“11. As far as the trial courts are concerned, the trial courts should allow the parties to adduce the oral and documentary evidence intended to be adduced by them, of course, which appears to be relevant for the purpose of the case. The doors of the trial court should not be closed at this stage, denying the opportunity to any party, to adduce any evidence. When a document is said to be forged and when a party has specifically denied the signature or the thumb impression on that particular document, such party should certainly have an opportunity to send the document to the Handwriting Expert for comparison of the disputed signatures or thumb impression with admitted Signatures or the thumb impressions. Of course, the evidence of the expert is also not conclusive. The court has to examine the entire evidence on record, probabilities of the case, including the evidence of the Handwriting Expert, and on critical analysis, it should come to a conclusion. But at the stage of trial of a case, the trial court must give reasonable opportunity to the parties to adduce evidence. Of course, when the parties are not diligent or intending to protract the litigation, the Court may pass conditional order imposing suitable conditions."
