Regarding the original question of the thread: If the complainant has declared in his affidavit / plaint that his firm is partnership, then in the cross examination you have agitated this part. Now he must provide the proof otherwise his case falls, surely will fall. Payee and complainant link is subjectively essential.
To Mr Vijay Singh: The process would start, at the end you may win, because slowly slowly courts have started understanding this non sense story of loan / blank cheque. But the point is, since you leave out of India, can you handle it. More details can give some idea about approaching high court under 482.
