When nurses moved from casual positions into permanent employment, a dispute arose over whether their earlier service counted toward vacation entitlements under a collective agreement. Their union grieved the interpretation adopted by the employer. The labour arbitrator concluded that the applicable agreement didn't require prior casual service to be included in the way the union proposed.
The union challenged the award. A reviewing judge set it aside, finding that the arbitrator hadn't adequately explained the result. The Newfoundland and Labrador Court of Appeal restored the award, and the dispute reached the Supreme Court of Canada as Newfoundland and Labrador Nurses' Union v. Newfoundland and Labrador (Treasury Board), 2011 SCC 62.
The Supreme Court dismissed the union's appeal. It held that alleged insufficiency of reasons is considered as part of assessing whether an administrative decision is reasonable, rather than treated as an automatic, separate basis for setting the decision aside. Reasons have to be read in the context of the evidence, the submissions, the record and the result. The question isn't whether the decision maker answered every argument or wrote the analysis as a reviewing judge might have preferred.
That approach didn't make reasons optional. There still has to be enough explanation to understand why the decision was reached and to permit meaningful review. In this case, the arbitrator's interpretation of the collective agreement was reasonably supported when the decision and surrounding context were read together. The Court found no basis to overturn the result merely because a fuller explanation could have been written.
The case matters to employers and unions because collective agreements often generate disputes about seniority, benefits and the classification of earlier service. It also matters to those who prepare arbitration records and challenge awards. A complaint that reasons are incomplete isn't the same as showing that the interpretation or conclusion is unreasonable.
Later Supreme Court jurisprudence has further developed the framework for reviewing administrative reasons. Nurses' Union remains an important part of that history, but a current judicial review should be assessed under the governing modern framework rather than relying on this decision in isolation.
