One of the three standards of review deployed by Canadian courts in reviewing administrative decision-making. This is an intermediate standard employed frequently in appeals from expert administrative tribunals and reflecting a certain level of judicial deference or respect for the decision or action under challenge. It is sometimes referred to as “unreasonableness simpliciter” to distinguish it from the even more deferential standard of “patent unreasonableness.”
