Case Note & Summary
Background: The dispute arose from importation of miniaturised switches for use in electronic hearing aids manufactured by the respondent. The appellant, Collector of Customs and Central Excise, challenged a Karnataka High Court judgment that allowed the respondent's writ petition. Facts: The respondent imported reed switches, a newly innovated type of switch, for use in hearing aids. At the relevant time, conventional wafer switches were generally used. The Customs authorities took the view that the respondent's import licence did not cover reed switches and that the respondent was not entitled to the concessional rate of import duty. The respondent filed a writ petition before the High Court, which was allowed. On appeal by the Customs authorities, a Division Bench of the Karnataka High Court again ruled in favour of the respondent. The High Court noted the Customs authorities' stand that the words 'switches, miniauthorised' as component parts of hearing aids should be understood to mean only those types of switches generally used in the manufacture of hearing aids at the time of publication of the Import Policy for 1977, and could not include any other type even if usable. The Division Bench observed that such interpretation overlooked that industry is not static and that there is continuous technical progress therein; new processes, methods, materials and components supersede others. Relying on technical opinion that reed switches would improve hearing aid performance, the High Court held reed switches covered by the tariff entry. It also noted the Customs authorities did not allege diversion of the imported switches to another purpose. Legal Issues: The core question was whether the tariff entry for 'switches, miniauthorised' as hearing aid components should be interpreted statically as on the date of policy formulation or dynamically to include later technological innovations. Arguments: The Customs authorities argued for a static interpretation, limiting the entry to switches generally used when the 1977 Import Policy was published. The respondent contended that reed switches were component parts of hearing aids and should be covered, especially given technical opinion and absence of diversion. Court's Analysis: The Supreme Court agreed with the High Court's reasoning, stating it could not put it better. It held that progress cannot be stifled by an over-rigid interpretation of Import Policy or Customs tariff; both must be read as they stand on the date of importation and whatever is reasonably covered thereby must be allowed to be imported regardless of whether it was not in existence or even contemplated when the policy or tariff was formulated. Decision: The appeal was dismissed. The bank guarantee given by the respondent pursuant to the Supreme Court's order dated 25.3.83 was discharged. No order as to costs.
Headnote
A) Customs Law - Classification of Imported Goods - Tariff and Import Policy Interpretation - Import Policy (1977) and Customs Tariff - The Customs authorities contended that the term 'switches, miniauthorised' as component parts of hearing aids covered only conventional wafer switches generally used at the time of publication of the Import Policy, excluding newly innovated reed switches - The High Court held that such static interpretation overlooked continuous technical progress in industry and that reed switches, which improved hearing aid performance, were covered by the tariff entry - The Supreme Court affirmed, holding that progress cannot be stifled by an over-rigid interpretation and that import policy and customs tariff must be read as they stand on the date of importation and whatever is reasonably covered must be allowed import - Held that appeal dismissed and bank guarantee discharged.
Issue of Consideration
Whether the words 'switches, miniauthorised' as component parts of hearing aids in the Import Policy for 1977 covered newly innovated reed switches or were limited to conventional wafer switches generally used at the time of publication of the Import Policy
Final Decision
The appeal was dismissed. The bank guarantee given by the respondent pursuant to the Supreme Court's order dated 25.3.83 was discharged. No order as to costs.
Law Points
- Import Policy and Customs tariff must be read as they stand on the date of importation
- whatever is reasonably covered thereby must be allowed to be imported regardless of the fact that it was not in existence or even contemplated when the policy or tariff was formulated
- industry is not static and continuous technical progress must be considered
- over-rigid interpretation of Import Policy or Customs tariff stifles progress
