(ii) The Application of the Judicial Review Principles [54] We accept the proposition advanced by learned counsel for the Appellant, though we would frame it with some degree of nuance. We do not hold that a creditor who seeks to challenge the DGI's certificate under section 33B must satisfy every formal procedural requirement associated with a judicial review application. Section 33B provides its own self-contained mechanism for challenge. The creditor does not need to obtain leave, file an originating motion, or comply with the Order 53 Rules of Court 2012 procedure. The legislature has created an avenue for objection, which the creditor may invoke as of right upon receiving the DGI's notice of intention. [55] What we do hold, however, is that the substantive grounds upon which the court may intervene in the DGI's decision under section 33B must be broadly similar to those that ground judicial review. The judicial review framework - illegality, irrationality, and procedural impropriety provides a useful and principled parameter by which to assess whether the DGI has acted within the bounds of lawful and reasonable administrative discretion. It serves as a useful analytical guide aimed at achieving consistency of approach. [56] Although the development of the grounds for judicial review have expanded to also include proportionality, we do not think it is necessary to add it as a fourth limb. The judicial review grounds merely serve as a general guide for the applicable test in determining the exercise of the DGI's discretion. [57] Put simply, before a court may intervene in a section 33B proceeding and make an order under section 33B(6), there must be a threshold that is crossed. That threshold is reached only where the creditor can demonstrate that the DGI, in exercising his discretion to issue the certificate of discharge, acted outside the bounds of lawful and reasonable administrative discretion. Short of that threshold, the court has no proper basis to second guess or override the DGI's judgment, however strongly the creditor may disagree with the outcome. The Three Limbs Applied [58] To provide context, it is perhaps useful for this court to provide illustrations on how each limb of the test to challenge the DGl's decision is to be founded. [59] The first limb is illegality. The DGI acts illegally where he misunderstands or misconstrues the legal parameters of the power he is exercising, acts in excess of that power, acts for an improper purpose, or considers matters which are legally irrelevant or fails to take into account matters which are legally required to be considered. In the context of section 33A, the DGI would cross the threshold of illegality if he were, for example, to issue a certificate of discharge in favour of a bankrupt who has not served the prescribed minimum period, or where he acts on the direction of a third party rather than in the independent exercise of his own statutory discretion, or where he takes into account factors wholly unrelated to the bankruptcy administration. [60] The second limb is irrationality, or Wednesbury unreasonableness, derived from the celebrated English authority of Associated Provincial Picture Houses Ltd v Wednesbury Corporation [1948] 1 KB 223. A decision is Wednesbury unreasonable where it is so outrageous in its defiance of logic or of accepted moral standards that no sensible person who had applied his mind to the question to be decided could have arrived at it. In the context of section 33A, this limb would be engaged where, for instance, the DGI issued a certificate of discharge in circumstances that were manifestly and obviously wrong for example, in favour of a bankrupt who has been consistently uncooperative, who has deliberately concealed assets, or whose estate contains substantial realisable assets that have been wilfully neglected. The irrationality threshold is a high one, and rightly so. It is not mere disagreement with the DGI's weighing of the relevant factors. [61] The third limb is procedural impropriety. The DGI would fall foul of this limb where he has breached a mandatory procedural requirement prescribed by the Act or the rules made thereunder, or where he has acted in breach of natural justice. The rules of natural justice in this context require, at a minimum, that the creditor who objects be given proper notice and a fair opportunity to be heard, and that the DGI bring an open and unprejudiced mind to the exercise of the discretion. The Act itself gives expression to this requirement through sections 33B(4) and (5), which mandate that notice of the DGI's intention be served on known creditors and that they be afforded an opportunity to object. [62] The caveat to the above illustrations is that they are always subject to the facts of each case. Base case, the decision of the DGI must be carefully examined to see if the decision was tainted by any wrongful exercise of his powers. [63] We are of the firm view that anchoring the court's supervisory jurisdiction under section 33B to these three well-established limbs serves several important purposes. First, it provides a principled and coherent standard that is consistent with the broader body of Malaysian administrative law, thereby ensuring that the section 33B jurisdiction does not develop in an arbitrary or unpredictable manner. Second, it gives appropriate respect to Parliament's deliberate choice to vest the primary discharge decision in the DGI an expert administrative officer rather than in the court. The framework prevents courts from substituting their own assessment of the merits for that of the DGI simply because they would have reached a different conclusion. Third, it adequately protects the legitimate interests of creditors by ensuring that a genuinely improper exercise of the DGI's discretion one tainted by illegality, irrationality, or procedural unfairness remains susceptible to curial correction. [64] It must be emphasised equally that this framework does not render the court's supervisory role toothless. Where the DGI's decision is genuinely tainted for instance, where it is shown that the DGI acted under a mistake of law, or was improperly influenced, or reached a conclusion so unreasonable as to defy rational justification the court not only may but should intervene under section 33B. The rehabilitative purpose of section 33A must not be allowed to become a shield for improper or capricious administrative conduct. [65] For completeness, we wish to emphasise that the above considerations would also be applicable to challenges that emanate as a result of the DGI's exercise of discretion under section 33C of the Act.
