“The profits of a trade must be calculated in accordance with generally accepted accounting practice, subject to any adjustment required or authorised by law in calculating profits for income tax purposes.”
“Every natural or legal person is entitled to the peaceful enjoyment of his possessions. No one shall be deprived of his possessions except in the public interest and subject to the conditions provided for by law and by the general principles of international law. The preceding provision shall not, however, in any way impair the right of a State to enforce such laws as it deems necessary to control the use of property in accordance with the general interest or to secure the payment of taxes or other contributions or penalties.”
“Of course, the money is a possession in one sense, but it is a possession impressed with an arguable claim by HMRC, which prevents it being properly regarded as a possession for A1P1 purposes.”
“a disputed amount is not in the taxpayer’s possession if there is an arguable claim by HMRC to it, or if the taxpayer has an arguable claim to it … the prior question of whether the taxpayer has a right to the money must be decided before the taxpayer can claim to have been deprived by the legislative changes of a possession under A1P1.”
“clear binding authority that legislation can remove without any interference with possessions, a taxpayer’s argument that had existed previously (that HMRC was not entitled to the money), with the result that tax is payable and the money in the taxpayer’s hands must fund it.”
“the ultimate question is whether the relevant statutory provisions, construed purposively, were intended to apply to the transactions, viewed realistically.”
