On a point of order, Mr. Chair, having chaired House of Commons committees before, my recollection of a dilatory motion is to adjourn the committee, not to adjourn debate.
I never recall a situation where a member of a committee was permitted to move a motion to adjourn debate on a motion. That would be considered a dilatory motion.
My understanding that adjourning a committee is non-debatable, it being a dilatory motion, but not to adjourn debate on a motion in front of the committee.
