The dispute between the parties started surfacing when respondent sent its communication on 7.8.2012 that against the first delivery order, only 5016.230 MT of material could actually be delivered though it had deposited the entire cost for 10,000 tons of material. On such statement, respondent requested the appellant to allow it to deposit payment for purchase of further 10,000 ton of material only on the completion of 100% delivery of the material as per the extended delivery order. Respondent also started extending request for revision of price. Another letter was sent by respondent on 8.8.2012 seeking extension of advance payments. In response to this, the appellant, referring to Clause 12 of the RFQ, suspended dispatches of material stating that respondent had failed to deposit advance payment for second lot of 10,000 tons of material which was required to be lifted in the month of August 2012 and in respect of which, 100% advance payments were to be made on or before 7th August 2012. On 24.9.2012, the appellant required the respondent to deposit Rs.59,29,76,424/- towards amount due for the month of August and September 2012, within 15 days, stating that only upon fulfillment of such requirement, suspension of dispatches may be revoked and respondent may be permitted to lift material against quantity allotted in the month of July 2012. Another letter dated 29.9.2012 was issued by the appellant for depositing payment of Rs.29,64,88,212/- for the month of October, 2012 in the first week of October. Respondent vide its reply dated 1st October 2012 protested that such demands were against the terms of contract. Appellant again sent letter dated 3.10.2012 for making payment of the aforesaid amount for month of October 2012, latest by 6.10.2012. In response, the respondent vide its letter dated 5th and 6th October 2012, raised grievance that such demand was against terms of contract.
