A DIPLOMATIC agent enjoys immunity from the criminal jurisdiction of the receiving state, according to Article 31 of the Vienna Convention on Diplomatic Relations signed in 1961.
But the immunity of a diplomatic agent from the jurisdiction of the receiving state does not exempt him from the jurisdiction of the sending state.
A diplomatic agent is also not obliged to give evidence as a witness.
A diplomat also enjoys immunity from civil and administrative jurisdiction, except for:
A real action relating to private immovable property situated in the territory of the receiving state, unless he holds it on behalf of the sending state for the purposes of the mission.
An action relating to succession in which the diplomatic agent is involved as executor, administrator, heir or legatee as a private person and not on behalf of the sending state.
An action relating to any professional or commercial activity exercised by the diplomatic agent in the receiving state outside his official functions. Inquirer Research
