Possible Limitations to the Role of Subsequent Agreements and Subsequent Practice – Viewed from Some State Practices

Abstract The International Law Commission completed its work on subsequent agreements and subsequent practice in relation to the interpretation of treaties. While acknowledging the importance of the work, this article attempts to highlight some issues that may limit treaty interpretation through subsequent agreements and subsequent practice. Concrete examples of treaties on the avoidance of double taxation and a treaty ending a war are used to illustrate such potential limitations.
