Madras High Court to Hear Pallikaranai Construction Ban Case on August 3

The Madras High Court has scheduled August 3, 2026, for the final hearing of a case challenging the National Green Tribunal’s (NGT) blanket restriction on construction activities within a one-kilometre radius of the Pallikaranai Marshland in Chennai. The case is being closely watched by the real estate sector as its outcome could influence future urban development across several fast-growing neighbourhoods in the city.

A division bench comprising Chief Justice Sushrut Arvind Dharmadhikari and Justice G. Arul Murugan agreed to hear the matter after senior counsel P.S. Raman, appearing for the CREDAI Chennai Chapter, requested an early hearing. The developers’ body has argued that the NGT’s order has affected thousands of landowners and delayed construction activity across multiple residential and commercial locations.

The disputed order, issued by the National Green Tribunal in September 2025, imposed a blanket restriction on new construction within one kilometre of the Pallikaranai Marshland, a Ramsar site recognised for its ecological significance. According to CREDAI, the restriction covers nearly 3,474 hectares of urban land across localities including Pallikaranai, Velachery, Perungudi, Sholinganallur, Karapakkam, Madipakkam, Perumbakkam and several adjoining areas.

During the proceedings, the Chennai Metropolitan Development Authority (CMDA) informed the court that a large portion of the affected area had already been developed long before the marshland received Ramsar status in 2022. The authority stated that satellite imagery and field verification showed that more than 84 percent of the one-kilometre buffer zone is already occupied by residential and commercial developments.

The CMDA also submitted that dozens of planning permission applications remain pending because of the NGT order. It argued that a fixed one-kilometre construction ban should not continue until scientific studies determine the actual zone of influence around the wetland.

The Tamil Nadu State Wetland Authority echoed this view, informing the court that the Integrated Management Plan and scientific assessments are still under preparation. Officials said the final ecological buffer cannot be predetermined and would depend on hydrological studies, environmental assessments and field verification.

The High Court’s decision in August is expected to provide greater clarity on future planning permissions and could have significant implications for Chennai’s real estate, infrastructure and urban development sectors.
