On the night of November 4, 1981, (widely known among Quebec sovereigntists as "La nuit des longs couteaux" and in the rest of Canada as the "Kitchen Accord") Federal Justice Minister Jean Chrétien met with all of the provincial premiers except René Lévesque to sign the document that would eventually become the new Canadian constitution. The next morning, they presented the "fait accompli" to Lévesque. Lévesque refused to sign the document and returned to Quebec. In 1982, Trudeau had the new constitution approved by the British Parliament, with Quebec's signature still missing (a situation that persists to this day). The Supreme Court of Canada confirmed Trudeau's assertion that every province's approval is not required to amend the constitution. Quebec is the only province not to have formally assented to the patriation of the Canadian constitution in 1982.
