The United States Supreme Court has decided not to hear a case involving Maine’s political contribution disclosure, upholding the law. The National Organization for Marriage (NOM) had appealed to the country’s highest court after an appeals court ruled that Maine’s law regarding ballot issue committees is constitutional.

The law states that groups who spend more than $5,000 to influence ballot questions must register with the state ethics commission. Once registered, organizations must identify, in filed campaign finance reports, any donors who contributed more than $100.

The ethics commission, due to the ongoing legal battle, has not made a final determination on whether NOM is actually a ballot issue committee. The commission hopes to have a final answer on that issue in the coming months.
