Mahlon Pitney, Houston v. Ormes — Opinion of the Court
“ The principal contention is that, because the object of the suit and the effect of the decree were to control the action of the appellants in the performance of their official duties, the suit was in effect one against the United States. But since the fund in question has been appropriated by act of Congress for payment to a specified person in satisfaction of a finding of the Court of Claims, it is clear that the officials of the Treasury are charged with the ministerial duty to make payment on demand to the person designated. ”
