It is the prerogative of the monarch to summon and prorogue Parliament. Parliament immediately impeached Danby, forcing Charles II to prorogue the session in December, 1678. Unable to elect a Speaker, Manning advised the President to prorogue Parliament. Harper again advised the Governor General to prorogue parliament on December 30, 2009. First, the president, on Cabinet's advice, may prorogue Parliament by proclamation in the "Government Gazette". The Governor may at any time, by Proclamation, prorogue or dissolve the Assembly. Among their powers included the right to summon, prorogue and dissolve the elected assembly. The Governor may also from time to time prorogue the Assembly or dissolve the Assembly. Where the Governor summons Assembly he is authorized to prorogue it too.
