Wiener Übereinkommen über das Recht der Verträge
Similarly, Article 80 of the Vienna Convention on the Law of Treaties (which entered into force in 1980) requires a party to the convention to register any treaty to which it is a party once the treaty enters into force. However, neither Article 102 of the UN Charter nor Article 80 of the Vienna Convention on the Law of Treaties has preserved the latter part of Article 18 of the Covenant of the League of Nations. Consequently, failure to register a treaty "as soon as possible" is a violation of the Charter and Convention, but does not render the treaty invalid or ineffective.
