[16] With respect to the grounds found in s 20(2) (d) and (e) of the Act, the applicant has not established that the respondent's decision involved any improper exercise of power or error of law. The applicant has not articulated that the respondent failed to take a relevant consideration into account, acted in bad faith, failed to have regard to the merits of his complaints, did not act in accordance with a rule and/or policy or reached a decision that is unreasonable in the Wednesbury[5] sense. As the respondent submitted, there was adequate material before the Commissioner where he could form the view based on his own Commission investigation report and the QLS reports that the respective advices sought from counsel were appropriate in the circumstances and involved no potential misconduct, and thus reach the decision he did. Indeed as noted, the Commissioner's decision to institute proceedings against a legal practitioner is a discretionary one[6] to be exercised in accordance with the Commission's role as the independent regulator of the legal profession.
