A dispute over value added tax, Han and Yau v Commissioners of Customs & Excise, has reached the Court of Appeal, which has now ruled that an investigation into alleged evasion of VAT should be treated as a criminal, rather than civil, inquiry. Under the European Convention on Human Rights, the company under inquiry is therefore automatically entitled to legal aid, not at the point where there is a court summons, but when Customs & Excise - or the other two agencies - say they plan to pay a call.
