In the Federal Court case, Akira Sales & Services (M) Sdn Bhd v. Nadiah Zee Abdullah & Another Appeal [2018] 2 CLJ 513; [2018] 2 MLJ 537, the liberal approach on judicial review in R Rama Chandran v. The Industrial Court of Malaysia & Anor [1997] 1 CLJ 147; [1997] 1 MLJ 145 has been re-emphasised at pp. 547 to 548 (CLJ); pp. 571 to 572 (MLJ) as follows: “[45] In the same appeal, Edgar Joseph Jr FCJ (Eusoff Chin in agreement) said that an award could be reviewed for substance as well as for process: It is often said that judicial review is concerned not with the decision but the decision making process. (See eg Chief Constable of North Wales Police v. Evans [1982] 1 WLR 1155). This proposition, at full face value, may well convey the impression that the jurisdiction of the courts in Judicial Review proceedings is confined to cases where the aggrieved party has not received fair treatment by the authority to which he has been subjected. Put differently, in the words of Lord Diplock in Council of Civil Service Unions & Ors v. Minister for the Civil Service [1985] AC S/N Vtbw6apI/UKrcl9bZBJzxw 374, where the impugned decision is flawed on the ground of procedural impropriety. But Lord Diplock’s other grounds for impugning a decision susceptible to Judicial Review make it abundantly clear that such a decision is also open a challenge on grounds of ‘illegality’ and ‘irrationality’ and, in practice, this permits the courts to scrutinise such decisions not only for process, but also for substance. In this context, it is useful to note how Lord Diplock (at pp. 410- 411) defined the three grounds of review, to wit, (i) illegality, (ii) irrationality, and (iii) procedural impropriety. This is how he put it: By ‘illegality’ as a ground for Judicial Review, I mean that the decision maker must understand correctly the law that regulates his decision making power and must give effect to it. Whether he has or not is par excellence a justiciable question to be decided, in the event of dispute, by those S/N Vtbw6apI/UKrcl9bZBJzxw persons, the judges, by whom the judicial power of the state is exercisable. By ‘irrationality’, I mean what can by now be succinctly referred to as ‘Wednesbury unreasonableness’ (see Associated Provincial Picture Houses Ltd v. Wednesbury Corp. [1948] 1 KB 223). It applies to a decision which 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. Whether a decision falls within this category is a question that judges by their training and experience should be well equipped to answer, or else there would be something badly wrong with our judicial system. To justify the courts’ exercise of this role, resort I think is today no longer needed to Viscount Radcliffe’s ingenious explanation in Edwards v. Bairstow [1956] AC 14, or irrationality as a ground for a court’s reversal of a decision by ascribing it to an inferred though undefinable mistake of law by the decision maker. ‘Irrationality’ by now can S/N Vtbw6apI/UKrcl9bZBJzxw stand on its own feet as an accepted ground on which a decision may be attacked by Judicial Review. I have described the third head as ‘procedural impropriety’ rather than failure to observe basic rules of natural justice or failure to act with procedural fairness towards the person who will be affected by the decision. This is because susceptibility to judicial review under this head covers also failure by an administrative tribunal to observe procedural rules that are expressly laid down in the legislative instrument by which its jurisdiction is conferred, even where such failure does not involve any denial of natural justice. Lord Diplock also mentioned ‘proportionality’ as a possible fourth ground of review which called for development.” See also: Minister of Home Affairs, Malaysia v Persatuan Aliran
