Latimer v. The Queen
Supreme Court of Canada
1 S.C.R. 3 (2001)
Robert Latimer (defendant) was the father of Tracy, a twelve-year-old with cerebral palsy who was completely dependent on others, endured substantial pain that could not be treated with pain killers due to interference with her anti-epileptic medication, and whose parents had declined both a feeding-tube pain-medication option and placement in a group home. When Tracy was scheduled for another surgery doctors expected would be very painful, Latimer placed her in his car and had her inhale carbon monoxide until she died, and he was convicted of second-degree murder.
Whether the defense of necessity is available to justify an act of euthanasia where the deceased suffers from a non-life-threatening condition.
