A lawsuit filed by the Illinois Opportunity Project over Montana Gov. Steve Bullock’s executive order on dark money in elections has been dismissed.

The Illinois-based conservative advocacy group filed the lawsuit in U.S. federal court in Helena objecting to Executive Order 15-2018.

The Executive order requires organizations receiving large state contracts to report political contributions that exceed $2,500, even if the disclosures are not required under federal election laws.

Judge Charles C. Lovell ruled the Illinois Opportunity Project could not prove it had been harmed by the executive order because current or potential donors refused to contribute money because they would be named.

The advocacy group has until January 21 to file an amended complaint.
