Colonial origins Under British colonial law prior to
Confederation, the Crown in Britain held the power to annul a statute passed by a colonial legislature, commonly called "
disallowance". The Crown would exercise this power on the advice of the
British government, if the colonial law was considered contrary to the policies of the British government, or if the statute exceeded the powers granted to the colonial legislature.
Situation at Confederation When Canada was created in 1867, this imperial power was carried forward by section 56, which required the
Governor General of Canada to forward copies of all statutes passed by the federal Parliament to one of the British cabinet ministers, typically the
Colonial Secretary. The British government then had up to two years to review the statutes, and to advise the monarch whether to disallow any of the statutes. This authority was to ensure the Canadian Parliament stayed within its constitutional authority, and did not pass any statutes that were contrary to British imperial policy. A statute that was disallowed nonetheless was considered to have been in force during the period from
royal assent by the Governor General, until the Governor General gave formal notice of disallowance to the
House of Commons and the
Senate. The British government disallowed the act because the
law officers of the Crown concluded that the
Oaths Act was unconstitutional. In their view, the act exceeded the power of the Parliament of Canada to regulate parliamentary proceedings under
section 18 of the Act, as that section read at that time. The
Oaths Act arose from the
Pacific Scandal that brought down the Conservative government of Prime Minister Macdonald in 1873. The scandal involved allegations that a business group vying for the contract to build the transcontinental railway to the Pacific coast had bribed members of the Conservative government in the
1872 election campaign. When the scandal broke, the
opposition in the
House of Commons called for a parliamentary inquiry, with the power to compel testimony under oath. Macdonald agreed to the passage of the
Oaths Act, but indicated that he had doubts about its constitutionality. Governor General
Lord Dufferin forwarded the act and various legal opinions to the British government for advice. On May 29, 1873, the colonial secretary, the Earl of Kimberley, sent a telegram to Dufferin, advising that the Law Officers had concluded that the act was
ultra vires, i.e. beyond the constitutional authority of the federal Parliament. The next month, Kimberley sent a second telegram, advising that the act had been disallowed. == Difference from reservation of bills ==
