Note 146 — Chapter IX

Let the reader consult Mr. Hallam's acute and learned discussion of this exclusive privilege of the House of Commons, (Const. Hist., III. 37-46,) and he will probably be satisfied, that, whatever theoretical reasons different writers may have assigned for it, its origin is so obscure, and its precise limits and purposes, deduced from the precedents, are so uncertain, that it can now be said to rest on no positive principles. Its basis is custom; which, having no definite beginning, is now necessarily immemorial. It would not be quite safe, therefore, to reason upon the well-defined provision of our Constitution, as if there were a close analogy between the situation of the two houses of Congress and the two branches of the British legislature. The English example certainly had an influence, in suggesting the plan of such a restriction; but care must be taken not to overlook the peculiar arrangements which made it so highly expedient, that it may be said to have been a necessity, even if there had been no British example.
