The State government on Tuesday informed the Karnataka High Court that 564 mineral and packaged drinking water units in the State were functioning without the ISI certification and only 224 such units had ISI certification from Bureau of Indian Standards (BIS).

This information was given to a Division Bench comprising Chief Justice Vikramajit Sen and Justice Aravind Kumar during the hearing on a public interest litigation (PIL) petition complaining that a large number of such units are operating in the State without the mandatory ISI certification.
