Thank you.
Chapter 12 in House of Commons Procedure and Practice, under “A Decision Once Made Must Stand”, reads as follows:
A decision once made cannot be questioned again but must stand as the judgment of the House. Thus, for example, if a bill or motion is rejected, it cannot be revived in the same session, although there is no bar to a motion similar in intent to one already negatived but with sufficient variance to constitute a new question. This is to prevent the time of the House being used in the discussion of motions of the same nature with the possibility of contradictory decisions being arrived at in the course of the same session.
