RT 12 refund claims can be adjusted through return assessment without a separate application when excess duty was paid.

Rule 173-I permits adjustment of excess duty paid against duty assessed on RT 12 return scrutiny, so a separate refund application is not required. Where the assessed duty is less than the duty already paid, the assessee may take credit for the excess through the return mechanism itself. Failure by the department to make the necessary endorsement or adjustment does not prejudice that entitlement. On this basis, a refund claim made in the RT 12 return was treated as a valid refund claim and as having been made within time, and the limitation objection was rejected.

Issues: Whether a refund claim made in the RT 12 return was maintainable and within time, and whether excess duty paid could be adjusted under Rule 173-I without filing a separate refund application.

Analysis: Rule 173-I contemplates assessment on the basis of the RT 12 return and provides for adjustment of duty paid by the assessee against the duty assessed by the proper officer. Where the assessed duty is less than the duty already paid, the assessee is entitled to take credit for the excess. The provision does not require a separate refund application, and the assessee cannot be prejudiced by the failure of the Superintendent to make the appropriate endorsement or adjustment. On that basis, the claim made in the RT 12 return was treated as a refund claim and was held to have been made within the prescribed time.

Conclusion: The refund was admissible, the RT 12 claim was a valid refund claim, and the objection based on limitation failed in favour of the assessee.

Ratio Decidendi: Under Rule 173-I of the Central Excise Rules, excess duty paid on RT 12 assessment is adjustable through the return itself and a separate refund application is not ; a claim made in the RT 12 return cannot be denied as time-barred where the statutory adjustment mechanism applies.
