Quorum
The quorum of a committee of the whole is the same as for the Senate, that is, a quarter of the whole number of senators, 19 senators.[15]
If a senator draws attention to the lack of a quorum in committee of the whole, the bells are rung for four minutes as in the Senate, but if a quorum is then not present, the committee reports to the Senate, the President resumes the chair and there is then a further opportunity to form a quorum in the Senate. If a quorum is then present, proceedings in the committee resume.[16] If the absence of a quorum is revealed by a division in a committee, no decision is reached by the division, and the lack of a quorum is similarly reported to the Senate.[17] If proceedings in committee are interrupted by the absence of a quorum those proceedings are automatically made an order of the day for the next day of sitting and are called on accordingly.[18]
