After Versailles, Iran Faces Its Own Ratification Gap

President Masoud Pezeshkian’s signature on the US-Iran memorandum of understanding at Versailles places the Iranian executive’s name on a document the supreme leader’s office has not endorsed in writing and the Iranian parliament has not been asked to ratify. The structural risk the desk traced on the US side — an executive-only instrument routed around the Senate — has a mirror on the Iranian side, and the Versailles signing made it operational.

The thesis is simple. The Geneva framework now exists as an executive-to-executive instrument on both sides. Neither legislature has been brought in. Neither constitutional principal of last resort — the US Senate, Iran’s supreme leader — has formally endorsed it. The durability of the document past the political moment that produced it will depend on whether that gap is closed inside the 60-day window, or whether it is allowed to stand.

The Iranian architecture

Iran’s foreign-policy ratification chain is not a direct analogue of the US Senate’s advice-and-consent role, but it carries comparable structural weight. The Majlis under Article 77 of the Iranian constitution must approve international treaties; whether a memorandum of understanding rises to that bar is a question the Guardian Council historically arbitrates. The supreme leader’s office sits above the Majlis on national-security questions and has, in practice, decided which agreements run and which do not — the Khamenei red line on uranium stockpiles inside the same negotiating track is the recent example of how that authority is exercised.

What Pezeshkian signed at Versailles is therefore an executive instrument carrying his name and the prestige of the office, but not, by itself, the binding force of an Iranian commitment. The Iranian parliament has not voted on the text. The Guardian Council has not reviewed it. The supreme leader has not endorsed it, contradicted it, or acknowledged it publicly since the signature appeared.

That silence is the same diagnostic variable the desk’s Thursday note on Tehran’s posture flagged in a different register. Khamenei’s office had declined to endorse the “not final” framing Trump applied to the document. The Versailles signature has not changed that posture. If anything, it has sharpened the question: the supreme leader has now had a signed Iranian executive instrument in front of him for several hours and has not spoken on it.

The Majlis track

Parliament Speaker Mohammad Bagher Ghalibaf, who signed the Geneva instrument earlier in the week alongside Vice President JD Vance, used Thursday to take a public position that puts daylight between the executive’s framing of Hormuz and the parliament’s. His statement that Iran will charge transit-services fees in the strait after a 60-day window is the first principal-level Iranian framing of the deal’s limits since the Versailles signature.

Ghalibaf’s intervention does two things at once. It anchors a parliament-level read of the document that differs materially from the executive’s, and it does so without the Majlis having held a ratification vote. The substance is now in dispute; the procedural authority to bind Iran to the substance has not been invoked. A future Majlis floor vote on the Hormuz toll regime — should one come — would be the legislative branch retroactively shaping what Pezeshkian signed at Versailles.

That sequence is the inverse of the US legislative track, which is being routed around. On the Iranian side the legislature is being routed around at the signing stage but reserves the operational tools to define the instrument’s domestic meaning afterwards through parliamentary action on tolls, port fees, and IRGC operational guidance. The two sides are running parallel executive-only signing tracks with parallel legislative-side leverage held in reserve.

The Khamenei question

The single highest-stakes ratification question is whether Khamenei’s office endorses the Versailles signature on the record before Friday’s Geneva ceremony — or after it. Endorsement closes the question on the Iranian side definitively and converts the dispute over the framework’s status into a constitutional one in which the Iranian executive’s signature carries the weight of supreme-leader-level commitment. The cost of that move is the same as it would be for any binding sovereign commitment: it forecloses Tehran’s own flexibility on subsequent rounds, on the missile-programme follow-on the G7 endorsed, and on the verification track.

Continued silence is the more likely path. It allows Khamenei to read the framework’s performance over the 60-day window before deciding whether to attach the office’s authority to it. It also leaves Iran’s principal of last resort with the option of repudiating the Versailles signature without breaking constitutional process, in the way the 2018 US withdrawal repudiated the JCPOA without breaking US constitutional process.

A public Khamenei position rejecting the framework — at the high end of the response set — would be the cleanest signal that the Versailles signature does not bind Iran in any operational sense. Nothing in Thursday’s silence so far suggests that move is in motion. The base case is the middle path: Khamenei withholds endorsement, the Majlis stays in reserve, and the framework runs on executive credibility for as long as the operational picture supports it.

What this means for Friday

The Friday Geneva ceremony, if it proceeds, will not change the Iranian ratification posture. A second signing layer at the protocol level does not generate constitutional weight that the principal signing did not produce at Versailles. Whether the ceremony is held as scheduled, downgraded to a formality, or folded into the Versailles event, the Iranian side will arrive at the weekend with an executive-signed instrument, an unendorsed supreme-leader file, and a Majlis that has staked out a position on the deal’s most operationally consequential question without holding a vote.

The Geneva framework was always going to be tested operationally on Hormuz, on Lebanon, and on verification. It is now also going to be tested constitutionally on both sides — and the side where Khamenei’s silence is the diagnostic variable is the side the desk is watching closer through the weekend.
