Seriously?
ROYAL ASSENT TO A BILL
The Constitution Act, 1867, states that the approval of the Crown, signified by Royal Assent, is required for any bill to become law after passage by both the Senate and the House of Commons. A version of the bill that is identical to the one passed by the two Houses is approved by a representative of the Crown and is given “the complement and perfection of a law”.
There are two ways in which Royal Assent may be granted—through a written procedure and through the traditional ceremony, in which Members of the House of Commons join their Senate colleagues in the Senate Chamber.
The Royal Assent Act preserves the traditional ceremony by requiring that it be used twice in each calendar year, including for the first appropriation bill in each session.
