While, as has been said, the principle of the separation of powers has generally been accepted as binding in our systems of constitutional jurisprudence - state and national - the practical necessities of efficient government have prevented its complete application. It has from the beginning been necessary to vest in each of the three departments of government certain powers which, in their essential nature, would not belong to it. Thus, to mention only a few of the more evident examples, the courts have been given the essentially legislative power to establish rules of practice and procedure, and the executive power to appoint certain officials - sheriffs, criers, bailiffs, clerks, etc.; the executive has been granted the legislative veto power, and the judicial right of pardoning; the legislature has been given the judicial powers of impeachment, and of judging of the qualifications of its own members, and the Senate, the essentially executive power of participating in the appointment of civil officials.

8 The principle of the separation of powers does not limit Congress when providing governments for the Territories, for as to this Congress has complete discretion.

Not only this, but as we shall later see, the principle of the separation of powers does not prevent the legislative delegation to executive officers both of a considerable ordinance-making power, and of authority to pass, with or without an appeal to the courts, upon questions of fact. Essentially, the promulgation of administrative orders or ordinances is legislative in character, and the determination of facts after a hearing is judicial. In both cases, however, these functions are performed in pursuance of statutory authority, and as incidental to the execution of law. In like manner, the legislature is conceded to have, as incidental to its law-making power, the essentially judicial function of punishing for contempt or disobedience to its orders.
