McKay v. Kalyton — Opinion of the Court
“ It is contended that we are without jurisdiction because no title, right, or immunity was specially set up or claimed under any Federal statute and denied. But, leaving aside for a moment all other considerations, it is plain that the defendant below set up a claim of immunity from suit in the state court under the laws of the United States, and that the right to the immunity so asserted under an act or acts of Congress was expressly considered and denied by the state court. ”
