Civil Procedure Code, 1908 — Or. 41 R. 27 — Admissibility of additional evidence in appellate court not adduced in the court of original jurisdiction:

Admissibility of additional evidence under Or. 41 R. 27 CPC does not depend upon the relevancy of the issue on hand, or whether the applicant had an opportunity for adducing such evidence at an earlier stage or not, but it depends upon whether or not appellate court requires the evidence sought to be adduced to enable it to pronounce judgment or for any other substantial cause. That is, whether such additional evidence has a direct bearing on pronouncement of the judgment. Para 7 and 8
