The Supreme Court of Canada will revisit the issue of assisted suicide.
The court has agreed to hear an appeal in the case of Kay Carter and Gloria Taylor, who succeeded in briefly overturning the assisted suicide law in 2012.
A B.C. judge ruled the law unconstitutional, but delayed her ruling for a year to allow the federal government to rewrite the statute.
The provincial court of appeal overturned that decision.
The high court's decision comes more than 20 years after its landmark ruling on the issue in the case of Sue Rodriguez, which went against assisted suicide.
Both the principals in the present case have died, but the British Columbia Civil Liberties Association is continuing the fight.
The judge in the original case granted Taylor a constitutional exemption to permit her to seek physician-assisted suicide.
The appeal court allowed the exemption to stand, but Taylor eventually died of an infection in October 2012.
