1. The correct approach to tariff classification under the Customs and Excise Act is the three-stage process: (i) interpretation of the meaning of words in the relevant headings; (ii) consideration of the nature and characteristics of the goods; and (iii) selection of the appropriate heading. 2. The intention of the manufacturer or importer and the use to which goods are put are not relevant considerations for tariff classification. What is relevant is the nature, characteristics and properties of the goods. Subjective intention and use can only be relevant in establishing those objective aspects. 3. For multifunctional devices, the principal function must be determined based on objective characteristics. A device's principal function is that without which the device would be useless, and which can operate independently of other functions. 4. A digital satellite decoder that receives, decodes and converts satellite transmissions for display on a television has as its principal function the reception of a television signal, notwithstanding other functions such as conditional access, interactive services and messaging. It is therefore properly classified under Tariff Heading 8528.12.90 as 'reception apparatus for television'. 5. Where the ordinary meaning of words in a statute would lead to absurdity or repugnance to the clear intention of the legislature, courts may interpret the statute so as to give effect to that intention. This applies to tariff items in the Customs and Excise Act. The word 'reproducing' in Item 124.75 should be read as 'reception' to harmonize with Tariff Heading 85.28 and give effect to legislative intention.
