Portrait of David Josiah Brewer David Josiah Brewer Minnesota v. Hitchcock — Opinion of the Court

But the silence of counsel does not waive the question, nor would the express consent of the parties give to this court a jurisdiction which was not warranted by the Constitution and laws. It is the duty of every court of its own motion to inquire into the matter, irrespective of the wishes of the parties, and be careful that it exercises no powers save those conferred by law. Consent may waive an objection so far as respects the person, but it cannot invest a court with a jurisdiction which it does not by law possess over the subject-matter.
