Rebate claim jurisdiction bar: Tribunal cannot hear limitation issues embedded in an appeal over export rebate disputes.

The Tribunal lacked jurisdiction to entertain an appeal arising from a rebate claim covered by the statutory bar in the proviso to Section 35B. Although the Revenue framed the dispute as one of limitation, the issue was embedded in a rebate claim governed by Rules 12 to 14A of the Central Excise Rules, 1944, and the Tribunal could not examine the substantive rebate dispute or ancillary time-bar questions. The appeal was therefore held not maintainable before the Tribunal.

Issues: Whether the Tribunal had jurisdiction to entertain the Revenue's appeal concerning rejection of rebate claim on the ground of limitation.

Analysis: The proviso to Section 35B takes away the Tribunal's jurisdiction in appeals relating to rebate of excise duty on exported goods or on excisable materials used in the manufacture of exported goods. The dispute, though framed by the Revenue as one of limitation, was held to arise out of a rebate claim governed by Rules 12 to 14A of the Central Excise Rules, 1944. Since the Tribunal could not examine the substantive rebate claim, the limitation question embedded in that claim also fell outside its jurisdiction.

Conclusion: The Tribunal had no jurisdiction to entertain the appeal on the rebate-related time-bar issue.

Final Conclusion: The preliminary objection was upheld and the appeal was not maintainable before the Tribunal.

Ratio Decidendi: Where an appeal arises from a rebate claim covered by the statutory bar in the proviso to Section 35B, the Tribunal lacks jurisdiction not only over the rebate claim itself but also over ancillary questions such as limitation that form part of that rebate dispute.
