The California State Court of Appeals today ruled unconstitutional a state law that makes it illegal to circulate a petition for a city initiative or referendum unless that circulator lives in that jurisdiction.

The decision says that a contrary decision from 1994 which upheld the law is no longer good law, given the 1999 U.S. Supreme Court decision—Buckley v American Constitutional Law Foundation—that struck down a Colorado law requiring circulators to be registered voters.

This is, indeed, good news, as the Buckley v American Constitutional Law Foundation decision should apply as well to Oklahoma’s residency requirement, currently being challenged by “Yes on Term Limits” in the 10th Circuit Court of Appeals in Denver.
