principle enunciated therein, namely that the employer is ordinarily entitled to insist upon strict compliance with essential tender conditions, has no application where the substantive requirement underlying the condition already stands fulfilled. In the present case, the object of Clause 2.2.2.2(ii) of the RFP was to enable the Authority to assess the technical capacity and experience of the bidder. The requisite information for such assessment was comprehensively furnished through the Experience Certificate dated 17.04.2026, duly issued by the client, MSRDC, the authenticity and contents whereof have not been disputed by the respondent no. 2. The respondent no. 2 has also been unable to demonstrate that the PCC would have supplied any additional material information relevant to the evaluation of the bidder’s eligibility. Once the Experience Certificate issued by the client MSRDC had been furnished and the technical credentials of the petitioner stood duly evidenced thereby, the essential requirement of the RFP stood substantially complied with. Moreso, no PCC had in fact been issued by MSRDC prior to 30.06.2026 and, therefore, the petitioner could not have furnished a document which was not in existence at the relevant time.
