- Delhi Bottling Company was discharging trade effluents from its factory into the Yamuna River under a consent order from authorities. - The Central Pollution Control Board filed a complaint alleging the company was not treating effluents according to standards and a sample showed non-compliance. - A magistrate ordered the company to stop discharges until building treatment and complying with standards. The company appealed, arguing sample collection did not follow proper procedure. - The High Court set aside the order, finding sample analysis was not from the proper laboratory as required by law, so conclusion of non-compliant discharges was not sustainable.
