The U.S. Supreme Court on Monday declined to take up a case challenging a Montana disclosure law.

Specifically, the law requires disclosure of spending for political ads within 60 days of an election.

In August 2019, the 9th U.S Circuit Court of Appeals upheld Montana’s law requiring nonprofit groups running ads mentioning candidates, political parties or ballot issues in the 60 day window before an election to report any spending of $250 or more and disclose who funded their efforts.

This law is part of the state’s Disclosure Act, while the case was filed by the National Association of Gun Rights in 2016.

In their lawsuit, the group stated they were planning on sending mailers in Montana.

However, they would not report their donors or spending because it violated their constitutional rights of free speech.
