the First Amendment. However, in each of these cases, the state legislatures changed the laws that were challenged so that they no longer applied to the plaintiffs in order to moot the lawsuits.
