OTTAWA -- The Supreme Court of Canada has refused to hear an appeal by a retired Quebec judge who was sentenced to life in prison for the murder of his wife.

Jacques Delisle was found guilty in 2012 of the premeditated murder of his 71-year-old wife, Nicole Rainville.

The Quebec Court of Appeal upheld the verdict earlier this year despite Delisle maintaining the trial judge had given the 12 jurors erroneous directives.

The former appeals court justice testified at his trial that his wife, who was paralyzed, took her own life with a revolver that was found next to her.

He claimed to have found the woman dead with a gunshot to the head when he returned to his Quebec city home in November 2009.

The Crown argued that Delisle wanted to get rid of his wife to live with his mistress and avoid an expensive divorce.

Delisle was believed to be first Canadian judge to stand trial for such a crime.
