Navigation aid exemption denied for DME, while tariff classification issue was remanded for fresh consideration.

Distance Measuring Equipment (DME) was held not to qualify for exemption under Notification No. 284/76-Cus. because its essential character was that of a navigation aid, not an apparatus for wireless reception in a single unit with transmitting apparatus; the fact that it operated through transmission and reception principles was insufficient. On tariff classification, the record showed that the lower authorities had not properly examined the alternative headings suggested for DME, so the matter was remanded to the Collector for fresh consideration of classification. The exemption claim therefore failed on merits, while the classification question was reopened for determination.

Issues: (i) Whether Distance Measuring Equipment (DME) was entitled to exemption under Notification No. 284/76-Cus.; (ii) Whether the matter required remand for consideration of the proper tariff classification of DME.

Issue (i): Whether Distance Measuring Equipment (DME) was entitled to exemption under Notification No. 284/76-Cus.

Analysis: The exemption applied to apparatus for wireless reception in a single unit with transmitting apparatus. DME was found to be primarily a navigation system used for measuring an aircraft's distance from a ground beacon. Its working principle involved transmission and reception, but that alone did not make it the kind of wireless reception apparatus covered by the notification.

Conclusion: The exemption was not available and the claim failed on merits.

Issue (ii): Whether the matter required remand for consideration of the proper tariff classification of DME.

Analysis: The record showed that the lower authorities had not examined whether DME could fall under the alternative headings suggested by the appellants. The majority treated that omission as requiring a fresh examination by the Collector.

Conclusion: The matter was remanded to the Collector for consideration of the proper classification.

Final Conclusion: The exemption claim was rejected, but the dispute on classification was sent back for fresh determination, so the appeal succeeded only to that limited extent.

Ratio Decidendi: A device whose essential character is that of a navigation aid does not fall within an exemption meant for wireless reception apparatus merely because its operation uses transmission and reception principles; where the proper tariff classification has not been examined, remand is justified.
