Following the announcement by the E3 (France, Germany, and the United Kingdom) to trigger the snapback mechanism on sanctions against Tehran, Iran’s Parliament has drafted and submitted an emergency bill proposing a full withdrawal from the Nuclear Non-Proliferation Treaty (NPT). 

Hossein-Ali Haji-Deligani, Deputy Chairman of the Article 90 Committee of Iran’s Parliament, confirmed that the bill will be uploaded to the parliamentary system on the following day and subsequently reviewed in an open session.

“As we had previously stated, these countries were already implementing the consequences of the snapback mechanism, including sanctions against us. There is nothing new in this.” Haji-Deligani told Iran's Tasnim.

He further stated that the steps taken were “the most minimal response by Parliament to the recent action of the European countries, and further regret-inducing measures are also on the agenda.”

Deputy chairman calls for decisive action

The proposed legislation comes amid growing frustration in Tehran over the West’s repeated failure to honor agreements and ease pressure on Iran. Haji-Deligani noted that Iran’s Parliament is determined to pursue a firm and deterrent course of action.

According to the lawmaker, the activation of the snapback mechanism effectively reinstates previous sanctions but introduces no new developments. Nonetheless, he emphasized that Iran’s response would be strategic and assertive.

Criticizing continued dialogue with Western countries, Haji-Deligani asserted, “Given what these three countries have done, negotiations with them are now meaningless. Dialogue will only embolden them."

“We witnessed that during negotiations with the arrogant US, a brutal war was launched against our country by Israel, and the US bombed our peaceful nuclear sites,” he added. “Our people clearly know that talks with these countries have brought nothing but more pressure. Therefore, all dialogue must be suspended until these countries abandon their double standards.”

The emergency bill signals a potential turning point in Iran-E3 talks and highlights a significant policy shift in Tehran’s approach to its nuclear file. The move could impact the broader framework governing the Iran nuclear program and regional diplomacy.

Iran vows response

Iran’s Foreign Ministry confirmed on Thursday that France, Britain, and Germany have formally notified Tehran of their decision to trigger the "snapback" mechanism to reimpose United Nations sanctions under the 2015 nuclear deal.

Foreign Minister Abbas Araghchi condemned the measure as "illegal and unjustified," warning that Tehran would respond "appropriately to protect and guarantee its national rights and interests."

In a phone call with his French, British, and German counterparts, Araghchi urged them to "appropriately correct this wrong decision in the coming days." He stopped short of detailing possible retaliatory steps but hinted that the E3 risk being excluded from any future negotiations on Iran’s nuclear program.

The E3 action came just days after Iranian and European diplomats held a second round of talks in Geneva, billed as a last chance to salvage engagement before the October deadline for invoking the snapback clause.

The discussions collapsed without "tangible commitments," according to European officials, who claim that Tehran’s ongoing breaches of enrichment limits left them with no choice but to act. It is noteworthy that the E3 had failed to uphold their commitments in accordance with the JCPOA after the US unilaterally left the agreement in 2018.
