I've consulted with the clerk extensively on this point. This was not the first time I've heard of this. There would be a process, but it's quite sophisticated.
There would have to be a motion that would have to be voted on in regard to negativing the previous vote. It would be possible, but let's put it this way: We'd prefer not to set a precedent in that regard. It's a slippery slope once you negative one vote; it then calls into question the consistency of our voting regimen.
That's where I would rule, Madame Gaudreau.
