Act of state
Now a state, rather like a corporation, is a juridical being — a fiction of the law — with no res extensa as such. It exists on the rarefied non-material plane of jurisprudence. There are, thus, only a certain number of things that, without the agency of one if its employees, a state can do, and these involve enacting and repealing laws, promulgating and withdrawing regulations, signing treaties, entering contracts and, where is has waived its sovereign immunity, litigating their meaning.
