The answer is simple: Each motion must pertain to one of the committee's current studies or propose a new one, which is not the case here. It is really about getting information on everything that is being done on ArriveCAN. Even if we don't ask specific questions about the ongoing investigation—and in any case the RCMP wouldn't be able to answer them—the motion still has to be related to the ArriveCAN study, because that's what our questions are about.
As you know, we have to make sure that the motions we put forward relate to committee business. Had I not done so, you would have been the first to tell me that it was not germane to the committee's work. So the motion has to be based on a report by the Auditor General.
