M.C. Mehta vs Union Of India (Uoi) And Ors.

The Supreme Court addressed administrative and funding requests from the Central Pollution Control Board (CPCB) regarding the installation of air quality monitoring equipment (SODAR and Fine Particulate Matter Samplers). The Court directed the Union of India to grant necessary additional funds and permitted the CPCB to restrict air quality monitoring at specific Agra locations to 208 days per year for maintenance purposes. The order also provided procedural timelines for replies and compliance in the related Agra Heritage matter.
