Municipal Corporation Of Delhi vs Ghisa Ram on 23 November, 1966
(7) It has repeatedly been held by the supreme court that the certificate of the Director supersedes the report of the public analyst and is to be treated as conclusive evidence of its contents. The Director is a greater expert and therefore the statute, says that his certificate shall be.accepted by the court as conclusive evidence. For all purposes the report of the public analyst is replaced by the certificate of the Director (See Municipal Corporation of Delhi v. Ghisa Ram, , Chetumal v. State of M.P. and Jagdish Prasad v. State of Delhi, Air 1982 Sc 57). Superseded is a strong Word. It means obliterate, set aside) annul, replace, make void, inefficacious or useless, repeal. The Director's certificate supersedes the report given.by the public analyst. Once superseded it does not survive for any purpose. It will be anamolous to hold that for some purpose it survives and for other purposes.it is superseded".
