Extension of Notification Validity: excise notification validity extended to 31st March 1992 by central government in public interest. The Central Government, exercising sub section (1) of Section 5A of the Central Excises and Salt Act, 1944, amends paragraph 2 of Notification No. 193/87 Central Excises by substituting the expiry date '16th day of August, 1989' with '31st day of March, 1992,' thereby extending the notification's validity.
