Divine right of kings.  Stephen Harper.  I'm not getting the distinction, Wilf ;-)

But seriously, the Speaker's role is to protect the privileges of Parliamentarians, as just about every candidate for the job said in their speeches the other week.  I suspect he would be summoned to play some role in that circumstance.

One picky point to another commenter though ... technically the government did pass one vote of confidence, because the Throne Speech did pass on a voice vote on division right after the Economic and Fiscal Update.  One point in the government's favour.  But really ... a sitting of less than a month?  With no Supply Motion adopted?  I don't think that fits the bill for prorogation.
