In Carey v. Houston & Texas Central R.R. Co., 150 U.S. 170 (1893), in which a bill in equity had been filed in order to impeach and set aside a decree of foreclosure on the ground of fraud and want of jurisdiction in the foreclosure suit, it was held that no case for appeal directly to this court was made as one that involved the construction or application of the Constitution of the United States. In that case Mr. Chief Justice Fuller, delivering the opinion of the court, said: "It is argued that the record shows that complainants had been deprived of their property without due process of law, by means of the decree attacked, but because the bill alleged irregularities, errors and jurisdictional defects in the foreclosure proceedings and fraud in respect thereof and in the subsequent transactions, which might have enabled the railroad company upon a direct appeal to have avoided the decree of sale, or which, if sustained on this bill, might have justified the Circuit Court in setting aside that decree, it does not follow that the construction or application of the Constitution of the United States was involved in the case in the sense of the statute. In passing upon the validity of that decree the Circuit Court decided no question of the construction or application of the Constitution, and, as we have said, no such question was raised for its consideration. Our conclusion is that the motion to dismiss the appeal must be sustained."
