The applicant was elected as a councillor of the Samson Cree Nation.
The Election Appeal Board invalidated his election because he performed work duties during the campaign, allegedly breaching a requirement to take leave without pay.
On judicial review, the Federal Court found the Board's decision unreasonable.
The Board found no corrupt practice but incorrectly characterized the breach as rendering the applicant ineligible.
The Court held the Board failed to consider whether the breach might have affected the election result, as required by the Nation's Election Law.
The decision was quashed and the applicant reinstated.
