For information, if I could first refer to page 1,051 of House of Commons Procedure and Practice, second edition, this is a section that has to do with the decision-making process in committee:
The Standing Orders do not require that notice be given before moving a motion in committee. However, to avoid situations where the members of a committee are forced to consider issues without warning, committees usually deem it appropriate to adopt rules on notice for substantive motions. Such notices normally require 24 or 48 hours.
This committee did adopt such a motion on March 11 with its other routine motions, and that motion reads as follows:
That 48 hours' notice be required for any substantive motion to be considered by the Committee, unless the substantive motion relates directly to business then under consideration, and that the notice of motion be filed with the Clerk of the Committee and distributed to members in both official languages before consideration is given.
What the chair has said is that this rule applies in the following way to the motion of Monsieur D'Amours, which is that since the committee is currently in a discussion of committee business and the member has an item of business to bring before the committee, the notice is not required in the present circumstances.
