text: Reforms Following public protest, the order-in-council that authorized the forced deportation was challenged on the basis that the forced deportation of Japanese Canadians was a crime against humanity and that a citizen could not be deported from his or her own country. The federal cabinet referred the constitutionality of the order-in-council to the Supreme Court of Canada for its opinion. In a five to two decision, the Court held that the law was valid. Three of the five found that the order was entirely valid. The other two found that the provision including both women and children as threats to national security was invalid. The matter was then appealed to the Judicial Committee of the Privy Council in Britain, at that time the court of last resort for Canada. The Judicial Committee upheld the decision of the Supreme Court. In 1947, due to various protests among politicians and academics, the federal cabinet revoked the legislation to repatriate the remaining Japanese Canadians to Japan. It was only in April 1949 that all restrictions were lifted from Japanese Canadians.
  Issues surrounding the internment of Japanese Canadians also led to changes to Canadian immigration policy, with the legislation gaining momentum after a statement made by the Prime Minister on May 1, 1947:
  This reform to immigration policy was deemed necessary on two grounds: the inevitable post-war crisis of displaced persons from Europe, and the growing number of Canadians who wished to bring family to Canada following the war—the large number of war brides being the chief concern on this front. Mackenzie King believed that Canada was under no legal obligations to make such accommodations, only a moral obligation. During this time, the Canadian government also made provisions to begin the repeal of the discriminatory Chinese Immigration Act of 1923.
