‘No person,’ says the constitution, ‘shall be convicted of treason unless on the testimony of two witnesses to the same overt act, or on confession in open court.’
Here the language of the constitution is addressed especially to the courts. It prescribes, directly for them, a rule of evidence not to be departed from. If the legislature should change that rule, and declare one witness, or a confession out of court, sufficient for conviction, must the constitutional principle yield to the legislative act?
From these and many other selections which might be made, it is apparent, that the framers of the consti- [5 U.S. 137, 180] tution contemplated that instrument as a rule for the government of courts, as well as of the legislature.
Why otherwise does it direct the judges to take an oath to support it? This oath certainly applies, in an especial manner, to their conduct in their official character. How immoral to impose it on them, if they were to be used as the instruments, and the knowing instruments, for violating what they swear to support!
The oath of office, too, imposed by the legislature, is completely demonstrative of the legislative opinion on this subject. It is in these words: ‘I do solemnly swear that I will administer justice without respect to persons, and do equal right to the poor and to the rich; and that I will faithfully and impartially discharge all the duties incumbent on me as according to the best of my abilities and understanding, agreeably to the constitution and laws of the United States.’
Why does a judge swear to discharge his duties agreeably to the constitution of the United States, if that constitution forms no rule for his government? if it is closed upon him and cannot be inspected by him. (more…)
