Held: (i) the pendency of the possession suit O.S.No.6218 of 2023 (ex C.S.No.309 of 2003) and the prior decrees against the vendor Dr.Ruth Annamalai (TOS.No.15 of 1989 dismissed 11.02.2000; injunction suit O.S.No.4423 of 2007 decreed 18.04.2009) do not bar exercise of the Section 136 power — protecting occupiers, passers-by and the public is a statutory duty; (ii) the fifth respondent, a purchaser pendente lite (registered sale dated 29.03.2012), is bound by those decrees and by any future decree, the alienation attracting Section 52, Transfer of Property Act, 1882 (doctrine traced to Bellamy V. Sabine (1857) 1 De G & J 566); (iii) with the ownership dispute before the civil court and the petitioner's claim on record through representations, the enquiry could not be confined to the purchaser alone — natural justice required notice to and hearing of the writ petitioner and all occupiers; (iv) Sections 136(1) and 136(3) cannot be telescoped into one simultaneous combined order — Section 136(3) operates only upon non-compliance with a Section 136(1) order, otherwise the owner/occupier is deprived of the opportunity to challenge the Section 136(1) order; (v) the impugned order contained no categorical finding and no disclosed reasons — an order bereft of reasons is stillborn (Bhagat Raja v. Union of India, AIR (1967) SC 1606; Basudev Datta v. State of West Bengal & Ors., 2024 INSC 940). Proceedings restored to the Commissioner's file with directions to notify the petitioner, the purchaser and all occupiers, hold an enquiry obtaining a Structural Engineer's report if necessary, and pass a reasoned and detailed order; Assistant Commissioner, Zone V to ensure compliance. Acting under Article 226 the Court cannot itself test structural safety — a statutorily vested power must be exercised by the vested authority. Writ petition allowed, no costs; connected W.M.Ps. closed.
