after being given a reasonable opportunity of being heard. He is, in addition, entitled to protection from sufficient compliance with the rules of natural justice and the disciplinary procedure provided therefor: see Mohd bin Ahmad v Yang Di Pertua Majlis Daerah Jempol, Negeri Sembilan & Anor [1997] 2 MLJ 361. If the public officer succeeds in so impugning, any order of punishment, an order of dismissal, can be declared invalid or void, and such order being so declared void, is deemed not to have been made at all or is deemed to have been only purportedly made previously. But if the public officer fails to so impugn, any order of punishment remains and there should be no further review on such order of punishment. It cannot be denied further that the disciplining of a public officer by his department head is part of the function of the executive branch of the government and any usurpation by a court will be viewed with something very much more than disfavour even though the Judiciary is the judicial branch of the government as well as an institution which belongs to the people. To repeat, a court intervenes only on the nature and manner of accusation against a public officer as distinct from a consequential punishment as explained above. Just like a professional body being the best tribunal to judge the seriousness of misconduct of its members, in a similar vein, an employer, including a government, is the best person to judge similarly the seriousness of misconduct of an employee.
