 Under this standard of review, a court would only substitute its own reasoning for the lower decision-maker's if it was so egregious as to be patently unreasonable.This standard was found to be dissatisfactory as it allowed certain decisions which were unreasonable but not patently unreasonable to be upheld, giving rise to situations where certain people were told to accept an irrational decision of an administrative body.The Supreme Court abolished the patent unreasonableness standard in favour of retaining the two standards of correctness and reasonableness.
