Supreme Court of Canada on Adequate Labour Tribunal Reasons

April 1, 2013 | Gerald D. Chipeur

On November 29, 2012, the Supreme Court of Canada accepted the arguments of Miller Thomson partner Kent Davidson and reinstated a decision of the Alberta Labour Relations Board. In so doing, the Supreme Court underscored the deference that appellate courts are prepared to afford administrative bodies.

The case was Construction Labour Relations – An Alberta Association v. Driver Iron Inc., 2012 SCC 65. It involved an appeal from an Alberta Relations Board decision interpreting section 176 and 178 of the Alberta Labour Relations Code.

The Alberta Labour Board’s decision was upheld on an initial judicial review by the Court of Queen’s Bench of Alberta. An appeal to the Court of Appeal of Alberta was allowed and the Board’s decision was quashed. Leave to appeal was secured by Construction Labour Relations, An Alberta Labour Association and an appeal to Canada’s highest court proceeded.

Both the argument and the Supreme Court of Canada’s decision were direct and to the point. They emphasized four now well settled principles of law:

  1. labour tribunal decisions are due deference by the courts, including the Supreme Court of Canada;
  2. an administrative tribunal does not need to consider and comment upon every issue raised by the parties in the tribunal’s reasons for decision;
  3. when interpreting a labour statute, a labour tribunal need not explicitly address in writing all possible shades of meaning of the statute;
  4. the fundamental issue for consideration by a reviewing court is whether the tribunal’s decision, viewed as a whole in the context of the record, is within the realm of reasonable outcomes.

The reasons for decision allowing the appeal were brief and unequivocal. The Supreme Court took just four paragraphs on one page to make the point that appeal courts must show restraint and give deference to administrative tribunals. The message is clear: courts are only to intervene where satisfied that the decision of an administrative decision maker is beyond reason. That alternative reasonable conclusions might also be drawn will not justify interference by a reviewing court.
