A more thorough explanation: The legal English definition of the term “validity of treaty” refers to the legal status of a treaty in international law. A treaty is considered valid if it has been concluded in accordance with the rules and procedures set out in international law, such as the Vienna Convention on the Law of Treaties. A valid treaty is binding on the parties to it and must be respected and upheld by them. The validity of a treaty may be challenged on various grounds, such as a party’s lack of capacity to enter into the treaty, a violation of a peremptory norm of international law, or a material breach of the treaty’s provisions.
Example: The validity of the treaty was called into question due to a lack of proper ratification by all parties involved.
