Nicolás Maduro and his wife Cilia Flores have asked a US judge to dismiss the drug trafficking indictment against them. Their argument is head-of-state immunity: that as the leader and first lady of a foreign state, they cannot be prosecuted in an American court.

Maduro was captured by the United States in January and is being held for trial. The motion is the first substantial legal test of how he came to be in an American courtroom.

What head-of-state immunity is

Customary international law recognises that a serving head of state is immune from the criminal jurisdiction of another state’s courts. The rationale is functional rather than personal: states are sovereign equals, and one cannot sit in judgment over another’s leader without collapsing that principle.

The immunity attaches to the office, not the individual, and it is generally understood to end when the officeholder leaves office — at which point immunity for private acts falls away, though a narrower immunity for official acts may persist.

In American practice, the executive branch has historically had substantial influence over whether a foreign leader is recognised as immune, because courts have deferred to State Department suggestions of immunity.

Why that is complicated here

The defence argument runs into a fact the prosecution will rely on: the United States has not recognised Maduro as Venezuela’s legitimate president for years, having disputed the 2024 election result. On the US government’s own position, he was not a head of state at the relevant time, and immunity that depends on an office he is not recognised as holding does not arise.

The defence’s answer is that immunity in international law follows effective control of a state, not another government’s recognition decisions — and that allowing one country to strip immunity by declining to recognise a leader would let any state prosecute any foreign head of state it disliked.

That is a serious argument, and it is why the motion is worth reporting rather than dismissing as a formality. It is also, on the current state of US law and given who decides recognition questions, an argument that faces long odds in an American court.

Whatever a judge decides will be about immunity, not about whether the trafficking allegations are true. Those remain allegations, and Maduro has denied them.

The part nobody is litigating

There is a separate question the motion does not squarely raise, and courts have historically declined to entertain: whether it matters how a defendant came to be in the jurisdiction.

American courts have long held that a defendant’s presence, however irregularly obtained, does not defeat jurisdiction. That doctrine has been criticised for a century by scholars who argue it rewards abduction, and it has been reaffirmed anyway. Anyone expecting the circumstances of Maduro’s capture to end the prosecution should read that line of authority first.

What is happening in the meantime

While the case proceeds, the country Maduro governed is being reorganised commercially. Yesterday Chevron announced it would invest more than seven billion dollars in Venezuela and more than double its production there, and the US Energy Secretary announced energy agreements at Miraflores alongside the interim president — as we reported in our piece on the Chevron expansion, and earlier in the deal covering 65 billion barrels of reserves.

The sequencing is worth stating without editorialising: a head of state was captured, a government that did not stand for election is signing long-term resource agreements with the state that captured him, and the criminal case against him is being litigated in that same state’s courts.

Supporters of the policy say the trafficking charges are serious, long-standing and independent of the oil arrangements. Critics say the two cannot be separated. Both will point at the same docket.

What to watch

Whether the State Department files any statement of interest on the immunity question. If it does, the court will almost certainly follow it, and the executive branch will have decided the issue rather than the judge.
