PROFESSIONS AND TRADES — health care professional — pharmacy — appeal from decision of the Pharmacy Council to impose conditions on pharmacist’s registration under s 159B of the National Law — whether grounds were with respect to a point of law — whether a “point of law” is limited to a pure point of law, or whether it includes a mixed point of fact and law — whether the decision to impose conditions was beyond power to the extent that the conditions restrict other practitioners’ practice at the appellant’s pharmacy — whether that decision was beyond power to the extent that the conditions relate to a pharmacy business — whether the respondent’s reasoning in imposing a condition was illogical or irrational — whether a condition requiring the appellant to consent to an audit was beyond power because it was not referable to an identified risk to the public, but was rather a condition to enable the respondent to investigate further matters
