On February 5, the Supreme Court of Canada (SCC) voted unanimously to strike down the blanket prohibition on physician-assisted suicide (PAS) and euthanasia that was in place since 1992. The ruling of Carter v. Canada is historic in that it would permit assisted suicide for psychological illness as well as physical.

Because the SCC has not defined or limited what can be considered “psychological suffering,” many are concerned that the subjective language of the ruling makes it vulnerable to abuses. The closest “definition” for either psychological or physical conditions is that it be “grievous and irremediable (including an illness, disease or disability) that causes enduring suffering that is intolerable to the individual in the circumstances of his or her condition.”

In a decision today with serious international ramifications, Canada’s highest court has overturned an absolute ban on assisted suicide/euthanasia and has given Parliament one year to create a “stringently limited, carefully monitored system of exceptions.”

The decision was unanimous, 9-0, and it should be viewed as a victory for advocates of assisted suicide and euthanasia. The ruling chisels away at a prior understanding in Canadian law of human life—even difficult or painful life—as sacred.

In the policy interplay between the United States and Canada, Americans can expect that “right-to-die” activists will be very motivated to use this Canadian case as an example, just as Canadian activists pointed to the “success” of “aid-in-dying” laws in Washington and Oregon.
