Central Excise Rules amendment reallocates collectors' jurisdictions and replaces 'extend' with 'reduce' in proviso wording. The amendment substitutes items (zd) and (ze) in rule 2 clause (ii)(A) to reassign collector jurisdictions between Calcutta I and Calcutta II and substitutes the word 'reduce' for 'extend' in clause (b) of the proviso to sub rule (1) of rule 176; the rules take effect on publication in the Official Gazette.
