Extension of exemption period: notification expiry date for light commercial motor vehicles moved to March 1988. Amendment substitutes the expiry date in Notification No. 463/86-Central Excises: paragraph 2's '30th day of September, 1987' is replaced by '31st day of March, 1988' under the authority of sub rule (1) of rule 8 of the Central Excise Rules, thereby extending the notification's operative period for light commercial motor vehicles.
