The most well known application of the Nickle Resolution occurred when Prime Minister Jean Chrétien used it to prevent Canadian publishing mogul Conrad Black from becoming a British life peer. Black took the Prime Minister to court, which upheld the government's interpretation of the Resolution. Black eventually gave up his Canadian citizenship and was created Lord Black of Crossharbour in 2001
The Nickle Resolution was not a law or act of Parliament; it was a motion (brought forward by Conservative MP William Nickle) that an address be made to the King, requesting that he not grant "any title of honour or titular distinction ... save such appellations as are of a professional or vocational character or which appertain to an office," and that all hereditary titles held by Canadians become extinct upon the death of the incumbent. Although the resolution was passed by the Commons, the address to the King was never actually sent. Nevertheless, grants to Canadians ceased until they were revived by Richard Bedford Bennett during his term as prime minister, 1930 to 1935. When William Lyon Mackenzie King returned to power in 1935, he reinstated the former policy, which has been in effect ever since.
The resolution makes Canada the only Commonwealth Realm that does not allow for British titles. Other countries such as Australia, Jamaica, and Papua New Guinea still allow it. There is currently a debate in New Zealand over following Canada's example and banning the titles.
