furnished a certificate from the Executive Engineer, Panchayat Raj. The tender conditions do not specify who the concerned Executive Engineer is. The contention of the learned Government Pleader and Sri S.Lakshminarayana Reddy, learned counsel for the fourth respondent, is that, since tenders were invited by the Panchayat Raj Department, the concerned Executive Engineer can only mean the Executive Engineer, Panchayat Raj, and not the Executive Engineer R& B. This contention found favour with the learned Single Judge. We, however, find considerable force in the submission of Sri P.Sree Ramulu Reddy, learned counsel for the appellant, that, in the absence of the tender conditions specifying who the concerned Executive Engineer is, and as the certificate submitted by the appellant was obtained from the Executive Engineer R&B, who is also an Executive Engineer employed by the Government of Andhra Pradesh, the said certificate produced by the appellant sufficed, and their financial bid should have been opened for its comparative evaluation with that of the fourth respondent.
