California Union Insurance Co. v. Trinity River Land Co‪.‬

May a municipality constitutionally place a limit on the size of contributions to committees formed to support or oppose ballot measures? We conclude that while the challenged legislation must be examined with great care, such a limit is constitutional because it serves compelling governmental interests without unduly infringing upon First Amendment rights. Although resolution of a conflict between fundamental interests such as these is never easy, in this instance the balance favors allowing government regulation.
