Diplomatic Immunity as a Loophole for Impunity in International Conflicts: A Normative Study of the Russia–Ukraine Conflict and the Urgency of International Legal Reform

Abstract

This study examines the 1961 Vienna Convention on Diplomatic Relations, which codified the system of diplomatic immunity historically designed to ensure the effective performance of diplomatic functions under stable inter-state conditions. However, the increasing intensity of international armed conflicts, particularly the Russia–Ukraine conflict since 2022, has exposed a fundamental vulnerability within the system, namely the absence of an adequate accountability mechanism when diplomatic immunity is abused by diplomatic officials. This research aims to analyze the normative gap within the 1961 Vienna Convention that potentially allows diplomatic immunity to function as an instrument of impunity in situations of international conflict, while also formulating the direction of international legal reform required to address such issues. This research employs a normative legal method using three approaches: the statute approach, the conceptual approach, and the historical approach. Primary legal materials include the 1961 Vienna Convention on Diplomatic Relations, the 1998 Rome Statute, particularly Article 27 concerning the Irrelevance of Official Capacity, the United Nations General Assembly Resolution ES-11/1 of 2022, and the International Criminal Court’s arrest warrant against Vladimir Putin issued in 2023. The findings demonstrate that the 1961 Vienna Convention contains a significant normative gap in addressing the abuse of diplomatic immunity within the context of international armed conflicts. The persona non grata mechanism has proven inadequate as an instrument of legal accountability, while Article 27 of the Rome Statute does not explicitly extend to active diplomats, thereby creating a normative gray area that may be exploited as a loophole for impunity. This study concludes that international legal reform should move toward a paradigm shift from absolute immunity to conditional functional immunity, namely a form of immunity that may be revoked through an independent international legal mechanism, regardless of the political discretion of the sending state.
