William Strong, Supervisors v. Durant — Opinion of the Court
“ Yet there is no substantial difference in principle between the allowance of such an injunction, and that of one against a proceeding in aid of an execution; a mandamus to levy an authorized tax to pay a judgment. The District Courts of Iowa are independent of each other. Will the injunction of one District Court limit the power of another District Court to enforce its judgment? To this no one would hazard an affirmative answer. Certainly the Circuit Court of the United States are as exempt from State control by State courts, as are the District Courts of the State from control by each other. ”
