Sobeys is appealing a human rights decision against the grocery store chain in Nova Scotia.
Last week, a board of inquiry with the Nova Scotia Human Rights Commission found that staff at a Halifax-area Sobeys racially discriminated against a customer after falsely accusing her of shoplifting.
In documents filed with the Nova Scotia Court of Appeal, Sobeys says inquiry chair Marion Hill allowed a breach of the rules of procedural fairness.
The document also says Hill made arbitrary rulings against the company on evidentiary issues, and didn't give Sobeys a fair opportunity to examine and cross-examine witnesses.
In May 2009, Andrella David was accused by an employee at the Sobeys in Tantallon of being a known shoplifter.
The board's decision says there was no indication that David, a black woman, had attempted to steal from the store.
Hill wrote that racial profiling was a factor in the decision to confront David, who was discriminated against based on her skin colour and her perceived source of income.
Hill said the identification of David as a known shoplifter was not justified.
