NPT withdrawal bill

Iranian bill to exit the NPT, awaiting Speaker approval for floor debate, 20 Sep 2026

Iran's parliament has produced two separate bills to leave the Nuclear Non-Proliferation Treaty. A March 2026 bill cleared committee but never reached a floor vote; a second, triple-urgency bill filed on 20 September 2026 now awaits scheduling by Speaker Qalibaf.

Background

MP Malek Shariati uploaded the first NPT withdrawal bill to Iran's parliamentary portal on 28 March 2026, tagged as priority legislation, alongside a separate bill to write Iran's Hormuz transit toll into permanent law. A parliamentary committee approved the measure, but the Majlis did not reconvene to hold a full floor vote and the bill stalled there. In practice the suspension of IAEA cooperation, which the Majlis passed 221-0 days later, achieved much of what formal withdrawal would have without the bill ever coming to a vote.

A separate, later bill has since taken its place as the live legislative vehicle. MP Hossein-Ali Haji Deligani filed a triple-urgency bill on 20 September 2026, five days after 130 deputies petitioned for withdrawal; triple urgency compresses debate, vote and clerical vetting into a single sitting day. As of that date Speaker Mohammad Baqer Qalibaf had not scheduled it, and filing alone does not start the treaty's 90-day exit notice clock.

Either bill, if passed, would make Iran only the second state to leave the NPT after North Korea in 2003, formally ending the IAEA safeguards obligations that already have no practical access to Iran's programme. Iran held roughly 440 kg of 60%-enriched uranium beyond inspector reach as of the treaty debate's most recent phase, material that would be freed from any treaty-based oversight regime if a withdrawal bill eventually passes.

Common Questions
Is Iran leaving the NPT?
A triple-urgency bill sits with Parliament's Presiding Board, filed 20 September 2026 by MP Hossein-Ali Haji-Deligani. It has not reached a floor vote and Speaker Qalibaf has not scheduled it. Senior officials say Iran is not leaving the NPT for now.Source:
What is the NPT withdrawal bill?
Iranian legislation to formally exit the Non-Proliferation Treaty, repeal Iran's domestic nuclear-commitment law, and endorse a new nuclear-cooperation framework with Russia, China and other non-Western states.
Has any country left the NPT before?
Only North Korea, which withdrew in 2003. Iran would be the second state to leave if the bill passes.
What happens if Iran leaves the NPT?
Iran would no longer be bound by IAEA safeguards. Its stockpile of 60%-enriched uranium, already beyond inspector access, would have no institutional check.
When will the Majlis vote on the NPT bill?
No date is set. The bill needs Speaker Mohammad Baqer Qalibaf's approval before it can even go to an open-session debate, let alone a vote.Source:
Does Iran's NPT bill satisfy the treaty's Article X withdrawal requirement?
Not yet. Article X requires formal notice to all other treaty parties and the UN Security Council, three months before withdrawal takes effect. The Majlis bill is domestic legislation authorising that step; as of 20 September 2026 it has not even been scheduled for a floor vote, so no Article X notice has been given.Source: NPT Article X
