Binnie wrote that section 15 should not be twisted by claimants choosing comparator groups whose situations do not match their own. Thus, courts can reject a claimant's choice regarding a comparator group. While the Federal Court of Appeal accepted the claimant's choice for a comparator group on the grounds that the claimant had evidence to back it up, Binnie, citing "Granovsky" and "Law", replied the court can take a larger role in evaluating the correctness of the comparison. To select a comparator group, Binie wrote groups must be similar except with respect to one characteristic which is the basis of discrimination. The government objective is important to consider, though Binnie cautioned that if the government's selected recipients for a benefit was narrowed too exclusively, section 15 would not protect this benefit on the grounds that members of the recipient group are equal to one another.
