INTRODUCTION
Diplomatic Immunity is one of the fundamental principles of international law. It makes sure that the official functions of a diplomat can be performed independently and without any intrusions coming from the receiving state. [1]The term diplomatic immunity refers to the immunity granted to diplomats from the civil, criminal, and administrative jurisdiction of the state, according to the Vienna Convention on Diplomatic Relations 1961.[2] The doctrine was not formulated for the benefit of the diplomats themselves, but to ensure that the diplomats could work effectively and had peacekeeping relations with other nations.
Even though diplomatic immunity has gained a lot of importance, it has become very controversial as well. For example, in high-profile cases where diplomats or individuals connected to diplomatic missions are accused of major misconduct, the victims unfortunately cannot obtain proper justice. The fatal shooting of British police officer Yvonne Fletcher in London outside the Libyan embassy is such a case.[3] Also in 2019, the death of Harry Dunn, which happened due to a road traffic accident involving Anne Sacoolas, gave way to a heated public debate regarding international law. [4]Whether international law struck a suitable balance between diplomatic protection and accountability. This article discusses the argument that while diplomatic immunity is essential for international diplomacy, there are some changes that can be made to improve accountability while not compromising the essential purpose of diplomatic immunity.
LEGAL FRAMEWORK
The Vienna Convention on Diplomatic Relations 1961 is the primary legal basis for diplomatic immunity and is regarded as a customary international law convention. [5]According to Article 29, a diplomat may not be arrested or detained in the host country.[6] Article 31 says that immunity from criminal jurisdiction of the state additionally permits immunity from the criminal jurisdiction of the receiving state. [7]These safeguards enable diplomats to carry out their responsibilities without political persecution.
Article 41 calls for diplomats to observe the laws and regulations of the State of which they are the representatives and shall not intervene in its internal affairs. [8]Article 9 allows the receiving State to designate a diplomat persona non grata and calls for the recall of the diplomat by the sending State.[9] The sending State may also expressly waive the immunity of the diplomat, in which case, legal proceedings may continue where appropriate, under Article 32. [10]These protections are in place but depend critically upon the cooperation of the sending State, which has no duty to waive immunity or prosecute the diplomat in question.
The Convention is given effect in the United Kingdom via the Diplomatic Privileges Act 1964[11]. Diplomats from the United Kingdom are normally immune from criminal and civil proceedings, subject to very limited exceptions, as detailed in Atkin’s Court Forms.[12] In this respect, British courts have limited jurisdiction over diplomats even in the case of serious criminal offences.
SIGNIFICANCE OF DIPLOMATIC IMMUNITY
The doctrine of diplomatic immunity is based on the principle of reciprocity. Foreign diplomats are given privileges by the states, and states expect that their diplomats will be treated the same way in other states. This is a mutually beneficial arrangement that helps to maintain peace and safety in diplomatic missions and relations in countries with unstable or unfriendly governments. The Vanderbilt Journal of Transnational Law suggests that a reduction in diplomatic immunity would leave diplomats around the world vulnerable to politically motivated prosecutions, which would have a negative impact on international diplomacy.[13]
In the International Court of Justice’s ruling on the United States Diplomatic and Consular Staff in Tehran (United States v Iran), diplomatic immunity was again emphasized.[14] The Court said Iran didn’t protect the premises and people of the United States Embassy in Tehran in violation of the Vienna Convention.[15] The court also emphasized the role of diplomatic law in ensuring peaceful relations between the States and stated that it is one of the bases of the international legal order.
ACCOUNTABILITY AND ABUSE OF DIPLOMATIC IMMUNITY
Diplomatic immunity is necessary for diplomacy to be effective but has often been criticised for allowing diplomats to avoid accountability when they are accused of serious misconduct. When people feel they are being protected from prosecution, they begin to feel that diplomats are above the law, and this is a matter of public concern.
The most obvious in the UK is the shooting death of Yvonne Fletcher outside the Libyan Embassy in London in 1984. In a demonstration, shots were fired from within the embassy, killing Fletcher and injuring others.[16] Diplomatic immunity meant that the British had no right to go into the embassy or prosecute responsible parties. Rather, the United Kingdom cut ties with Libya and sent Libyan diplomats back home. These actions were affected in accordance with international law, but not for the immediate criminal justice of the victim.
One of the more recent ones is Harry Dunn’s death in 2019, after a road traffic accident involving Anne Sacoolas. [17]The claim of diplomatic immunity sparked considerable public and political debate, with some doubting whether immunity should be extended to actions unrelated to official diplomatic activities. This case eventually went to a U.S. court, but it illustrated the difficulties that receiving States have in exercising immunity.
This is a conflict between diplomatic protection and accountability as reflected in academic opinion. However, while there are abuses of diplomatic immunity, it is discussed that the doctrine is a “necessary evil” because the advantages to international relations far outweigh the number of cases where there is misbehaviour.[18] In the same way, authors like Hazel Fox say that the waiver of immunity and the declaration of persona non grata are hardly effective measures to protect domestic workers exploited by diplomats because the sending State bears no legal responsibility to waive immunity, nor to prosecute the diplomat once recalled. [19] More recent scholars also point to the exploitation of domestic workers by diplomats and how victims of such exploitation are often denied effective legal remedies owing to Article 31 of the Vienna Convention. [20]
The principle of immunity is also discussed by the International Court of Justice in the Arrest Warrant of 11 April 2000 (Democratic Republic of the Congo v Belgium). The case was not for the immunity of a serving Foreign Minister, but a diplomat; the Court repeated that immunity is procedural rather than substantive. [21] That is, when immunity exists, other courts lack jurisdiction, but when immunity does not exist, the criminal responsibility of the person does exist. However, that does not always mean that the sending State will investigate or prosecute its own officials when holding them accountable.
REFORM
Diplomatic immunity is not to be eliminated, but enhanced within its framework, through international law. The adoption of Article 32 of the Vienna Convention waivers of immunity would increase public confidence in the effective investigation and prosecution of serious offences, as well as in the diplomatic application of the doctrine through greater cooperation between States.[22] Academic commentators have also suggested compensation for victims and a more limited understanding of immunity when alleged wrongdoings do not have anything to do with diplomatic duties. [23]
CONCLUSION
To conclude, diplomatic immunity is an essential part of international law as it allows diplomats to carry out their duties without being inhibited or affected by politics. The judicial rulings of the International Court of Justice reaffirm the fact that the principle is essential to maintain peace in international relations. But the current system fails to provide victims with effective remedies in some instances, such as Yvonne Fletcher and Harry Dunn. The essence of diplomatic immunity should therefore remain a fundamental part of international law, but with greater means to foster accountability and to make sure that immunity is a protection for diplomacy, not for impunity.
