During a bitter strike at the Giant Mine, a striking miner evaded security, entered the mine, and planted a bomb that killed nine replacement miners.
The surviving family members and a first responder sued the mine's security firm, the territorial government, and the national union in negligence.
The Supreme Court of Canada held that while the security firm and the government owed a duty of care to the miners, they did not breach the standard of care.
The Court also held that the national union and local union were separate legal entities, and the national union was not directly or vicariously liable for the criminal acts of the striking members.
The appeals were dismissed.
