Jaffa Cakes had been classified as cakes by their manufacturer. Sales tax (VAT) is not charged on biscuits or cakes, but it is charged on chocolate covered biscuits. In 1991 HM Customs and Excise (as HMRC was then called) challenged the classification of Jaffa Cakes. The case went to court and the adjudicator Mr Potter QC judged that Jaffa Cakes are cakes. His brilliant conceptual analysis of cakes and biscuits is supplied here, thanks to the philosopher Tim Crane.
