e.g;
1. Early pronouncement advisable. Parties to have due notice of the day fixed—When the trial in Court is over, the Judge should 1proceed at once, or as soon as possible to the consideration of his judgment. If the judgment is not pronounced at once, every endeavour shall be made by the Court to pronounce the judgment within fifteen days, from the date on which the hearing of the case was concluded, but where it is not practicable so to do, the Court shall fix a future day for the pronouncement of the judgment, and such date shall not ordinarily be a day beyond thirty days from the date on which the hearing of the case was concluded and also if the judgment is not pronounced within thirty days from the date on which the hearing of the case was concluded, the Court shall record the reasons for such delay and shall fix a future day on which the judgment will be pronounced and in every case the due notice of the day so fixed shall be given to the parties or their pleaders). It is essentially necessary that the judge should proceed to the consideration of the judgement while the demeanour of the witnesses and their individual characteristics are fresh in his memory. He should bear in mind that his first duty is to arrive at a conscentious conclusion as to the true state of those facts of the case about which the parties are not agreed. The oral and documentary evidence adduced upon each issue should be carefully reviewed and considered in the directions.
