The former Federal Court in Bhandulananda Jayatilake v Public Prosecutor [1982] 1 MLJ 83, in the judgment of Raja Azlan Shah AG LP (Acting Lord President of Malaysia) provided more clarity on the considerations involved in appeals against sentence, in the following terms: - “Is the sentence harsh and manifestly excessive? We would paraphrase it in this way. As this is an appeal against the exercise by the learned judge of a discretion vested in him, is the sentence so far outside the normal discretionary limits as to enable this court to say that its imposition must have involved an error of law of some description? I have had occasion to say elsewhere, that the very concept of judicial discretion involves a right to choose between more than one possible course of action upon which there is room for reasonable people to hold differing opinions as to which is to be preferred. That is quite inevitable. Human nature being what it is, different judges applying the same principles at the same time in the same country to similar facts may sometimes reach different conclusions (see Jamieson v Jamieson [1952] AC 525, 549). It is for that reason that some very conscientious judges have thought it their duty to visit particular crimes with exemplary sentences; whilst others equally conscientious have thought it their duty to view the same crimes with leniency. Therefore, sentences do vary in apparently similar circumstances with the habit of mind of the particular judge. It is for that reason also that this court has said it again and again that it will not normally interfere with sentences, S/N R7YL97m3hk6tg1kIoLcz7A and the possibility or even the probability, that another court would have imposed a different sentence is not sufficient, perse, to warrant this court’s interference. For a discretionary judgment of this kind to be reversed by this court, it must be shown to our satisfaction that the learned judge was embarking on some unauthorised or extraneous or irrelevant exercise of discretion. We are far from convinced that any criticism of the learned judge is warranted. He took the course he did, in outweighing the plea of mitigation in favour of the public interest with a desire to uphold the dignity and authority of the law as administered in this country. We agree. That must receive the greatest weight. It is a serious offence to give false testimony, for it is in the public interest that the search for truth should, in general and always, be unfettered. The courts are the guardians of the public interest (see the Exclusive Brethren case [1980] 3 All ER 161, 172).”
