BT's appeal dismissed for the main period (1 October 1978 – 31 March 1989).
The Old Scheme was an exclusive remedy; no unjust enrichment; no mistake of law that would justify a claim outside the scheme.
HMRC's cross-appeal allowed for the 9-month period (1 January 1978 – 30 September 1978).
BT's claim for this period failed because, even if there was a mistake, the claim would engage s.80 VATA 1994, which excludes other remedies, and that claim was already struck out.
