Jurisdiction of Chief Commissioners revised: specified territorial and departmental jurisdictions reassigned under Customs Act notification. The Central Government, under sub-section (1) of section 4 of the Customs Act, 1962, amends Notification No. 58/97-Cus. (NT) to substitute and insert table entries that reassign territorial and departmental oversight: it pairs specified Chief Commissioners with enumerated Commissioners and locations for Customs and Central Excise, thereby reallocating administrative jurisdiction among Chief Commissioners.
