MODVAT credit restrictions upheld where the rule permits notification-based conditions on specified inputs under the delegated scheme.

Rule 57-A of the Central Excise Rules, 1944 was construed as permitting the Central Government to specify eligible final products, the duty on inputs, and the conditions and restrictions for MODVAT credit by notification. The absence of the words "as may be specified" in relation to inputs did not render Notification No. 177/86-C.E. ultra vires, because the rule had to be read as a whole and did not confer an unrestricted right to credit on all inputs. As no repugnancy with the parent rule was shown, the restriction to specified inputs was upheld and the challenge failed.

Issues: Whether Notification No. 177/86-C.E. dated 1st March 1986, restricting MODVAT credit to specified inputs, was ultra vires Rule 57-A of the Central Excise Rules, 1944.

Analysis: Rule 57-A was read as authorising the Central Government to specify the final products eligible for MODVAT credit, the duties on inputs for which credit could be allowed, and the conditions and restrictions to be imposed by notification. The absence of the words "as may be specified" in relation to inputs did not make the notification inconsistent with the rule, because the provision had to be construed as a whole and the scheme did not confer an unrestricted right to credit on all inputs. A delegated rule can be struck down only if it exceeds the parent statute or is repugnant to it, and no such inconsistency was established here.

Conclusion: The notification was held to be within the scope of Rule 57-A and not ultra vires. The challenge to the restriction on specified inputs failed, and the assessee was not entitled to credit on all inputs.

Final Conclusion: The writ appeals failed, and the impugned restriction on MODVAT credit was upheld as valid subordinate legislation under the rule-making framework.

Ratio Decidendi: A notification issued under a delegated rule is valid where it operates within the parent rule's scheme and may lawfully restrict a statutory benefit to specified inputs if the rule authorises conditions and restrictions by notification.
