Section 27. Production of additional evidence in Appellate Court

27. Production of additional evidence in Appellate Court.— (1) The parties to an appeal shall not be entitled to produce additional evidence, whether oral or documentary, in the Appellate Court. But if — (a) the Court from whose decree the appeal is preferred has refused to admit evidence which ought to have been admitted, or 1 [(aa) the party seeking to produce additional evidence, establishes that notwithstanding the exercise of due diligence, such evidence was not within his knowledge or could not, after the exercise of due diligence, be produced by him at the time when the decree appealed against was passed, or] (b) the Appellate Court requires any document to be produced or any witness to be examined to enable it to pronounce judgment, or for any other substantial cause, the Appellate Court may allow such evidence or document to be produced, or witness to be examined. (2) Wherever additional evidence is allowed to be produced by an Appellate Court, the Court shall record the reason for its admission. 27. Service on civil public officer or on servant of railway company or local authority.— Where the defendant is a public officer (not belonging to the[1] [the Indians] military[2] [naval or air] forces[3] *), or is the servant of a railway company or local authority, the Court may, if it appears to it that the summons may be most conveniently so served, send it for service on the defendant to the head of the office in which he is employed, together with a copy to be retained by the defendant. 27. Liability of judgment-debtor discharged.— No order of restitution or discharge under rule 26 shall prevent the property or person of a judgment-debtor from being retaken in execution of the decree sent for execution.
