“13. To put it clear, Order 6 Rule 17 CPC confers jurisdiction on the court to allow either party to alter or amend his pleadings at any stage of the proceedings on such terms as may be just. Such amendments seeking determination of the real question of the controversy between the parties shall be permitted to be made. Pre-trial amendments are to be allowed liberally than those which are sought to be made after the commencement of the trial. As rightly pointed out by the High Court in the former case, the opposite party is not prejudiced because he will have an opportunity of meeting the amendment sought to be made. In the latter case, namely, after the commencement of trial, particularly, after completion of the evidence, the question of prejudice to the opposite party may arise and in such event, it is incumbent on the part of the court to satisfy the conditions prescribed in the proviso.
