User: Some person is saying that Mamdani can arrest Netanyahu because the ICC has an arrest warrant out for him.

Some person is saying that Mamdani can arrest Netanyahu because the ICC has an arrest warrant out for him. Please fact check this.

Assistant: Here are the facts, checked carefully:

Here are the facts, checked carefully:

1. The International Criminal Court (ICC) issued an arrest warrant for Benjamin Netanyahu (Prime Minister of Israel) on 21 November 2024, for alleged war crimes and crimes against humanity in the Gaza conflict. Jewish Telegraphic Agency

1. A U.S. politician, Zohran Mamdani (running for NYC Mayor), publicly pledged that if elected he would order the New York City Police Department (NYPD) to arrest Netanyahu if he visited New York City. The Guardian

- The United States is not a member of the Rome Statute, which governs the ICC. So U.S. federal law does not automatically require U.S. authorities to enforce ICC arrest warrants. The National News

• Even if the NYC Mayor ordered an arrest, in practical and legal terms it would likely not be enforceable if federal government or U.S. law does not cooperate. Legal experts deem such a move by a mayor as a “publicity gesture” rather than an actionable order. The National News
• The ICC’s warrant obliges ICC member states that have the treaty to implement it. The U.S. is not among them; therefore enforcement in U.S. territory is legally unsupported. Wikipedia

- Yes: there is a valid ICC warrant for Netanyahu.

• No: the claim that “Mamdani can arrest Netanyahu” (in the sense that it is legally enforceable through U.S./NYC law) is false. It is not legally plausible under current U.S. federal and international law.
• The vow by Mamdani is a political statement, not a juridical guarantee.

If you like, I can check which countries are required to arrest Netanyahu under the ICC warrant and whether he has travelled into one of those jurisdictions.

He also cannot do something which would interfere with the federal governments reserved rights in foreign affairs correct?

Assistant: Correct.

Correct. Under U.S. constitutional law, foreign affairs are a federal power, not a municipal or state power. A mayor cannot take actions that intrude into or contradict the federal government’s exclusive authority in this domain.

Key points:

1. Foreign affairs are reserved to the federal government - U.S. Constitution, Article I (Congress) and Article II (President) assign diplomacy, recognition of foreign governments, treaty enforcement, and international law to the federal level. - The Supreme Court has repeatedly held that states and municipalities cannot create their own foreign policy or take actions that meaningfully interfere with federal foreign policy.
2. Local governments (including mayors) have no lawful authority to enforce or ignore international arrest warrants - The ICC warrant has no force in the U.S. unless implemented by federal statute (which it has not been; the U.S. is not party to the Rome Statute). - Therefore, a mayor cannot legally direct police to arrest a foreign head of state based solely on an ICC warrant.
3. Attempting to arrest a sitting head of government for foreign-policy reasons would directly conflict with federal authority - Such an action would be viewed as: - Interference in foreign relations - Possibly a violation of executive privilege in diplomacy - A trespass against federal supremacy under the Supremacy Clause (Article VI)
4. NYPD is a municipal police force - They have authority only over violations of state or local law. - An ICC warrant has no automatic standing in New York criminal law. - Without a federal warrant or federal request, NYPD cannot lawfully act.

Conclusion

Yes, the mayor is constitutionally barred from taking actions that would interfere with the federal government’s foreign affairs powers. A municipal arrest of Netanyahu on an ICC warrant, without federal authorization, would be unlawful, unenforceable, and overridden immediately by federal supremacy.

If you want, I can provide the exact Supreme Court case references that establish these principles.

If a mayor attempted to order a municipal police force to arrest a foreign head of government based on an ICC warrant without federal authorization, the federal government has several clear legal mechanisms to stop it immediately:

1. Federal Preemption / Supremacy Clause

The U.S. Constitution (Art. VI) gives federal law supremacy over state and municipal actions in matters of foreign affairs. The Department of Justice could seek an emergency injunction in federal court to block the mayor’s order. A federal judge would almost certainly issue:

• Temporary Restraining Order (TRO) → same day
• Preliminary Injunction → within days The order would prohibit NYPD from acting.

2. Direct Federal Intervention via U.S. Marshals

If the local government attempted to proceed despite a court order, the federal government could:

• Deploy U.S. Marshals to override or physically prevent the action
• Take custody of the protected individual (Netanyahu) under diplomatic protection laws

This is similar to federal enforcement seen in historical desegregation cases when local authorities defied federal orders.

3. Criminal Exposure for the Mayor or Local Officials

If the mayor or police leadership knowingly defied a federal injunction, they would be exposed to:

| Charge | Basis | | ------------------------------------------------------------ | ----------------------------------------- | | Contempt of Court (civil or criminal) | Defying a federal court order | | Deprivation of Rights Under Color of Law (18 U.S.C. § 242)** | If the arrest lacked legal authority | | Interference with Federal Duties (18 U.S.C. § 111 or §1505) | Obstructing federal diplomatic protection |

These are real, enforceable criminal offenses.

4. Removal from Office (State Mechanisms)

New York State law allows removal of a mayor for:

• Malfeasance
• Willful misconduct
• Refusal to follow court orders

The state governor or state courts could remove the mayor.

5. Diplomatic and Treaty Protections

Even beyond ICC issues:

• Foreign heads of government have recognized inviolability under customary international law while on official visits.
• The federal executive branch is responsible for enforcing that.

If the mayor attempted to override that, federal authority would supersede him instantly.

Summary

If a mayor attempted to arrest Netanyahu on an ICC warrant:

• Federal courts would block it immediately.
• U.S. Marshals could physically intervene.
• The mayor and police leadership could face criminal charges.
• The mayor could be removed from office.

There is no legal scenario where a U.S. mayor could carry out such an arrest and have it stand.

If you want, I can now provide the specific Supreme Court precedents that establish these limits (e.g., Zschernig v. Miller (1968), American Insurance Ass’n v. Garamendi (2003)).
