Erroneous duty refund limitation: recovery must start within statutory time, while provisional classification finalisation may still sustain later duty demand.

Provisional classification lists for block board were finalised under Heading 44.08 after the classification dispute was settled in favour of that heading, so the challenge to that finalisation failed. Recovery of an earlier duty refund was held time-barred because proceedings under Section 11A had to be initiated within the statutory period from the date of refund, and the later Supreme Court ruling did not extend limitation. The subsequent duty demand for the later period was sustained because it related to provisional assessments later finalised, with no completed refund intervening and the Revenue protected by the pending proceedings and bank guarantee.

Issues: (i) Whether classification lists for block board were provisionally approved and could be finally settled under Heading 44.08 of Chapter 44 of the Central Excise Tariff Act, 1985; (ii) whether the demand for recovery of an earlier refund of duty was barred by limitation under Section 11A of the Central Excise Act, 1944; (iii) whether the subsequent demand for duty for the later period was sustainable.

Issue (i): Whether classification lists for block board were provisionally approved and could be finally settled under Heading 44.08 of Chapter 44 of the Central Excise Tariff Act, 1985.

Analysis: Rule 173B governed approval of classification lists, while Rule 9B provided the procedure for provisional assessment. The prior classification lists for 1986 and 1987 were final, as they were neither provisionally approved nor disputed by the assessee. The lists dated 1-3-1988 and 5-4-1988, and later lists filed in 1989, 1990 and 1991, were either pending in court or expressly approved provisionally. Once the Supreme Court settled the classification controversy in favour of Heading 44.08, the provisional lists were capable of being finalised on that basis.

Conclusion: The provisional classification lists were validly finalised under Heading 44.08, and the assessee's challenge to that extent failed.

Issue (ii): Whether the demand for recovery of an earlier refund of duty was barred by limitation under Section 11A of the Central Excise Act, 1944.

Analysis: The refund paid in 1991 arose from the High Court's direction and was treated as a completed refund, not a merely interim arrangement. Recovery of an erroneous refund had to be initiated under Section 11A within six months from the date of refund, subject only to legally cognisable exclusion of time. The show cause notice dated 6-7-1995 was issued long after the refund and could not be saved by invoking the date of the later Supreme Court decision or the pendency of the classification dispute. The demand was therefore time-barred.

Conclusion: The demand for recovery of the refunded amount was barred by limitation and was set aside in favour of the assessee.

Issue (iii): Whether the subsequent demand for duty for the later period was sustainable.

Analysis: The later period was covered by classification lists that had been approved provisionally and were later finalised after the Supreme Court settled the classification issue. Unlike the earlier refund situation, no completed refund intervened, and the Department was entitled to recover the duty consequences of finalisation of the provisional classifications. The bank guarantee and the pendency of proceedings also protected the Revenue for part of the period.

Conclusion: The demand for duty for the later period was upheld against the assessee.

Final Conclusion: The assessee succeeded on the time-bar issue relating to recovery of the earlier refund, but failed on the classification finalisation and the later duty demand.

Ratio Decidendi: Where duty is recovered as an erroneous refund, proceedings must be initiated under Section 11A within the statutory period counted from the date of refund, and a later final pronouncement on classification does not by itself extend that limitation.
