Use of force in international law Click to view full image

Legal provision

  • Article 2(4) of the UN Charter

    • Prohibits the use of force against the territorial integrity or political independence of any state.

    • Considered a cornerstone norm of international law.

Permissible exceptions

  1. Self-defence (Article 51)

  2. UN Security Council authorisation

U.S. justifications and their legal limits

Arguments advanced by the U.S.

  • Law enforcement operation to prosecute alleged criminals

  • Pre-emptive action against regional threats

  • Claims of illegitimacy of the Maduro government

Why these fail legally

  • Law enforcement across borders without consent violates sovereignty.

  • Expanded self-defence (anticipatory/pre-emptive) remains highly contested.

  • Humanitarian intervention without UN authorisation lacks legal backing.

  • Revival of the Monroe Doctrine is incompatible with modern international law.

Head of State immunity: Key legal principle

International Court of Justice precedent

  • International Court of Justice

  • Arrest Warrant Case (DRC vs Belgium)

Doctrine applied

  • Immunity ratione personae

    • Sitting heads of state enjoy absolute personal immunity from foreign criminal jurisdiction.

    • Applies irrespective of alleged crimes.

Effective control doctrine

  • Recognition by other states is irrelevant.

  • What matters is whether the government exercises effective control over territory.

  • Maduro administration satisfies this test.

Therefore, U.S. courts lack jurisdiction over the Venezuelan President.

International wrongs highlighted

  • Forcible abduction of a foreign national from sovereign territory

  • Trial before domestic courts without consent

  • Interference in internal affairs

  • Attempt to “run” or control another state’s governance

All constitute internationally wrongful acts.
