members of the judiciary department are appointed by him, can be removed by him on the address of the two Houses of Parliament, and form, when he pleases to consult them, one of his constitutional councils. One branch of the legislative department forms also a great constitutional council to the executive chief, as, on another hand, it is the sole depositary of judicial power in cases of impeachment, and is invested with the supreme appellate jurisdiction in all other cases. The judges, again, are so far connected with the legislative department as often to attend and participate in its deliberations, though not admitted to a legislative vote.
From these facts, by which Montesquieu was guided, it may clearly be inferred that, in saying “There can be no liberty where the legislative and executive powers are united in the same person, or body of magistrates,” or, “if the power of judging be not separated from the legislative and executive powers,” he did not mean that these departments ought to have no partial agency in, or no control over, the acts of each other. His meaning, as his own words import, and still more conclusively as illustrated by the example in his eye, can amount to no more than this, that where the whole power of one department is exercised by the same hands which possess the whole power of another department, the fundamental principles of a free constitution are subverted. This would have been the case in the constitution examined by him, if the king, who is the sole executive magistrate, had possessed also the complete legislative power, or the supreme administration of justice; or if the entire legislative body had possessed the supreme judiciary, or the supreme executive authority. This, however, is not among the vices of that constitution. The magistrate in whom the whole executive power resides cannot of himself make a law, though he can put a negative on every law; nor administer justice in person, though he has the appointment of those who do administer it. The judges can exercise no executive prerogative, though they are shoots from the executive stock; nor any legislative function, though they may be advised with by the legislative councils.
