This discussion addresses how to incorporate new evidence, specifically an original signature from a registered sale deed, into a previously filed application under Section 151 of the CPC. The original application sought to send documents for CFSL and handwriting expert verification. Options discussed include amending the existing application (if it doesn't change the relief sought), filing a fresh application with the new documents, or withdrawing the current application to file a new one. Submitting additional documents for FSL examination is also mentioned as a possibility.
