INVIOLABILITY OF DIPLOMATIC PREMISES: A FUNCTIONAL NECESSITY AND REPRESENTATIVE THEORY ANALYSIS

Abstract

Diplomatic premises provide a crucial administrative and residential forum for the performance of diplomatic functions. On the one hand is the need to guarantee the protection of diplomatic premises. On the other hand is the need to prevent the abuse of diplomatic premises. The former is secured through the principle of inviolability, including the prohibition of entry by the receiving State except with the consent of the sending State. However, little provision is made to prevent or deter the abuse of diplomatic premises. This paper examines the justifications for the inviolability of diplomatic premises through the functional necessity and representative theories. It adopts the doctrinal research methodology. The Vienna Convention on Diplomatic Relations constituted the primary source of data, while secondary sources included books, journal articles, and online materials. The paper finds that the fundamental basis of diplomatic immunity is twofold: representative and functional necessity. Under the representative theory, diplomatic immunities and privileges derive from the sovereign status of States in international law, which precludes one State from being subject to the jurisdiction of another. The functional necessity theory, on the other hand, is anchored on the argument that such immunities and privileges are essential for the effective performance of diplomatic functions. The paper argues that there is no sufficient justification under the functional necessity theory for denying the receiving State a limited or qualified right to enter and search diplomatic premises where there are reasonable grounds to suspect that the premises are being used for criminal activities. It concludes that diplomatic relations should be anchored on transparency and openness rather than treated as secret missions within the receiving State. Accordingly, the absolute inviolability of diplomatic premises under the Vienna Convention on Diplomatic Relations (VCDR) should be reconsidered to better protect the national security interests of the receiving State while promoting greater openness in international relations.
