Bombay HC (Aurangabad Bench), DB (judgment per Hiten S. Venegavkar J.; reserved 16.03.2026, pronounced 06.05.2026) - W.P. 1935 & 1938 of 2026 (Sai Infrastructure; Krishna Enterprises) dismissed. The two partnership-firm Petitioners, declared highest bidders in e-auctions for disposal of Pond Ash at Bhusawal Thermal Power Station (Mahagenco) - bids of Rs.635/MT and Rs.632/MT plus GST against the old Rs.193/MT rate enjoyed by Respondent No.5 Phoenix's SSPM Ventures - each deposited Rs.10 lakhs security, after which the Respondents cancelled e-auction No.38553 (email 31.01.2026) following an internal inquiry (office order 21.01.2026; report 27.01.2026 finding irregularities in eligibility scrutiny, deviations, EMD treatment, authentication of evaluation sheets, record maintenance and misinterpretation of qualifying requirements) and issued a fresh e-auction notice on 05.02.2026. Petitioners sought quashing of the cancellation and fresh notice and a mandamus to honour the earlier auctions, alleging arbitrariness, non-disclosure of reasons, mala fide preference to Respondent No.5, violation of Article 14 and of the Ash Utilisation Policy, 2025, and breach of the Court's earlier directions in W.P. 8531/2025 (order dt. 19.09.2025) and C.A. 10680/2025 (order dt. 13.10.2025). Held, dismissing both petitions: (i) judicial review of tenders extends only to the legality of the decision-making process, not commercial wisdom (Tata Cellular principle applied; Jagdish Mandal, Michigan Rubber, Caretel Infotech, Silppi Constructions, N.G. Projects, Tata Motors relied on); (ii) a highest bidder acquires no indefeasible or enforceable right before a concluded contract, and security-deposit-backed legitimate expectation yields to legality where the process itself is impaired; (iii) cancellation is sustainable where, on verification of complaints (even from non-participants/disqualified persons), an independent inquiry supplies relevant and bona fide material that process integrity stands compromised, notwithstanding the highest bidder's personal blamelessness; (iv) terseness of the cancellation email is immaterial where the record substantiates the reasons in substance; (v) suspicion of mala fides from the sequence of dates is not proof; (vi) public interest is not reducible to immediate revenue - scrapping and re-tendering a tainted process may itself be a public-interest decision; (vii) Golden Food Products India (2026 INSC 22) and Eva Agro Feeds ((2023) 10 SCC 189) distinguished as turning on the absence of any process defect. Rule discharged; interim relief (order dt. 05.03.2026 restraining auction of 60% Pond Ash) vacated and the post-pronouncement prayer for its continuation rejected; refund/adjustment of the security deposits directed within a reasonable period; no opinion expressed on the comparative merits of the fresh tender conditions or on the private disputes with Respondent No.5.
