Definition

In plain language

When a foreigner is arrested, the local authorities must tell the person they may contact their consulate. If the person asks, the authorities must inform the consulate without delay.

Academic definition

Article 36(1)(b) of the 1963 Vienna Convention on Consular Relations requires the receiving State to inform the consular post without delay if a national is arrested, committed to custody or detained, when the person so requests, and to inform the person of these rights without delay. In LaGrand (2001) the ICJ held that Article 36 creates individual rights and that failure to inform the detainees was a breach, a finding repeated in Avena (2004). The procedure is therefore a concrete operational step through which the broader consular assistance regime is triggered.

Context

Legal effect: Binding

Scope

Covers the step of informing the person and the consulate after arrest; the wider set of communication and access rights under Article 36 is treated in 'Consular Notification Rights', and diplomatic protection claims are separate.

Legal context

VCCR Article 36(1)(b) and Article 36(2), which requires that national law give full effect to the rights; the Optional Protocol of 1963 gives the ICJ compulsory jurisdiction over disputes about the Convention between parties. Some bilateral consular conventions require mandatory notification regardless of the detainee's request.

Diplomatic context

Failure to notify has led to diplomatic protests and ICJ cases, particularly in death penalty cases, and States issue guidance cards for police to ensure compliance.

Institutional context

Carried out by police, prison and immigration authorities, supervised by foreign ministries, and enforced where necessary by the ICJ.

Historical context

The rule was codified in 1963, and LaGrand in 2001 was the first ICJ judgment to treat it as an individual right.

Why it matters

Early notification lets consular officers arrange legal help and monitor treatment, which can affect the fairness of the whole proceeding.

Usage

Register: Legal

Usage note

Say 'consular notification' for the act of informing and 'consular access' for the right to visit and communicate with the detainee.

Example

Police informed the detainee of his right to consular notification and called the embassy at his request.

Example scenario

A tourist from State A is arrested in State B. The arresting officers read a card explaining consular notification, the tourist asks for the consulate to be told, and within hours a consular officer calls to arrange a lawyer.

Common misuse

Assuming that notification is optional or must wait until charges are filed; the Convention requires it without delay on request.

Not to be confused with

  • Consular access
  • Diplomatic protection
  • Notification of treaty actions
