William Strong, Supervisors v. United States (85 U.S. 71…
“ It is very plain that a mandamus will not be awarded to compel county officers of a State to do any act which they are not authorized to do by the laws of the State from which they derive their powers. Such officers are the creatures of the statute law, brought into existence for public purposes, and having no authority beyond that conferred upon them by the author of their being. ”
