PORTLAND, Maine — The U.S. Supreme Court has declined to hear the first of two appeals brought by the National Organization for Marriage over campaign reporting requirements in Maine.

The Supreme Court issued its order on Monday, upholding Maine’s political action committee laws that the National Organization for Marriage said were vague and overly broad.

Still unsettled is a second appeal aimed at shielding the organization’s donor list.

NOM, which donated $1.9 million to help repeal Maine’s same-sex marriage law in 2009, said that releasing its donor list would stymie free speech and subject donors to harassment.

But the 1st Circuit Court of Appeals has upheld Maine laws that apply to political action committees, as well as the still-challenged ballot question committee requirements that would require the disclosure of NOM’s donor list.
