The Iran Nuclear Agreement Review Act of 2015 (INARA) (H.R.
1191, 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.
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.
[2] 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.
