11. The Code earlier had a specific provision in Order 18 Rule 17A for production of evidence not previously known or the evidence which could not be produced despite due diligence. It enabled the court to permit a party to produce any evidence even at a late stage, after the conclusion of his evidence if he satisfied the court that even after the exercise of due diligence, the evidence was not within his knowledge and could not be produced by him when he was leading the evidence. That provision was deleted with effect from 1.7.2002. The deletion of the said provision does not mean that no evidence can be received at all, after a party closes his evidence. It only means that the amended structure of the Code found no need for such a provision, as the amended Code contemplated little or no time gap between completion of evidence and commencement and conclusion of arguments. Another reason for its deletion was the misuse thereof by the parties to prolong the proceedings under the pretext of discovery of new evidence.

16. We may add a word of caution. The power under Section 151 or Order 18 Rule 17 of the Code is not intended to be used routinely, merely for the asking. If so used, it will defeat the very purpose of various amendments to the Code to expedite trials. But where the application is found to be bona fide and where the additional evidence, oral or documentary, will assist the court to clarify the evidence on the issues and will assist in rendering justice, and the court is satisfied that non-production earlier was for valid and sufficient reasons, the court may exercise its discretion to recall the witnesses or permit the fresh evidence. But if it does so, it should ensure that the process does not become a protracting tactic. The court should firstly award appropriate costs to the other party to compensate for the delay. Secondly the court should take up and complete the case within a fixed time schedule so that the delay is avoided. Thirdly if the application is found to be mischievous, or frivolous, or to cover up negligence or lacunae, it should be rejected with heavy costs.
