Madras High Court (Division Bench of Dr. Justice Anita Sumanth and Justice Mummineni Sudheer Kumar; order pronounced by Mummineni Sudheer Kumar, J.), W.P.No.16030 of 2015, decided 29.01.2026 — Writ petition under Article 226 by Mrs. Shantha Srinivasan (widow of a retired Brigadier, aged 84 at filing, now 94) seeking quashing of the notification dated 06.04.2015 issued by the Member Secretary, CMDA in Ref.No.:VI(1)/89/2015 (Tamil Nadu Government Gazette No.15 dated 15.04.2015) reclassifying New Door No.86/Old Door No.89, Chamiers Road (Pasumpon Muthuramalingam Road), Mylapore, R.S.No.3915/6, from Primary Residential Use Zone to Mixed Residential Use Zone — the culmination of her about one-and-a-half-decade contest against respondents 6 to 9's unauthorized hotel construction on the adjoining plot (earlier rounds: W.P.Nos.17770/2010, 31088/2012, 5583/2013, 11664/2014, 5647/2014 and Review Application (Writ) No.176 of 2014; notice dated 09.04.2012 under Section 56(2) of the Tamil Nadu Town and Country Planning Act, 1971; first respondent's appeal dismissal dated 26.09.2013 with three months to restore per PP No.D8/5170/2010 dated 23.11.2010; R11 Sekhmet Club impleaded 03.04.2024 in W.M.P.No.3637 of 2024). HELD: (i) per Regulation 6(7) of the Development Regulations for the Chennai Metropolitan Area (originally approved under G.O (Ms) No.190, H & UD Department, dated 02.09.2008), sites in Primary Residential Use areas abutting and gaining access from roads of width 12 m and above but less than 18 m are deemed zoned Mixed Residential Use; the disputed plot admittedly abuts and accesses a road wider than 12 m and less than 18 m (the second respondent's uncontroverted 2015 counter-affidavit records width varying 13.80 m to 18.80 m), so the deemed zoning subsists even without the notification and interference would be futile; (ii) alleged infirmities — composition of the second respondent's Board at its 24.12.2014 meeting, non-application of mind by the Technical Committee/Board, absence of personal hearing and non-consideration of written objections — though found to have 'some substance', were expressly not examined; (iii) the explanatory note to the notification itself shows an existing construction in violation of the approved plan requiring demolition or fresh approval, the structure being under 'Lock and Seal' by the third respondent for several years. Writ petition dismissed, no costs, subject to directions: respondents 6 to 9 may construct anew or put the existing construction to use only strictly within the approved plan and applicable rules; respondents 2 and 3 to strictly ensure compliance; any violation allowed to be put to use to be treated as contempt of court, exposing respondents 6 to 9, their successors-in-interest, and respondents 2 and 3 to straightaway contempt liability.
