In their final session before the March 20 New Year, 260 of the 290 members of Iran’s parliament have signed a statement demanding that all sanctions on the country be removed in the case of a nuclear deal. According to Mehr News Agency, the statement has three conditions:

• The removal of all sanctions at once, closing Iran’s nuclear file at the UN Security Council and returning it to a normal status is the first condition of a complete nuclear file.
• The preservation of the achievements and full rights of the nuclear rights of Iran based on Article 4 of the Non-Proliferation Treaty is the demand of a united Iran.
• In case of a violation of any of the agreements by the opposing side … the agreement becomes overruled and enrichment will take place at any level the country needs.

The statement is significant because if Iran and the five permanent members of the UN Security Council plus Germany (P5+1) agree to a comprehensive nuclear deal, Iran’s parliament would need to ratify additional protocols, which allow greater scrutiny for nuclear inspectors. But Speaker Ali Larijani said "cases that are at the National Security Council [such as the nuclear file] are authorized by the supreme leader [and] it's possible it may not reach parliament for ratifying." 

Still, most Iranian officials who call for “all” sanctions to be removed seem to be vague if they are referring to nuclear-related sanctions or all the sanctions that have been imposed on Iran by the P5+1 countries. Ayatollah Ali Khamenei, the supreme leader who has final say on the nuclear program, has also said that a nuclear deal must be a one-time deal rather than a multistep deal. This could be construed as relating to sanctions as well, though it’s uncertain.

Larijani, a former chief negotiator himself, in discussing parliament’s role, also said that if the negotiators reach a “good” deal, that parliament will ratify the nuclear deal. He didn’t explain what a good deal would look like but added: “If we don’t reach a comprehensive deal, it’s not the end of the world and we’re living our own lives now without a comprehensive agreement and we have other approaches if there is not an agreement.”
