Limitation, exemption and recovery-rule substitution in central excise were tested on wagon manufacture and appellate jurisdiction.

Part of the duty demand was barred by limitation because the show cause notice did not justify the extended period for that portion, so relief was granted on time bar. Exemption under Notification No. 120/75-CE was denied because the wagons were complete units mounted on wheel sets and the invoice value condition required the full commercial value of the article, including components supplied free by the customer. Exemption under Notification No. 119/75-CE was also denied because the activity was not mere job work but full manufacture of wagon bodies and wagons. The appellate authority could not substitute Rule 10A for Rule 10 at the appeal stage, but proceedings validly begun under a subsisting rule survived its repeal or substitution absent an express saving clause.

Issues: (i) whether the demand was barred by limitation for part of the period; (ii) whether the appellants were entitled to exemption under Notification No. 120/75-CE dated 30-4-1975; (iii) whether the appellants were entitled to exemption under Notification No. 119/75-CE dated 30-4-1975; (iv) whether the Appellate Collector could invoke Rule 10A in place of Rule 10 at the appeal stage; and (v) whether proceedings initiated under Rule 10 or Rule 10A survived after 6-8-1977 in the absence of a saving clause.

Issue (i): whether the demand was barred by limitation for part of the period

Analysis: The show cause notice, on its wording and the period covered, did not justify the longer period for the relevant part of the demand. The limitation objection was accepted for the period identified in the notice.

Conclusion: The demand for the relevant part of the period was barred by time and the appellants succeeded on this issue.

Issue (ii): whether the appellants were entitled to exemption under Notification No. 120/75-CE dated 30-4-1975

Analysis: The goods cleared were complete wagons mounted on wheel sets, not wagon bodies alone. The notification required compliance with the condition that the invoice value represent the full commercial price of the article. The value of the article was held to be its intrinsic value, including the value of components supplied free by the customer, and not confined to the amount actually charged by the manufacturer.

Conclusion: The appellants were not entitled to exemption under Notification No. 120/75-CE.

Issue (iii): whether the appellants were entitled to exemption under Notification No. 119/75-CE dated 30-4-1975

Analysis: The activity was not mere job work. The appellants manufactured wagon bodies and fabricated the wagons with wheel sets and other materials, so the process did not fall within the notification's concept of job work, which contemplated return of the article after the intended manufacturing process on charge of job work only.

Conclusion: The appellants were not entitled to exemption under Notification No. 119/75-CE.

Issue (iv): whether the Appellate Collector could invoke Rule 10A in place of Rule 10 at the appeal stage

Analysis: Where the proceedings were initiated under Rule 10, the appellate authority could not, at the appeal stage, substitute Rule 10A to extend limitation and sustain the demand on a different basis. That amounted to acting beyond jurisdiction.

Conclusion: The invocation of Rule 10A in place of Rule 10 was not justified and the department failed on this issue.

Issue (v): whether proceedings initiated under Rule 10 or Rule 10A survived after 6-8-1977 in the absence of a saving clause

Analysis: Proceedings validly initiated under a subsisting rule were held to continue despite repeal or substitution of that rule, in the absence of an express saving clause, following the earlier tribunal view applied in the judgment.

Conclusion: The proceedings survived and the appellants failed on this issue.

Final Conclusion: The appellants obtained relief only on the limitation point, while the challenges to exemption, appellate substitution of the recovery rule, and survival of proceedings were rejected.

Ratio Decidendi: A demand initiated under a validly subsisting rule can continue after repeal or substitution of that rule, but an appellate authority cannot enlarge the basis of recovery by substituting a different rule at the appellate stage; exemption notifications must be strictly satisfied on their conditions.
