- The case involves the VAT liability of Invisalign clear aligners supplied by Align Technology Switzerland GmbH and Align Technology BV.
- Aligners are removable orthodontic appliances used to correct misaligned teeth and improve bite functionality.
- Align treated the aligners as exempt supplies of dental prostheses under the Value Added Tax Act 1994.
- HMRC decided that the aligners were subject to VAT at the standard rate, leading Align to appeal.
- The main issue was whether the aligners qualify as dental prostheses under the relevant VAT legislation.
- The tribunal ruled that the aligners are dental prostheses for VAT purposes, allowing Align’s appeal.

- There is a growing trend towards purposive interpretation of statutes, moving away from overly literal interpretations that were previously common.
- This shift has been described as a departure from what Lord Hoffmann referred to as the “dark ages of word magic.”
- In the current tribunal decision, the purpose of the exemption was key to achieving a sensible outcome based on common sense.
