Integrated imaging system exemption extended to the whole system where the tube could not function independently.

An integrated Image Intensifier System comprising the control unit, monitor, x-ray module and image intensifier tube was examined for exemption under the relevant notifications. The key principle applied was that a component which cannot function independently and forms part of a complete imaging system should be treated as part of the system as a whole for exemption purposes. On that basis, the exemption was held admissible to the entire Image Intensifier System, not confined to the image intensifier tube alone, and the departmental objection was rejected.

Issues: Whether the Image Intensifier System consisting of the control unit, monitor, x-ray module and image intensifier tube was entitled to exemption under the notifications, or whether the benefit was confined only to the image intensifier tube.

Analysis: The exemption claimed for the system was examined in the light of the earlier decision holding that the image intensifier tube does not function independently without the other components of the imaging system. On that reasoning, the system was treated as a whole for the purpose of the exemption, and the benefit was held available to the entire Image Intensifier System.

Conclusion: The exemption was held admissible to the entire Image Intensifier System, and the department's objection was rejected.

Ratio Decidendi: Where a component cannot function independently and forms part of an integrated imaging system, exemption applicable to the system extends to the whole system rather than being restricted to a single component.
