144U.S.1, 5 (1892). "The Constitution empowers each house to determine its rules of proceedings. It may not by its rules ignore constitutional restraints or violate fundamental rights, and there should be a reasonable relation between the mode or method of proceeding established by the rule and the result which is sought to be attained. [...] The power to make rules is not one which once exercised is exhausted. It is a continuous power, always subject to be exercised by the house, and within the limitations suggested, absolute and beyond the challenge of any other body or tribunal."
144U.S.1, 6 (1892). "The general rule of all parliamentary bodies is that, when a quorum is present, the act of a majority of the quorum is the act of the body [...], except so far as [...] the terms of the organic act under which the body is assembled have prescribed specific limitations. [...] No such limitation is found in the Federal Constitution, and therefore the general law of such bodies obtains."
