Misuse of blank Vakalatnama bearing the signature of one client

Eg. Ram and Sham are known to each and Ram has earlier also helped the father of Sham in one bail case. Few years later Ram was undergoing medical treatment and Sham approached Ram and got 2 blank Vakalatnamas signed from him by misrepresentation, stating that he might need it for his father's case. Few months later Ram receives a court summon in one civil matter and then from the court record it comes in his knowledge that Sham has jointly with Ram engaged an Advocate by using his previously signed blank Vakalatnama in some other case and not in the same bail case. Thereafter, Ram finds out that Sham has jointly submitted a false written statement in the civil suit and the said written statement is bearing the signature and Affidavit of Sham. Ram informs the court in writing and engages a separate counsel and submits his genuine written statement. The said statement gets opposed stating that under order 8 rule 9 cpc second statement cannot be filed. Now that Ram has been stranded and the counsel does not want to reveal the facts as he is a close associate of Sham. The court is of the opinion that legally Ram has to stick with the first written statement which actually is not of Ram. Is there any legal remedy and get the false written statement null and void. Ram has already moved an application in the same civil suit that his misused Vakalatnamas and written should be declared null and void. Are there any legal points that can be used during consideration
