the said document neither bears any date of issuance nor contains a valid UDIN (Unique Document Identification Number), which is a mandatory requirement for certificates issued by a Chartered Accountant. In stark contrast, the turnover certificate annexed by the petitioner at page No. 30 of the writ petition, purportedly issued for the financial year 2024–2025, clearly reflects both the date of issuance as well as a valid UDIN. This material inconsistency between the two documents strongly indicates that the certificate submitted during the tender process is not genuine and appears to be a forged or fabricated document, thereby vitiating the integrity of the bidding process. It is further submitted that the submission of such a document, which prima facie lacks essential authentication details, cannot be brushed aside as a mere clerical or typographical error, as sought to be contended by the petitioner. The absence of a date and UDIN goes to the root of the document’s validity and credibility, particularly in a public procurement process where financial eligibility is determined on the basis of such certificates. He also submitted that the respondent authorities are duty-bound to ensure transparency, fairness, and strict compliance with tender conditions, and any deviation or submission of suspect documents warrants strict action. The explanation offered by the petitioner fails to satisfactorily account for this glaring discrepancy, and therefore, the decision to blacklist the petitioner for a limited period of one year is justified, proportionate, and in furtherance of maintaining the sanctity of the tender process.
