Reservations, Interpretation, and Validity in Treaty Law
Reservations, interpretation, and validity are among the most important dimensions of treaty law because they determine how treaty obligations are qualified, understood, and assessed as legally effective within international legal order. This article examines the Vienna Convention framework governing reservations, the object and purpose test, acceptance and objection, interpretative declarations, and the general rules of treaty interpretation under Articles 31 to 33. It also analyzes the grounds of treaty invalidity, including coercion, error, fraud, and conflict with peremptory norms of general international law. By bringing these doctrines together, the article shows how treaty law balances sovereign consent, legal coherence, interpretive discipline, and the structural limits of valid international agreement.
