What is a non-self-executing treaty?

A non-self-executing treaty is a treaty that requires the passage of additional legislation or other actions by a state before it can have legal effect within that state’s legal system. In contrast to treaties that automatically become part of domestic law upon ratification (known as self-executing treaties), non-self-executing treaties need external implementation through specific legislative measures or administrative actions to be enforceable.

This characteristic is significant as it reflects the relationship between international and domestic law, indicating that simply ratifying a treaty does not mean it will have immediate legal implications without the proper domestic framework to enact it. In practice, this can lead to varying interpretations and applications of international agreements, as different countries may have different legislative processes, timelines, or legal cultures that influence how and when such treaties are implemented.

The other options do not accurately capture the definition of a non-self-executing treaty. A treaty that is effective immediately refers to self-executing treaties, while the idea that all member states automatically adopt a treaty misconstrues how treaties function in international law, which may involve ratification processes unique to each state. Lastly, the concept of a treaty that only functions during wartime doesn't relate to the classification of treaties based on their execution requirements and scope
