Yes, of course.
So you and I are running in an election, and you have the support of nobody, but a few more seats than I do. I have the support of other parties. You approach the GG and say, “I got this”, even though there were public declarations that, at the first moment you try it, others will bring you down. The GG would then turn to the second-place party, under our current mechanisms and rules, and say, “I don't have confidence in Larry's ability to hold government, and my job as Governor General is to seek stability”, which is one of the purviews of the Governor General, “and I'm turning to Cullen to see if he can do it.” That exists under our rules currently, does it not?
