"In our view the relative use of civil or criminal investigation techniques is a matter for Customs and Excise to regulate, weighing the competing calls on their resources, the nature of the frauds suspected and the extent to 20 which criminal or civil investigation techniques are capable of turning up sufficient admissible evidence to satisfy the respective burdens of proof for criminal or civil proceedings. Whether investigators should switch from the civil to the criminal mode, or vice versa, in the course of an investigation, as may happen now in direct tax investigations, seems to us 25 also essentially a matter for the Department, in the light of experience and the views and thoughts of Tribunals as to fairness to the accused in the circumstances of a particular case."
“…I consider that for the purpose of determining the jurisdiction of the FTT to deal with arguments as to abuse of process, cases of alleged abuse of process can be divided into two broad categories. The first category is where the alleged abuse directly affects the fairness of the hearing before the FTT. The second 35 category is where, for some reason not directly affecting the fairness of such a hearing, it is unlawful in public law for a party to the proceedings before the FTT to ask the FTT to determine the matter which is otherwise before it. In the first of these categories, the FTT will have power to determine any dispute as to the existence of an abuse of process and can exercise its express powers (and any 40 implied powers) to make orders designed to eliminate any unfairness attributable to the abuse of process. In the second category, the subject matter of the alleged abuse of process is outside the substantive jurisdiction of the FTT. The FTT does not have a judicial review jurisdiction to determine whether a public authority is 11 abusing its powers in public law. It cannot make an order of prohibition against a public authority.”
“[Counsel for the taxpayer] is not making any complaint as to how HMRC have conducted the litigation from the point at which the appellants notified their appeals to the Tribunal. He is, therefore asking the Tribunal to punish HMRC for what the appellants considered to be unacceptable delay before Tribunal 30 proceedings were commenced. I do not consider that would be a proper exercise of case management powers… [Foulser] dealt with a situation where HMRC were argued to have taken certain prejudicial actions while proceedings before the Tribunal were current…”
“However, as the cases above indicate, that is but a starting point. There are cases in which the consequences are so serious, or the nature of the claim as such, that the imposition of a criminal standard of proof is required. There is no 5 binding authority directly on point in relation to income tax penalties, but there are pointers elsewhere in the authorities.”
