Parliament presidium spokesperson Abbas Goudarzi said the three-priority plan will be reviewed immediately without waiting in line, with Guardian Council members present to rule on its conformity with Islamic law and the constitution.
The draft, put forward by members of the national security committee, could see both general principles and details voted on the same day.
Tehran is weighing its options after Britain, France and Germany triggered the “snapback” mechanism last month to restore UN sanctions, citing Iranian breaches of the 2015 nuclear deal.
Officials have sent mixed signals: some lawmakers insist parliament can pass the measure on its own, while former nuclear chief Ali Akbar Salehi said such a decision lies with Supreme Leader Ali Khamenei.
The debate comes as Foreign Minister Abbas Araghchi said Iran will not return to pre-war negotiating terms after June’s conflict with Israel.
“It is not the case that after the war, we would just return to the negotiating table and as you call it ‘business as usual,’” he said on Saturday, though he added that indirect exchanges with Washington and talks with Europeans continue.
Araghchi also said Iranian diplomats in Vienna were “very close” to reaching a new framework of cooperation with the International Atomic Energy Agency, in line with a law passed by parliament.
Iran’s envoy in Vienna confirmed that the third round of technical talks with the IAEA had focused on drafting guidelines for safeguards implementation following strikes on nuclear sites.
