fulfil all the requirements of the tender Clauses 3 to 6 of RFP, being the existing concessionaire of the project, does not exempt the respondent from participating in the tender process; rather the tenor of the terms of the documents made it obligatory for the respondent to participate in the tender process to be considered as a responsive bidder, along with others. Having failed to participate in the tender process and, more so, despite the express terms in the tender documents, validity whereof has not been challenged, the respondent cannot be heard to contend that it had acquired any right whatsoever. Only the entities who participate in the tender process pursuant to a tender notice can be allowed to make grievances about the non-fulfilment or breach of any of the terms and conditions of the tender documents concerned. The respondent who chose to stay away from the tender process, cannot be heard to whittle down, in any manner, the rights of the eligible bidders who had participated in the tender process on the basis of the written and express terms and conditions. At the culmination of the tender process, if the respondent had not participated, in law, the offer submitted by the eligible bidders is required to be considered on the basis of the stated terms and conditions.
