 Lastly, in the search for a rule of recognition, some have pointed out that features like the inability of states freely to leave the UN, to take one example, have given a constitutional character to international law.

Features such as the non-denunciability of the UN Charter do however tell us something important about the nature of international law: they may evidence a distinctive constitutive force from which international law derives full legal character.
