In the first decade of the present millennium, an apparently innocuous and then little used provision in the Vienna Convention on the Law of Treaties caught wide attention when it proved case dispositive in the decision of the International Court of Justice (ICJ) in Oil Platforms. Article 31(3)(c), which appears at the conclusion of the Convention's general rule of interpretation, requires that '[t]here shall be taken into account...any relevant rules of international law applicable in the relations between the parties.' In the hands of the International Law Commission (ILC) Study Group on fragmentation, reporting three years later in 2006, this provision was found to give effect to a more general principle: the principle of systemic integration. The idea was a beguilingly simple one.
This work investigates the legal significance and application of Article 31(3)(c) of the Vienna Convention on the Law of Treaties as a mechanism for systemic integration in international law. Campbell McLachlan KC examines how this specific provision, once considered obscure, functions as a bridge between disparate international legal regimes. By analyzing the International Law Commission's findings on fragmentation, the author argues that systemic integration serves as a vital interpretive tool for maintaining coherence within the international legal order.
