A Manhattan judge sided with New York Attorney General Eric Schneiderman Monday in shooting down a lawsuit filed by Citizens United over the disclosure of key information about the group’s donors.

The conservative not-for-profit sued Schneiderman in 2014 in order to block him from making it reveal the names, addresses and contribution amount from donors before soliciting state funds — as charitable organizations are required to disclose.

Citizens United argued it was in violation of its First Amendment rights and invaded the privacy of its donors.

“The complaint states not a single plausible claim upon which relief can be granted,” federal judge Sidney Stein wrote in an 18-page opinion that granted Schneiderman’s motion to dismiss.

Last year, then judge also dismissed Citizens United’s motion for a preliminary injunction against the enforcement of the state policy.

“Today’s decision is a victory for common sense oversight of New York’s vast nonprofit sector. New Yorkers deserve to know their donations are protected against fraud and abuse, and today the court protected that right by dismissing each and every one of Citizen United’s claims,” Schneiderman said in a statement.

Michael Boos, a lawyer for Citizens United, said it’s considering appealing.

“We are quite disappointed by today’s ruling dismissing Citizens United’s federal civil rights lawsuit against New York Attorney General Eric Schneiderman, which challenges his unconstitutional policy requiring non-profit organizations to disclose their most valuable donors to his Charities Bureau in order to lawfully solicit contributions in New York State,” Boos said.

In 2010, the watchdog group won a US Supreme Court case allowing unions and corporations to spend an unlimited amount in campaign donations.
