ST-JEROME, Que. — Former doctor Guy Turcotte, who faces a retrial for killing his two children, wants Canada's highest court to stop the second process.
His lawyer, Pierre Poupart, informed a judge north of Montreal on Friday that the defence will ask the Supreme Court of Canada to weigh in on the matter.
The former cardiologist was not present in the courtroom in St-Jerome, Que.
It was the same courthouse where Turcotte admitted during his first trial that he stabbed his son Olivier, 5, and daughter Anne-Sophie, 3, in 2009.
But a jury accepted his defence that he was suicidal and despondent prior to the killings because his marriage was crumbling.
The not-criminally-responsible verdict in 2011 provoked outrage across Canada, with some calling for the death penalty.
He now faces another first-degree murder trial after the Quebec Court of Appeal ruled that the trial judge erred in his instructions to the jury.
Turcotte, 41, was released from a Montreal mental hospital in December 2012.
He was re-arrested in November.
