Q1. The Vienna Convention on the Law of Treaties (VCLT) provides that a treaty is void if, at the time of its conclusion, it conflicts with a peremptory norm of general international law (jus cogens). Which of the following best describes the legal status of a treaty in relation to the phrase "currently in force or awaiting ratification" within the context of the VCLT?
-
A. It refers to treaties that have been ratified by all parties and are actively being implemented.

Explanation: The phrase "currently in force or awaiting ratification" in the VCLT, in the context of peremptory norms, refers to the treaty's legal status at the time of its conclusion. A treaty that conflicts with a peremptory norm (jus cogens) at the time of its conclusion is void, regardless of whether it is in force or awaiting ratification. The phrase encompasses treaties that are already in force and those that are in the process of being ratified, as the relevant point is the treaty's compatibility with jus cogens at the moment it is concluded, not its stage of ratification.
