Jurisdiction amendment: operative date for Customs notification deferred, altering commencement of jurisdictional provisions. Amendment substitutes the operative date in Notification No. 63/2002 Customs (N.T.) by exercising powers under sub section (1) of section 4 of the Customs Act, 1962, thereby deferring the commencement date for provisions relating to the jurisdiction of Chief Commissioners, Commissioners, Commissioners (Appeals) and DRI officials appointed as Customs officers; the amendment is procedural and does not change substantive jurisdictional provisions.
