Definition and Legal Foundations of Diplomats
A diplomat is an official representative of a state, who acts on the basis of international law in international relations. Diplomats, as members of the diplomatic service, are entrusted with maintaining intergovernmental relations, particularly political communication, negotiations, and the protection of their home state’s interests in the host state. The legal status, privileges, and immunities of diplomats are governed by numerous supranational norms and national regulations.
Legal Definition and Duties of Diplomats
Legal Definition and International Standardization
The concept of a diplomat is legally anchored and defined primarily in the Vienna Convention on Diplomatic Relations of April 18, 1961 (VCDR). Under this agreement, diplomats are mainly understood to be members of a diplomatic mission, namely the head of mission (such as ambassador or envoy) and the diplomatic staff (Art. 1 lit. a, b VCDR). Accreditation is carried out by sending a state subject to a foreign state and its acceptance by the host state.
Scope of Responsibilities
Diplomats perform the following functions (see Art. 3 VCDR):
- Representation of the home state in the host state
- Protection of the interests of the home state and its nationals in the host state
- Conducting negotiations with the government of the host state
- Gathering information within the legal framework
- Promotion of friendly relations between states
Accreditation and Exercise of Diplomatic Functions
Procedure for Deployment and Accreditation
For the lawful exercise of their function, the diplomat requires formal accreditation. The assignment is made by the sending state, for example by letter of credence, and requires the consent (agrément) of the host state. The diplomat acquires official status only upon presentation of the letter of credence to the head of state or government.
Termination of Diplomatic Activity
Diplomatic status may end by recall, termination of the mission, completion of a new mandate, or by a declaration of persona non grata (Art. 9 VCDR) by the host state.
Rights, Privileges, and Immunities of Diplomats
Diplomatic Immunity
The central legal peculiarity of diplomats is their immunity. This is comprised of several aspects:
Personal Immunity
Diplomats enjoy complete immunity from criminal jurisdiction of the host state (Art. 31 VCDR). Immunity covers both official and private acts.
Immunity from Civil and Administrative Jurisdiction
Extensive immunity rights also exist with respect to civil and administrative proceedings, with a few exceptions such as private transactions unrelated to official duties (Art. 31 para. 1 lit. c VCDR).
Exemption from Taxes and Customs Duties
Diplomats are generally exempt from taxes, duties, and customs obligations (Art. 34 et seq. VCDR), insofar as these are related to official tasks.
Inviolability of Person and Premises
The person of the diplomat is inviolable (Art. 29 VCDR); arrest or any other restriction is prohibited. The same applies to the immunity of residential and office premises, as well as diplomatic correspondence (Art. 22–24 VCDR).
Obligations of the Diplomat
Despite comprehensive rights, diplomats have the duty to respect the laws and regulations of the host state (Art. 41 VCDR) and not to interfere in the internal affairs of the host state.
Distinction from Other Status Groups
Consular Officers
Consular officers are subject to less extensive privileges and immunities than diplomats. The relevant rules are set out in the Vienna Convention on Consular Relations (VCCR) of 1963.
Special Envoys and International Organizations
Representatives of international organizations or special envoys may also possess similar, yet specifically regulated, special rights and immunities, defined for example by the Headquarters Agreement or the Convention on the Privileges and Immunities of the United Nations.
Abuse and Limitations of Immunity Rights
A diplomat’s immunity must not be abused for private purposes. In cases of serious violations, the host state may declare the person concerned ‘persona non grata’ and terminate their stay. The sending state may also independently waive immunity (Art. 32 VCDR).
Significance and Current Developments
Diplomatic law serves to ensure undisturbed intergovernmental communication and supports stable foreign relations worldwide. In recent years, there have been discussions about adjusting immunity rules, particularly in regard to combating crime, terrorism, and human rights violations, while the principle of mutual recognition continues to be a central tenet of diplomatic engagement.

Frequently Asked Questions
What legal frameworks govern the immunity of diplomats?
The international legal basis for diplomatic immunity is primarily the Vienna Convention on Diplomatic Relations (1961, VCDR), which has almost universal application. Under this, diplomats enjoy immunity from criminal, civil, and administrative jurisdiction of the host state. This immunity covers both the diplomat’s person (personal immunity) and their diplomatic correspondence and mission premises. It includes the right not to be arrested or detained and protects against any form of judicial or administrative action by host state authorities, unless in cases of particularly serious crimes for which the sending state expressly lifts the immunity. The Vienna Convention and supplementary bilateral treaties are decisive for the specific configuration. Exceptions and limitations exist, for example in connection with private transactions outside official duties. Violating diplomatic immunity regularly leads to international consequences and may even spark diplomatic conflicts.
What rights do diplomats have regarding the exercise of their office in the host state?
According to international law, diplomats have a variety of special rights in the host state. These include, in particular, the right of free access to all state authorities in the host country required for the fulfillment of their duties, and the right to represent the interests of the sending state and its nationals. Diplomatic mail and communication are inviolable and may not be opened or withheld, nor may the offices and residences of diplomatic representatives. These rights are conditional on the diplomat’s activities complying with the provisions of the Vienna Convention and not constituting interference in the internal affairs of the host state. Violations may result in a declaration of persona non grata and expulsion.
Under what circumstances can a diplomat be expelled?
The legal basis for the expulsion of a diplomat is governed by the 1961 Vienna Convention. According to it, the host state may, at any time and without justification, declare a diplomat to be an undesirable person (persona non grata). In this case, the sending state is obliged to recall the person concerned or terminate their functions. The decision of the host state is not subject to appeal and need not be legally substantiated in individual cases. If the diplomat remains in the country despite expulsion, he loses his diplomatic status and thus the associated protections and immunities, which may lead to criminal prosecution.
What is the criminal responsibility of diplomats in Germany?
According to German law and on the basis of international agreements, diplomats enjoy immunity from criminal jurisdiction as long as they are in office. The Federal Republic of Germany applies the Vienna Convention on Diplomatic Relations directly. If diplomats violate German law, only the sending state can waive immunity to allow criminal prosecution. If this does not happen, Germany may only initiate diplomatic measures or declare the person persona non grata. Immunity generally does not extend to nationals of the host state or family members, unless they themselves possess the status of a mission member.
What does the protection of diplomatic premises and documents include?
Diplomatic premises such as embassies and consulates are specially protected under Article 22 of the Vienna Convention. They are inviolable and may not be entered, searched, or seized by host state authorities unless the mission chief consents. The documents and archives of a diplomatic mission are protected at all times and regardless of location. The obligation of the host state also extends to taking appropriate measures to protect the mission and its premises from attacks and damage. Enforcement actions, searches, or secret surveillance measures are strictly prohibited.
Are diplomats subject to employment or tax obligations in the host state?
Diplomats are generally exempt from the labor jurisdiction and employment obligations of the host country in the course of their official duties. They also enjoy extensive tax privileges: under the Vienna Convention, they are exempt from taxation on their official emoluments, and usually from income tax, property tax, and other direct taxes, provided that the income derives solely from diplomatic activity. However, there are exceptions, e.g., for private employment or real estate transactions. Exemption from indirect taxes (such as value-added tax) is generally limited to certain goods and services and must comply with the legal provisions of the host state.
What happens to a diplomat’s legal status after the end of their diplomatic function?
When a diplomat’s mandate ends, such as after recall, expulsion, or expiration of accreditation, their diplomatic status and immunities under the Vienna Convention generally expire upon official notification to the host state. For certain acts carried out in the course of official duties, a so-called functional immunity remains, meaning these acts cannot continue to be prosecuted. For private acts committed after leaving office, however, immunity no longer applies. Retroactive prosecution is then permitted only for such acts that were not performed in the exercise of official functions.
