was specially averred that to compel the corporation to pay the taxes would' be to deprive it of its property without due ' process of law, in violation of the Fourteenth Amendment to the Constitution of the United States. The second plea substantially reiterated the averments of the first, and, in addition, specially alleged that all the persons who owned the-distilled spirits resided outside of the State of Maryland •and could not be taxed in personam, and that, by the construction given to the constitution of the State by the highest court of the State, .the property, although situated in the State, was not susceptible of being taxed, and, therefore, the taxes were void, and there was no power to cast upon the corporation the duty of paying them, and to compel the corporation to pay the taxes would be a violation of the due process clause of the Fourteenth Amendment.
A demurrer filed by the city to both pleas, on the ground that they stated no defense, was sustained without an opinion. The distilling company, electing to stand upon its pleas, judgment was entered against it for the’amount of the taxes. Thereupon a writ of error directly from this court was prosecuted upon the assumption that Questions under the Constitution of the United States were involved which gave a right to an immediate resort to this court for their, solution. Upon the correctness of such assumption our jurisdiction depends. The assumption, however, may not be indulged in simply because it appears from the record that a Federal question was- averred, if such question be obviously frivolous 6r plainly unsubstantial, either because it is manifestly devoid of merit or because.its unsoundness so clearly results from the previous decisions of this court as to foreclose the subject and •leave no room for the inference that the questions sought to be raised .can be the' subject of controversy.
