I have only alluded to the Law of Corporations; but this law is of weight in determining the present case. According to this law, the rule of the majority must prevail. Indeed, an eminent jurist says that this rule is according to the Law of Nature, as it is unquestionably according to the Roman Law, and the modern law of civilized states.[5] But what is a legislative body but a political corporation? Therefore, when asked if a Legislature, even by legislative act, may set aside the rule of the majority in the election of Senators, I must candidly express a doubt. The Constitution confides this power to the “Legislature”; but the “Legislature” consists of a majority. _Ubi major pars est, ibi totum_: “Where the greater part is, there is the whole.” Such is an approved maxim of the law; and this maxim has in its support, first, the Law of Nature, secondly, the Law of Corporations, thirdly, the Parliamentary Law, and, fourthly, the principles of republican government. Who ever thought of saying, Where the minority is, there is the whole? But we are not asked now to decide the question, whether the Legislature, by legislative act, may substitute the rule of a minority for the majority. That question is not necessarily before us. In the present case there has been no legislative act; and the question is, whether the rule of the minority may be substituted for the majority by the abnormal body known as joint meeting. On this point the conclusion is clear. Even assuming that this substitution may be made by legislative act, it does not follow that it may be made in joint meeting. Surely, such a change is of immense gravity, and should be made only under all possible solemnities and safeguards. If ever there was occasion for the delays and precautions provided by legislative proceedings, with three different readings in each separate House, it must be when such a change is in question. Such surely is the suggestion of reason. But the Constitution itself, which delegates to the “Legislature” of each State the power to _prescribe the manner_ of electing Senators, uses language not open to evasion. This power is to be exercised by the “Legislature,” which may prescribe the manner. It is not to be exercised by any other body than the Legislature; and the manner is to be prescribed by the Legislature. But, assuming that it may be exercised in joint meeting, it is clear that this must be in pursuance of some legislative act, prescribing in advance the manner.
