Amendment to Commencement Date: notifications defer the operative start of specified central excise exemptions to a later date. Notification No.77/2003-CE amends Notification Nos.58/2003-Central Excise and 59/2003-Central Excise by substituting the figures, letters and words in paragraph 2 to replace the earlier commencement date with a later commencement date, thereby deferring the operative start of the measures in those notifications.
