Capacity determination rules and delegated legislation: reduced production capacity falls under Rule 4, and rules lapse after enabling provision omission.

Where a change in machinery or parameters reduces annual capacity of a hot re-rolling steel mill, Rule 5 of the Annual Capacity Determination Rules does not apply; the reduction is to be determined under Rule 4, and the assessee's position prevails. The Court also held that once Section 3A of the Central Excise Act, 1944 was omitted, the delegated rules framed solely under that provision could not continue to operate because the enabling source of rule-making power had disappeared. Both referred questions were answered against the Revenue and the reference was closed.

Issues: (i) Whether Rule 5 of the Hot Re-rolling Steel Mills Annual Capacity Determination Rules, 1997 applies where change in machinery or parameters results in reduction of annual capacity of production and whether Rule 4 governs such re-determination; (ii) Whether, after omission of Section 3A of the Central Excise Act, 1944, the rules framed thereunder could continue to operate.

Issue (i): Whether Rule 5 of the Hot Re-rolling Steel Mills Annual Capacity Determination Rules, 1997 applies where change in machinery or parameters results in reduction of annual capacity of production and whether Rule 4 governs such re-determination.

Analysis: The capacity-determination scheme was construed with reference to prior tribunal decisions which had held that Rule 5 has no application when a change in machinery leads to reduction in capacity. The reasoning accepted was that Rule 5 was intended to address cases where capacity remains unchanged or is increased, while a reduction in annual capacity is to be dealt with under Rule 4. The Court also noted that the Revenue had not successfully displaced the earlier view adopted in identical matters.

Conclusion: Rule 5 does not apply to a case where change in machinery or parameters reduces annual capacity of production, and the matter falls to be determined under Rule 4. This issue is answered in favour of the assessee.

Issue (ii): Whether, after omission of Section 3A of the Central Excise Act, 1944, the rules framed thereunder could continue to operate.

Analysis: The Court relied on the distinction between repeal and omission and on the principle that where the source of rule-making power is withdrawn by omission of the enabling provision, the delegated rules cannot survive independently. Since the power to frame the relevant rules flowed only from Section 3A, its omission meant the delegated framework had no continuing legislative support.

Conclusion: Upon omission of Section 3A, the rules framed under that provision could not continue to operate. This issue is answered in favour of the assessee.

Final Conclusion: Both referred questions were resolved against the Revenue and the reference was finally closed.

Ratio Decidendi: Where a change in machinery or parameters reduces annual capacity of production, the provision dealing with other capacity changes does not apply; and delegated rules cannot survive once the sole enabling provision conferring rule-making power is omitted.
