„‟In view of the order of the Delhi High Court prohibiting use of parks for social, cultural, commercial, marriage or other functions and the directions of DPCC dated 13.12.2019 under the Water, Air and EP Acts that no park can be used for social, cultural, commercial, marriage or other functions and the Executive Engineer (Horticulture) of DDA and the MCD will be accountable for the violations, further direction of installing ETP is contradictory as such question does not arise if no such social, cultural, commercial or marriage function is to be held in the parks. This needs to be strictly enforced by the Horticulture Department of DDA and MCD. The DPCC may also modify its directions accordingly and strictly enforce 8 the prohibitions as per orders of Delhi High Court. Similarly, plea of DPCC to depend on amendment by DDA is an attempt to avoid responsibility as even without such amendment powers under the EP Act and the Water Act override any other statute which cannot stand in the way of enforcement of environmental norms particularly in view of orders of Delhi High Court, prohibiting use of parks for such functions.
