Rescission of customs notification revokes earlier exemption under the Customs Act as necessary in the public interest. The Central Government, invoking its statutory authority under the Customs Act and being satisfied that it is necessary in the public interest, rescinds Notification No. 150/83 Customs dated 19 May 1983 by issuing Notification No. 374/85 Cus dated 31 December 1985, thereby withdrawing the earlier miscellaneous exemption.
