Who can make a complaint under the Environment (Protection) Act, 1986?

Section 19 of the Environment (Protection) Act, 1986 lets a court take cognizance of an offence on a complaint by the Central Government or an authority or officer it authorises, and also by any person who has given not less than sixty days' notice of the offence and of the intention to complain. Since 1 April 2024 the adjudicating officer, or an officer authorised by him, may also complain. Each listed complainant is therefore competent, so no single option is the complete answer.
