|Same by practice. The senate can reject, but not amend, taxation or appropriation bills. Not in Canadian constitution. The senate may return money and appropriation bills to the house of representatives, requesting the omission or amendment of any provision therein, but it is optional for the house to make such omissions or amendments. No such provision. If bills, other than money bills, have twice been passed by the house of representatives and twice been rejected by the senate or passed by that body with amendments to which the house of representatives will not agree, the governor-general may dissolve the two houses simultaneously; and if, after the new election they continue to disagree, the governor-general may convene a joint sitting of the members of the two houses, who shall deliberate and vote upon the bill, which can only become law if passed by an absolute majority of the members sitting and voting. _Legislative Powers of the _Legislative Powers of the Parliament of the Dominion_.
