A serious question, however, has been made, whether the interests of the public service, involved in the relations of the two departments, would not have been placed upon a better footing, if some of the higher officers of state had been admitted to hold seats in the legislature. Under the English constitution, there is no practical difficulty, at least in modern times, in determining the general principle that is to distinguish between the class of officers who can, and those who cannot, be usefully allowed to have seats in the House of Commons. The principle which, after much inconsistent legislation and many abortive attempts to legislate, has generally been acted on since the reign of George II., is, that it is both necessary and useful to have in that House some of the higher functionaries of the administration; but that it is not at all necessary, and not useful, to allow the privilege of sitting in Parliament to subordinate officers.[178] The necessity of the case arises altogether from the peculiar relations of the ministry to the crown, and of the latter to the Commons. If the executive government were not admitted, through any of its members, to explain and vindicate its measures, to advocate new grants of authority, or to defend the prerogatives of the crown, the popular branch of the legislature would either become the predominant power in the state, or sink into insignificance. This is conceded by the severest writers on the English government. But when we pass from a civil polity which it has taken centuries to produce, and which has had its departments adjusted much less by reference to exact principles than by the results of their successive struggles for supremacy over each other, and when we come to an original distribution of powers, in the arrangements of a constitution made entire and at once by a single act of the national will, we must not give too much effect to analogies which after all are far from being complete. In preparing the Constitution of the United States, its framers had no prerogative, in any way resembling that of the crown of England, to consider and provide for. The separate powers to be conferred on the chief magistracy--aside from its concurrence in legislation--were simply executive and administrative; the office was to be elective, and not hereditary; and its functions, like those of the legislature, were to be prescribed with all the exactness of which a written instrument is capable. There was, therefore, little of such danger that the one department would silently or openly encroach on the rights or usurp the powers of the other, as there is where there exists hereditary right on the one side and customary right on the other, and where the boundaries between the two departments are to be traced by the aid of ancient traditions, or collected from numerous and perhaps conflicting precedents. There was no such necessity, therefore, as there is in England, for placing members of the
