What say the Governor General?

Nicholas A. MacDonald and James W.J. Bowdenargue that the Governor General should not refuse a request to prorogue Parliament.

This paper does not intend to ignore or gloss over the way that the prorogations of 1873 and 2008 unfolded in reality; clearly the majority of the political actors - certainly Lord Dufferin and Michaelle Jean themselves - believed that the Office of the Governor General possessed the reserve power to accept or reject the prime minister’s request. But based on the available evidence, we can only conclude that the governor general’s reserve power ought not to apply to prorogation.
