RAJIB KUMAR PAUL vs GURUDAS MITRA .

The Supreme Court upheld the High Court's decision regarding the unauthorized change of land use from residential to commercial at premises No. 4H, Panchanantala Road, Calcutta, without the necessary sanction from the appropriate authority, violating municipal regulations. The Court emphasized that such unauthorized use cannot be regularized merely by an application for change of use, as it contravenes the provisions of the Calcutta Municipal Corporation Act. The appeals were dismissed, affirming the High Court's order to cease commercial activities in the premises.
