The Court of Appeal in the case of Hong Yik Plastics (M) Sdn Bhd v. Ho Shen Lee (M) Sdn Bhd & Anor [2020] 1 MLJ 743 at p. 749 decided as follows: “[11] In both civil and criminal cases rights exist and are being adjudged. In each the same inherent and constitutional rights exist. In each the duty of the trial judge is the same. In each the parties are entitled to justice under law. Concomitant with this is the trial judge’s duty to determine and apply the law applicable to the facts found. To the lowest and humblest, to the weak, the poor, and to the strong, the same law applies. To be equally administered by a judge. However, justice does not exist in substantive law alone. Justice in the application of substantive law is dependent on the pre-existent fairness of the procedure; in other words, procedural due process in the trial of the cause. Procedural due process is not only for the parties, but, also, for the court itself. Only thereby can the court maintain its conscience and dignity. Only thereby can it appeal to, and justify the trust and confidence of the public. [12] Under our system of adversarial trials, the only participant impartially seeking the true facts and the applicable law is the trial judge. To achieve his purpose and objective in a just manner and with just results, the trial judge is under a duty to see that justice is done; by rendering to every person his due under the same law, equally, fairly, and impartially applied and administered, without bias, without prejudice, without passion, and irrespective of race, creed, economic or social status. In this connection, the duty of the trial judge extends to the preservation of the rights of litigants and a proper disposition of the matters in dispute. It is also the trial judge’s duty to, inter alia: protect witnesses from irrelevant, improper or insulting questions; allow them to be detained only so long as the interests of justice require; allow them to be examined only as to matters legal and pertaining to the issue; advise them of their right not to give an answer which will tend to incriminate them or one which will directly tend to degrade their character, unless it be the fact in issue or a fact from which the fact in issue would be presumed. [13] Accordingly, when the parties have finally arrived at trial, they are entitled to, and it is the trial judge’s duty to give them and to their cause, the calm and deliberate hearing, consideration, and study that the ideal of justice demands. A trial judge must treat lawyers, litigants and witnesses with respect and must refrain from comments that suggest that he has made up his mind in advance.”
