Diplomatic Privileges

Diplomatic privileges are the bundle of legal protections, exemptions, and courtesies extended to foreign envoys and their missions by the receiving state. Their modern codification rests on the Vienna Convention on Diplomatic Relations (VCDR), 1961, supplemented by the Vienna Convention on Consular Relations, 1963 for consular officers, who enjoy a narrower set of protections.

The core privileges include:

• Inviolability of the person (VCDR Art. 29): diplomatic agents may not be arrested or detained.
• Inviolability of mission premises, archives, and correspondence (Arts. 22, 24, 27), including the diplomatic bag.
• Immunity from criminal jurisdiction, and broad immunity from civil and administrative jurisdiction, of the receiving state (Art. 31).
• Fiscal privileges: exemption from most direct taxes, customs duties on official and personal-use imports, and social security obligations (Arts. 23, 33–36).
• Freedom of movement and communication within the receiving state (Arts. 26–27).

Privileges attach by function, not as personal favor — the rationale, expressed in the VCDR preamble, is ne impediatur legatio (that the mission not be impeded). They extend in varying degrees to family members, administrative and technical staff, and service staff. The sending state alone may waive immunity (Art. 32), and waiver must be express.

Abuse of privileges is policed primarily through the persona non grata mechanism (Art. 9), under which the receiving state may expel a diplomat without stating reasons. Persistent disputes — over unpaid parking fines, traffic incidents, or alleged espionage — recur but rarely override the regime, because every state is simultaneously a sending and receiving state and has reciprocal interests in maintaining it.

Privileges are distinct from diplomatic immunity (a subset focused on jurisdictional protection) and from state immunity, which shields the state itself rather than its representatives.
