As an AI language model, I don't have the context to determine what specific document or agreement you are referring to. However, here is some information about Article 121 from different documents:
United States Constitution: Article 121 does not exist in the United States Constitution. The Constitution has seven articles, which define the framework of the federal government and its powers.
United Nations Convention on the Law of the Sea (UNCLOS): Article 121 of UNCLOS establishes rules related to the rights of coastal states over their territorial seas, contiguous zones, exclusive economic zones, and continental shelves.
Indian Constitution: Article 121 of the Indian Constitution prohibits discussions in Parliament or the state legislatures with respect to the conduct of any judge of the Supreme Court or of a High Court in the discharge of his duties.
If you could provide more context or information about which document or agreement you are referring to, I may be able to provide a more specific answer.
