Factual background
(This question handles the same topic but asks different questions.)
Background: on November 22, 2024, the International Criminal Court (ICC) published arrest warrants for various individuals suspected of international law violations with respect to an ongoing conflict in Gaza/Lebanon. Such individuals include the current prime minister of Israel and members of his cabinet.
The French ministry of Foreign Affairs published today (November 27, 2024) the following statement (English translation by me, there does not seem to be an official translation at the moment):
La France respectera ses obligations internationales, étant entendu que le Statut de Rome exige une pleine coopération avec la Cour pénale internationale (CPI) et prévoit également qu’un État ne peut être tenu d’agir d’une manière incompatible avec ses obligations en vertu du droit international en ce qui concerne les immunités des États non parties à la CPI. De telles immunités s’appliquent au Premier ministre Netanyahou et aux autres ministres concernés et devront être prises en considération si la CPI devait nous demander leur arrestation et remise.
France will fulfill its international obligations, with the understanding that the Rome Statute demands full cooperation with the ICC, and also establishes that a State may not act in a manner incompatible with international law with respect to the immunity of States that are not party to the ICC. Such immunities apply to prime minister Netanyahou and other concerned ministers and must be taken into consideration if the ICC asked France to arrest and deliver them.
France is a party to the Rome Statue. Israel is not (nor is Lebanon). Palestine is, kind-of (see this footnote of the Wikipedia article for details).
Questions
What are the "immunities" described in the statement? Do they apply to specific persons (e.g. Netanyahou and high-ranking officials) or to all Israelis (or all nationals of a non-signatory state)?
Assume that somehow the French government is able (legally and practically) to arrest one of the requested persons. Is it under an obligation to do so?
(Answers for any country that is a party to the Statute of Rome are welcome.)
I am specifically not interested in:
- the canned answer that "international law is unenforceable" (sure, but let’s assume France tries to obey it);
- technical speculation as to whether French police forces could practically arrest any of the requested persons (assume it can easily and safely do so; for instance, suppose Netanyahou resigns all his offices, retires from politics and comes visit France on a holiday visa; he stays for an extended duration and his place of residence is published in the press)
- political speculation as to whether France should disobey international law due to circumstances such as its interests in the Middle East, its relationship with the US or whatever (I have an adequate supply of pundit drivel in my home newspapers).
My analysis
France has a duty to cooperate with ICC investigations (under article 86 and following). The French government may dislike the ICC decisions but (as long as it has not withdrawn from the Statute as provided therein) it is still bound by them.
Therefore, in my understanding, the French government (or French courts) does not have any legal leeway to question whether the ICC has jurisdiction over specific persons, for specific facts, whether the warrants were regularly issued and so on. The French government may grumble as loudly as it wants, but its hands are tied, it must execute the warrant. In particular, the ICC has already decided (by issuing the warrants) that Netanyahou and others are not immune from prosecution.
I find this hard to square with the foreign ministry’s statement that suggests France may not enforce the warrant if certain unspecified legal circumstances arise.
