City Comptroller Rejects Local Jurisdiction Over Netanyahu
The discussion follows comments made by Mamdani, who suggested that as a leader, he would consider honoring an International Criminal Court (ICC) warrant for the Prime Minister’s arrest.
Ambassador to the United Nations Mike Waltz emphasize that local law enforcement lacks the jurisdiction to execute such an arrest, as federal immunity and diplomatic protections supersede municipal authority.
Constitutional Barriers to Municipal Intervention
The proposition of a local arrest for a visiting head of state faces significant federal and international legal hurdles.
Former prosecutors note that any attempt by local police to detain a foreign head of state based on an ICC warrant would likely violate federal statutes. Furthermore, the United States is not a party to the Rome Statute, the treaty that established the ICC, meaning the court’s warrants carry no domestic legal weight within the U.S. judicial system.
Diplomatic Immunity Under UN Headquarters Agreement
Visiting heads of state are protected by the UN Headquarters Agreement, which dictates the terms under which the United Nations operates within New York City. This agreement, along with established principles of international law, grants diplomatic immunity to heads of state, shielding them from arrest or detention by local authorities while they are in the country for official business.

U.S. Ambassador to the United Nations Mike Waltz dismissed the prospect of such an arrest as legally impossible. According to comments reported on the platform X, Waltz characterized the suggestion as "pure political theater," citing the lack of U.S. participation in the Rome Statute and the supremacy of federal authority over local municipal actions.
The ICC Conflict and Local Political Tensions
The ICC Prosecutor has sought warrants for various leaders involved in the conflict, alleging war crimes. Israel has consistently rejected these allegations, stating that its military operations comply with international law and that it does not recognize the court’s jurisdiction in the matter.
While municipal leaders may express positions on international affairs, the execution of legal mandates regarding foreign dignitaries remains strictly controlled by the U.S.
