Last week, a federal judge upheld Alaska’s strict limits on several types of state-level campaign contributions, ruling that they don’t violate the free speech or equal protection clauses of the U.S. Constitution.

The suit was brought by three individuals and District 18 of the Alaska Republican Party against the Alaska Public Offices Commission. The lawsuit challenged state law that prohibits an individual from donating more than $500 annually to a candidate. The lawsuit also sought to overturn state law that sets limits on the amount a candidate can accept from nonresidents and the amount a political party may contribute to a candidate.

All of the challenged provisions of Alaska’s campaign finance laws were upheld as constitutional.
