The Maine Supreme Judicial Court on Tuesday refused to block a ruling ordering the National Organization for Marriage (NOM) to file a public report identifying the sources of the $2 million it gave to the 2009 people's veto campaign that repealed a gay marriage law approved by lawmakers.

Three years after NOM and its supporters repealed the law, voters reversed course, making Maine the first state in the nation to legalize such unions at the ballot box.

Last year, the Maine Commission on Governmental Ethics and Election Practices unanimously imposed a record $50,250 fine against NOM for violating Maine's donor disclosure laws.

“The time has come for them to finally comply with state law like everyone else,” Attorney General Janet Mills told the Portland Press Herald. “The people of Maine have a right to know who is paying to influence our elections.”

NOM contributed more than $2 million to the $3 million campaign to uproot the marriage law. The referendum campaign was led by Stand for Marriage Maine, a Maine-based ballot question committee. NOM has argued that it donated money to the committee from a general fund.

However, NOM President Brian Brown was an operating officer at Stand for Marriage Maine, which critics argue allowed NOM to skirt Maine's laws.
