1. Section 71(1)(a) of the Access to Information and Protection of Privacy Act permits suspension or cancellation of a media licence for misrepresentation or non-disclosure of material facts occurring after registration, not only those occurring during or prior to registration. 2. Before convicting a media service under section 71(1)(a), the Commission must comply with section 71(4) by giving notice of its intention to cancel, stating reasons, and allowing the media service a reasonable opportunity to show cause. Failure to do so renders the conviction irregular. 3. Judicial review is concerned with the decision-making process, not the correctness of the decision. A decision can only be set aside for gross unreasonableness if it is so outrageous as to be explicable only on the basis of mala fides, ulterior motive, or failure to apply the mind. 4. Where a tribunal has discretion to impose a particular penalty for proven contraventions, a review court cannot interfere with the exercise of that discretion even if it considers the penalty severe, as this is a matter for an appeal court.
