The contribution limit on independent expenditure groups in New York was struck down by a federal judge in Manhattan on Thursday.

The ruling — which U.S. District Court Judge Paul Crotty said was based in part on a U.S. Supreme Court decision that rejected aggregate limits on political contributions in an election cycle — is seen as having the potential to bring in a new era of super PACs and their unlimited spending in state political campaigns.

“I think there is a risk of quid pro quo corruption, but the Supreme Court has not recognized it,” he said during a hearing in Manhattan federal court, according to Reuters. “We know what the Supreme Court has held, whether we like it or not, and I’m bound to follow it.”

The challenge to New York’s independent expenditure limits and the aggregate caps at the federal level was brought by the same donor: Shaun McCutcheon, an Alabama resident who contributed $60,000 to a super PAC supporting Republican mayoral candidate Joe Lhota.

The group, New York Prosperity and Protection PAC, had also received a $200,000 from industrialist David Koch, the co-founder of the prominent super PAC Americans for Prosperity.
