is a contention for the Bank in the counter affidavit, that the petitioner had signed the balance confirmation letter on 06.12.2000, acknowledging the debt, no proof has been produced by the Bank inspite of the fact that the Bank happens to be the custodian of that letter stated as given by the petitioner. In the absence of any proof in support of the said contention, the same can only be treated as a bald one and cannot be accepted or acted upon. Since the averment made by the petitioner that he has not executed any letter of confirmation after April 1998, is not successfully controverted from the part of the Bank by producing requisite material, if any, there is no other alternative for this Court but to draw an adverse inference and to hold it against the Bank that the debt has already become time-barred.
