When a committee is dealing with an amendment to a motion and it adjourns debate on the amendment, what it essentially means is that you cannot take up the main motion again. The reason is that the amendment supersedes it. You must deal with the amendment first. Now you can deal with the amendment either by adopting it, defeating it or adjourning the debate on it.
In this case, Mr. MacKinnon has moved that we adjourn the debate on the amendment. What that essentially means is that we cannot continue with the discussion in general of either your motion or the amendment, until such time as the committee wishes to bring it up at a future time, provided the motion is agreed to.
