At the same time, the government was approaching a final resolution on the constitutional issues of the past decades. In 1981, Paul Martin, Sr., John Roberts, and Mark MacGuigan were sent to the UK to discuss the patriation project; Martin noted that during this time the Queen had taken a great interest in the constitutional debate, and the three found the monarch "better informed on both the substance and politics of Canada's constitutional case than any of the British politicians or bureaucrats." Elizabeth continued to assist with the project until a conclusion was reached the following year, when in Ottawa on 17 April she proclaimed the Constitution Act, 1982, which, amongst other changes and additions, patriated the constitution, making it fully Canadian law, and entrenched the monarchy in Canada; any change to the position of the monarch or the viceroys thenceforth required the consent of the federal and all ten provincial legislatures. Trudeau commented in his memoirs: "I always said it was thanks to three women that we were eventually able to reform our Constitution[, including] The Queen, who was favourable... I was always impressed not only by the grace she displayed in public at all times, but by the wisdom she showed in private conversation."
