Huband ran in the upscale riding of River Heights in the 1973 provincial election, and lost to Progressive Conservative leader Sidney Spivak.
Huband was elected leader of the Manitoba Liberal Party on February 22, 1975, defeating his lone opponent Lloyd Henderson by 381 votes to 87.
Huband declared himself a candidate when the central Winnipeg seat of Crescentwood became vacant in early 1975, after the one-vote victory of NDP MLA Harvey Patterson in the 1973 election was overturned.
In 2007, Huband retired from the Manitoba Court of Appeal and resumed private practice, joining the firm of Taylor McCaffrey LLP.
Huband tried to return to politics when he won the Liberal nomination in the riding of Portage la Prairie during the 2019 provincial election, and finished a distant third.
