Under the Vienna Convention on Diplomatic Relations, a diplomatic envoy is immune from criminal jurisdiction of the receiving State for all acts, whether private or official, and hence he cannot be arrested, prosecuted and punished for any offense he may commit, unless his diplomatic immunity is waived. On the other hand, officials of international organizations enjoy ―functional immunities, that is, only those necessary for the exercise of the functions of the organization and the fulfillment of its purposes. (G.R. No. 125865)
