by various treaties, conventions and organizations. Some treaties that use it include provisions that in addition to these States any other State invited by a specified authority or organization (commonly the United Nations General Assembly or an institution created by the treaty in question) can also participate, thus making the scope of potential signatories even broader. Interpretation of treaties Articles 31-33 of the VCLT entail principles for interpreting conventions, treaties etc. These principles are recognized as representing customary international law, for example by the International Law Commission (ILC). The interpretational principles codified in Article 31 are to be used before applying those of Article 32, which explicitly states that it offers supplementary means of interpretation. The European Court of Justice has also applied the interpretational provisions of the VCLT in different cases, including the Bosphorus Queen Case (2018), in which the court interpreted the extent of the term "any resources" in Article 220(6) of UNCLOS. The VCLT is often relied upon in investment arbitration cases.
