M.C. Mehta vs Union Of India & Ors

The Supreme Court upheld the authority of the Municipal Corporation of Delhi (MCD) to seal premises misused for commercial purposes under municipal and environmental laws. The Court emphasized the need for accountability among officials and directed a phased sealing process to commence on March 29, 2006, while allowing a temporary extension for traders to cease misuse until June 30, 2006, contingent upon filing affidavits. The judgment reinforced the necessity of enforcing municipal laws to curb illegal commercial activities in residential areas, highlighting the systemic issues of corruption and non-compliance.
