OTS/NS shall automatically stand revoked unless further period for payment is expressly granted by the bank. So, it speaks only about revocation but nowhere it is stated that in default, bank is entitled to claim original amount. When bank already initiated legal proceedings and filed OA, which was pending by the date of this letter dated 21.2.2018 and if bank is really intended to claim entire amount in case of default, it should have definitely incorporated such a condition in the said letter dated 21.2.2018 and without such express condition, it is not open to the bank now to contend that they are entitled for OA claim. Normally in One Time Settlement cases, default clause as mentioned in the case of EXIM Bank would appear. When such normal condition is not incorporated and letter dated 21.2.2018 refers it as OTS/NS, it has to be inferred Terms indicated in letter dated 21.2.2018 are negotiated Settlement Terms, for which, both parties agreed and signed. Therefore, contention of bank cannot be accepted.
