however, like to sound a note of caution. Expression of general agreement with the findings recorded in the judgment under appeal should not be a device or camouflage adopted by the appellate court for shirking the duty cast on it. While writing a judgment of reversal the appellate court must remain conscious of two principles. Firstly, the findings of fact based on conflicting evidence arrived at by the trial court must weigh with the appellate court, more so when the findings are based on oral evidence recorded by the same Presiding Judge who authors the judgment. This certainly does not mean that when an appeal lies on facts, the appellate court is not competent to reverse a finding of fact arrived at by the trial Judge. As a matter of law if the appraisal of the evidence by the trial court suffers from a material irregularity or is based on inadmissible evidence or on conjectures and surmises, the appellate court is entitled to interfere with the finding of fact. (See Madhusudan Das v. Narayanibai [(1983) 1 SCC 35 : AIR 1983 SC 114] .) The rule is—and it is nothing more than a rule of practice—that when there is conflict of oral evidence of the parties on any matter in issue and the decision hinges upon the credibility of witnesses, then unless there is some special feature about the evidence of a particular witness which has escaped the trial Judge's notice or there is a sufficient balance of improbability to displace his opinion as to where the credibility lies, the appellate court should not interfere with the finding of the trial Judge on a question of fact. (See Sarju Pershad v. Jwaleshwari Pratap Narain Singh [1950 SCC 714 : 1950 SCR 781 : AIR 1951 SC 120] .) Secondly, while reversing a finding of fact the appellate court must come into close quarters with the reasoning assigned by the trial court and then assign its own reasons for arriving at a different finding. This would satisfy the court hearing a further appeal that the first appellate court had discharged the duty expected of it. We need only remind the first appellate courts of the additional obligation cast on them by the scheme of the present Section 100 substituted in the Code. The first appellate court continues, as before, to be a final court of facts; pure findings of fact remain immune from challenge before the High Court in second appeal. Now the first appellate court is also a final court of law in the sense that its decision on a question of law even if erroneous may not be vulnerable before the High Court in second appeal because the jurisdiction of the High Court has now ceased to be available to correct the errors of law or the erroneous findings of the first appellate court even on questions of law unless such question of law be a substantial one.”
