at 16% for the suit loan etc., with reference to the same, the necessary particulars and materials on the side of the plaintiff are lacking. On the other hand, PW1 examined on behalf of the plaintiff has admitted that the interest for the loan availed by the defendants is only 13.5% simple interest. In such view of the matter, when there is no acceptable and reliable material projected by the plaintiff's bank as regards the rate of interest prescribed by the Reserve Bank of India now and then, particularly, as to what is the nature of interest for the suit transaction from 22.03.1994 as fixed by the Reserve bank, when with reference to the same, there is no acceptable and convincing materials put forth on the part of the plaintiff, merely on the vague claim of the plaintiff that it is entitled to fix the rate of interest as fixed by the Reserve Bank of India, as such, cannot be accepted. Particularly, as PW1 has admitted that the rate of interest is only 13.5% per annum simple interest and when the plaintiff's bank has not projected any other convincing materials that it is entitled to claim interest at the rate of 16% per annum other than their bald claim of fluctuating rate of interest as fixed by the Reserve Bank of India, particularly, when there is no material pointing to the same and in particular, when the documents projected by the plaintiff do not point out that the defendants are liable to pay the borrowed sum with interest at 16% per annum, in such view of the matter, the trial Court is fully justified in fixing the rate of interest liable to be paid on the borrowed sum at 13.5%
