Iran Nuclear Agreement Review Act of 2015

The Iran Nuclear Agreement Review Act of 2015 (INARA) (, Pub.L 114–17) is a bill that was passed by the US Congress in May 2015, giving Congress the right to review any agreement reached in the P5+1 talks with Iran aiming to prevent Iran from obtaining nuclear weapons.

The bill passed in the Senate by a 98–1 vote (only Tom Cotton voted against), and then passed in the House by a vote of 400–25 on May 14. President Barack Obama threatened to veto the bill, but eventually a version arrived that had enough support to override any veto and Obama did not try vetoing it.

Larry Klayman filed a lawsuit, alleging that the law was an unconstitutional abrogation of the Senate's Treaty Power. The lawsuit was dismissed for lack of standing.

A group of Republican Senators said an agreement to return to the [Joint Comprehensive Plan of Action] (JCPOA) required congressional review under INARA, while others said the JCPOA has already been through such a review.
