Auxiliary duty amendment expands the exemption schedule by inserting a new notification reference, altering exemption coverage. The Central Government, invoking powers under the Customs Act and the Finance Act and citing public interest, amends Notification No. 24/91 Customs by inserting Serial No. 289 in its Schedule to reference Notification No. 140 Customs dated 22 10 1991, thereby altering the miscellaneous exemption framework for auxiliary duty.
