The Madras High Court has dismissed a petition seeking to prevent the Isha Foundation from conducting Mahasivarathri celebrations at its Coimbatore campus. The petitioner had alleged that the foundation lacked adequate sewage treatment facilities and caused noise pollution. However, the Tamil Nadu Pollution Control Board (TNPCB) informed the court that the foundation has adequate treatment facilities and complies with noise regulations. The court dismissed the petition, allowing the celebrations to proceed.
