Definition

In plain language

A consular courier is the person who carries a consulate's official bag. The host State must protect the courier, who may not be arrested or detained while carrying out the task.

Academic definition

Article 35(5) of the 1963 Vienna Convention on Consular Relations provides that a consular courier must carry an official document indicating status and the number of packages constituting the bag, is protected by the receiving State in performing functions and enjoys personal inviolability, including freedom from arrest or detention in any form. Article 35(6) allows States to appoint ad hoc consular couriers, who enjoy the same protection only until they have delivered the bag to the consignee. The regime is parallel to the diplomatic courier under Article 27 VCDR and was further studied in the ILC's 1989 draft articles.

Context

Legal effect: Binding

Scope

Covers the person carrying the consular bag; the bag itself is addressed under 'Consular Bag', and a diplomatic courier is covered separately.

Legal context

VCCR Article 35(5) and (6); the courier must hold a document stating status and number of packages, and the protection ends on delivery when an ad hoc courier is used. Captains of ships or aircraft entrusted with the bag are not couriers but may be treated under Article 35(7).

Diplomatic context

Couriers cross borders with sealed bags and presentation of the courier letter, and disputes arise when officials question the status of a person or the contents of the bag.

Institutional context

Appointed by foreign ministries and consular posts, with customs and border officials expected to recognise the courier's document.

Historical context

Couriers carried official correspondence long before codification, and the regime for consular couriers was written into the 1963 Convention.

Why it matters

Protection of the courier is what allows confidential consular communications to cross borders safely.

Usage

Register: Formal Diplomatic

Usage note

Use 'consular courier' for the person and 'consular bag' for the package, and note that ad hoc couriers lose protection after delivery.

Example

The consular courier showed the document certifying the number of packages in the bag.

Example scenario

A courier from State A's consulate arrives at an airport in State B with three sealed packages and an official letter. Border officials check the document, record the packages and allow the courier through without detaining them.

Common misuse

Treating any person carrying a package for a consulate as a consular courier; the person needs an official document stating the status.

Not to be confused with

  • Diplomatic courier
  • Consular bag
  • Captain entrusted with a bag
