Case Note & Summary
The petitioners, three individuals, filed a writ petition under Article 226 of the Constitution seeking a writ of mandamus to direct the Chennai Metropolitan Development Authority (first respondent) and the Commissioner, Greater Chennai Corporation (second respondent) to perform their statutory duty under Section 56 of the Tamil Nadu Town and Country Planning Act, 1971. They sought restoration of land in Town Survey Nos. 5/7 and 6/1, Athipet Ward, Ambattur Taluk, Chennai District, to its original condition by demolishing an unauthorized lab building constructed by the third respondent, Green Valley Educational Trust, which runs Green Valley Central School. The construction, consisting of a ground plus first floor lab building, was erected without obtaining planning permission from the authorities and had setback violations. The Greater Chennai Corporation had already locked and sealed the lab building in 2013 after issuing proper notice under Sections 56 and 57 of the Act. Despite this, the unauthorized structure remained, prompting the petitioners to seek judicial intervention to compel demolition. The school management had previously petitioned the Department of Housing and Urban Development seeking de-sealing, citing the needs of 900 students and 57 staff, and claimed unawareness of the violation, promising to demolish after building an alternate lab. The court, after considering the status report filed by the Zonal Officer, Zone VII, found that the lab building was wholly unauthorized and that the sealing action had been lawfully taken. The core legal issue was whether the authorities could be compelled by mandamus to complete the enforcement process. The court held that once an unauthorized construction is identified and sealed following due notice under Sections 56 and 57, the planning authority is duty-bound to proceed with enforcement action by demolition. Accordingly, the writ petition was allowed, and the second respondent was directed to demolish the unauthorized lab building within six weeks of receiving the order copy. No costs were awarded.
