The problem with even having it well-documented which entities fall under which jurisdiction is that you can just change your mind and fight and lose in the courts later when it serves the purpose of delaying the inevitable outcome. It is often the case that the nation-to-nation relationship is very complex. But even where it is simple the existence of the relationship as a barrier can be exploited to the detriment of the citizenry. (IMO in Canada the courts have been getting fed up with these maneuvers and are levying large penalties in the hopes of deterring the strategy.)
