The Supreme Court upheld the judgments in SKF and International Auto, affirming that interest is payable on differential excise duty with retrospective effect from the first day of the month succeeding the month in which the duty ought to have been paid. The appeals were dismissed, reinforcing the statutory framework of Section 11AB and the Central Excise Rules.

Issues Involved:

1. Correctness of the SKF and International Auto judgments.
2. Effect of the JK Synthetics judgment and other fiscal statute judgments on interest demand.
3. Necessity of duty determination under Section 11A(2) for interest demand under Section 11AB.
4. Impact of Rule 7 of the Central Excise Rules on provisional assessment.
5. Classification of differential duty payment as "short paid" duty.
6. Relevance of income accrual under the Income Tax Act to Section 11AB liability.

Issue-wise Analysis:

1. Correctness of SKF and International Auto Judgments:
The Supreme Court was tasked with resolving whether interest is payable on differential excise duty with retrospective effect under Section 11AB of the Central Excise Act, 1944. The SKF case held that interest is payable from the first date of the month succeeding the month in which the duty ought to have been paid. This was based on the interpretation that the goods carried a higher value at the time of sale, leading to short-payment of duty. The same view was reiterated in International Auto, distinguishing it from the MRF case, which dealt with refund claims and not retrospective price revisions.

2. Effect of JK Synthetics Judgment:
The JK Synthetics judgment established that interest provisions in fiscal statutes are substantive law. The Constitution Bench in JK Synthetics overruled the majority in Associated Cement, emphasizing that interest can only be levied if the statute explicitly provides for it. The Supreme Court in the present case acknowledged this principle but noted that Section 11AB explicitly provides for interest on short-paid duty, aligning with the substantive provision requirement.

3. Necessity of Duty Determination under Section 11A(2):
Section 11A(2) requires determination of duty for interest to be levied under Section 11AB. However, Section 11A(2B) allows for voluntary payment of duty by the assessee before any notice is issued. The Supreme Court observed that SAIL's payment of differential duty without awaiting a notice under Section 11A(1) falls under Section 11A(2B), making interest payable from the first day of the month succeeding the month in which the duty ought to have been paid.

4. Impact of Rule 7 on Provisional Assessment:
Rule 7 of the Central Excise Rules allows for provisional assessment when the value or rate of duty is uncertain. The Supreme Court noted that SAIL should have invoked Rule 7 due to the provisional nature of the prices. The final assessment under Rule 7 would have triggered interest liability from the first day of the month succeeding the month for which the amount is determined, reinforcing the interest liability under Section 11AB.

5. Classification of Differential Duty Payment as "Short Paid":
The Supreme Court examined whether differential duty payment due to retrospective price revision constitutes "short paid" duty. It concluded that short-payment occurs when the initially declared value is provisional and subject to retrospective escalation. The differential duty paid later is indeed short-payment, attracting interest under Section 11AB from the date the duty was originally payable.

6. Relevance of Income Accrual under the Income Tax Act:
The appellants cited income tax cases to argue against interest liability. However, the Supreme Court distinguished these cases, noting that income accrual principles under the Income Tax Act do not apply to excise duty liability under the Central Excise Act. The statutory scheme under the Central Excise Act and the Rules mandates interest on short-paid duty from the date it was originally due, irrespective of when the price escalation is agreed upon.

Conclusion:
The Supreme Court upheld the judgments in SKF and International Auto, affirming that interest is payable on differential excise duty with retrospective effect from the first day of the month succeeding the month in which the duty ought to have been paid. The appeals were dismissed, reinforcing the statutory framework of Section 11AB and the Central Excise Rules.
