The applicant sought judicial review of a decision by the Union Bar First Nation to remove him from its band list.
The applicant had been treated as a member since birth and had received band benefits until 2019.
The Federal Court found that the band made a reviewable decision and that the decision breached procedural fairness as it was made without notice, disclosure, or an opportunity to be heard.
The decision was also deemed unreasonable because there was no factual or legal basis to revoke membership.
The Court quashed the decision, reinstated the applicant's membership without interruption, and awarded lump sum costs to the applicant.
