This article examines the complex process of interpreting treaties in the context of international law, focusing specifically on the guidelines, procedures, and legal perspectives provided by the “Vienna Convention on the Law of Treaties (VCLT).” Examining the fundamental ideas of good faith, the article clarifies how important they are in directing the process of interpretation. It explores how techniques like textual, contextual, historical, and teleological interpretation are applied and analyses how they interact to resolve interpretive uncertainties. The article also looks into the value of additional methods, such as follow-up agreements, in revealing the genuine objectives and intentions of treaty parties. By the process of a comparative examination of judicial strategies utilised by eminent international courts and tribunals, the article evaluates the practical application of these concepts and techniques in various legal settings. This thorough analysis adds to the continuing conversation about the development and application of international legal norms by clarifying the practical difficulties state and global organisations confront when navigating the complexities of treaty interpretation. It also improves our understanding of the complexities surrounding treaty interpretation.
