4.The learned counsel appearing for the appellant contended that the defendant had borrowed a sum of Rs.50,000/- from the plaintiff on 27.10.2012 and executed Ex.A1/promissory note on the same date. In the said Ex.A1/promissory note, the husband of the defendant and P.W.2/Muthulatha signed as the attesting witnesses. The defendant agreed to pay interest promptly. However, only for six months, the interest was paid and thereafter, the defendant did not pay any interest. Inspite of repeated demands from the plaintiff, the principal amount was not repaid. Therefore, the plaintiff filed O.S.No.476 of 2005. Though expert opinion (Ex.B1) had undermined the case of the plaintiff, the learned counsel for the appellant would contend that any opinion evidence is not conclusive or binding on the Court. It is only a relevant piece of evidence and the Court may come to an independent conclusion in favour of the plaintiff, notwithstanding the adverse opinion of the expert. She would also point out that Trial Munsif adopted the correct approach and that the Appellate Court without assigning any proper or convincing reason reversed the judgment of the Trial Munsif. She would also point out that the plaintiff had filed two other money suits against the defendant, apart from the present suit. She would contend that though all the three suits were decreed and only the impugned judgment and decree passed by the Trial Munsif was put to challenge in the appeal. She pointedly drew my attention to the reason given by the learned Trial Munsif in this regard. The standard defence taken by the respondent herein in all the three written statements was one of denial of the suit transactions and also denial of signatures attributed to her in the promissory notes. The learned counsel also pointed out that the Trial Munsif had specifically observed that the defendant was paying the decreed amount in installments in the execution proceedings. She therefore wanted me to disregard the defence taken in the present second appeal.
