Supreme Court won't hear appeal on state's campaign disclosure laws

The Supreme Court has rejected an appeal challenging campaign disclosure laws in Washington state.

The court on Tuesday let stand without comment a federal appeals court ruling that upheld the state's disclosure requirements. Human Life of Washington challenged the requirements as a violation of the First Amendment. The group didn't want to reveal its donors in a 2008 campaign opposing an assisted suicide ballot measure.

The San Francisco-based 9th U.S. Circuit Court of Appeals said the disclosure requirements "have become an important part of our First Amendment tradition."
