"24. Learned counsel for the GMB however, would place much c reliance on the tender conditions in which the tenderer agreed that the bidder had made a complete and careful examination to determine the difficulties in matters incidental to the performance of its obligations under the Concession Agreement and to specify the nature and extent of all difficulties and hazards. Counsel would therefore, contend that any difficulty or even impossibility in D obtaining environmental clearances cannot be a defence of the petitioner to avoid forfeiture of the security deposit. We are unable to read such condition in such a rigid manner. If the contract had frustrated on account of impossibility, we have serious doubt whether GMB could forfeit security deposit citing the reason that E whatever be the reason, the petitioner failed to perform its obligations and, therefore, must be visited with the penalty of forfeiture. However, there is an additional reason why we must reject such a contention. We may recall, the initial project was for construction of port at Sutrapada. On account of the respondents not being able to make the land available for such project, the F same had to be shelved. Only as an alternative, the petitioner suggested Kachchigarh as a site where the port could be developed. Surely, the petitioner was not expected tn.carry out complete environmental assessment before coming up with such an alternative suggestion nor GMB understood the offer of the G petitioner as to one which will irrespective of environment concerns, be accepted. When there was a fundamental shift in the initial project envisaged in the letter of intent, the contention that whatever be the difficulties in executing the contract, forfeiture must follow, need to be viewed in the background of such material changes.
