“(1) When the Tribunal receives a notice of appeal, application notice or notice of reference, the Tribunal must give a direction allocating the case to one of the categories set out in paragraph (2). (2) The categories referred to in paragraph (1) are— (a) Default Paper cases, which will usually be disposed of without a hearing; (b) Basic cases, which will usually be disposed of after a hearing, with minimal exchange of documents before the hearing; (c) Standard cases, which will usually be subject to more detailed case management and be disposed of after a hearing; and (d) Complex cases, in respect of which see paragraphs (4) and (5) below. (3) The Tribunal may give a further direction re-allocating a case to a different category at any time, either on the application of a party or on its own initiative. (4) The Tribunal may allocate a case as a Complex case under paragraph (1) or (3) only if the Tribunal considers that the case— (a) will require lengthy or complex evidence or a lengthy hearing; (b) involves a complex or important principle or issue; or (c) involves a large financial sum. (5) If a case is allocated as a Complex case— (a) rule 10(1)(c) (costs in Complex cases) applies to the case; and (b) rule 28 (transfer of Complex cases to the Upper Tribunal) applies to the case.”
“[9] We cannot, however, dismiss the possibility of a case which is not complex within the ordinary meaning of that word and yet is one which satisfies one or more of the criteria in rule 23(4). Thus a case might involve no lengthy or complex evidence and may be capable of being dealt with in a short hearing; it might involve no complex or important principle or issue. It might, however, involve what is, on any view, a large financial sum. But the case would not by reason of its high value alone be seen as ‘complex’ within the ordinary meaning of that word. [10] The question then is whether the case can, or should, be allocated as a Complex case. The argument here is that a case which satisfies any of the criteria is at least capable of being allocated as a Complex case; on this approach, the criteria are not simply gateways through which a case must pass before it can be allocated as Complex, but are part of the defining architecture by which the class of Complex cases can be identified. We consider this aspect further at paragraph 29 below.”
“We wish to emphasise the obvious point that not every case allocated as Complex is suitable for transfer to the Upper Tribunal. For instance, a very long Missing Trader Intra-Community case taking many weeks to hear may be inappropriate for transfer (even if it is very complex in nature) for the very reason that its length makes it inappropriate to be heard by the Upper Tribunal having regard to its judicial, estate and financial resources. It would not, therefore, be right to say that before a case could be allocated as a Complex case it must be one which is suitable for transfer to the Upper Tribunal.”
“Notwithstanding the observations in the preceding two paragraphs in relation to costs and transfer, it would not be right to dismiss altogether the consequences of allocation as irrelevant to the meaning of rule 23. The availability of a costs-shifting regime in all cases allocated as Complex and the availability of a transfer to the Upper Tribunal in some cases allocated as Complex (and only in cases so allocated) each inform the interpretation of what is to be seen as appropriate for allocation as Complex. A judge of the Tribunal is entitled to view the case in the round in deciding how to allocate although whether this is part of the exercise of deciding what is capable of being allocated as Complex or is done in the context of the exercise of a discretion to decline to allocate a qualifying case is not clear. For instance, the judge might conclude that the case is the sort of case for which the Upper Tribunal would be an appropriate forum in the light of its legal complexity, recognising at the same time that it might not actually be appropriate to transfer it to the Upper Tribunal for instance because of the length of the hearing required. Or the judge might consider that a case raises a very important issue (bringing the case within rule 23(4)(b)) but conclude that the point is a short one and that not much money is involved (so that the case is not within rule 23(4)(a) or (c)). In deciding whether or not to allocate the case as Complex, we consider that the judge would be entitled to take account of the costs implications of allocating as Complex and to ask himself whether it is really the sort of case where a costs-shifting regime should be available.”
“We accept, of course, that there are limits outside which the Tribunal cannot stray. It would be perverse to say that a hearing of ½ day could ever be lengthy or that a 3 month case was not lengthy. It would be perverse to say a case involving tax of£1,000 involved a large financial sum or that a case involving tax of£100 million did not do so. But in many cases there will a judgment to be made where different judges of the Tax Chamber might reasonably take different views. It cannot be said that there is a single ‘right’ answer that can be objectively ascertained as a matter of law. The Rules assign the task of making that judgment to the Tribunal by providing that a case can be allocated as Complex only if the Tribunal considers one or more of the criteria to be met. We do not consider that there is a single objective and correct answer to how long is ‘lengthy’ or how large is a ‘large financial sum’.”
“… It might, for instance, be said that what is a lengthy hearing for a VAT case is not to be seen as a lengthy hearing in a transfer pricing case; and it might be said that what can be seen as a large financial sum in a personal income tax case might nonetheless properly be regarded as small in the context of dispute concerning petroleum revenue tax. We do not consider that it is appropriate to adopt this refinement. It will lead to complexity and opaqueness in the allocation of cases resulting in an inappropriate use of the resources of the Tribunal (both judicial and financial) with a risk of unnecessary and disproportionate satellite litigation.”
“A further question is whether it is appropriate to take account of the circumstance of the parties in assessing whether a large financial sum is involved. For instance, a given amount of VAT may be very large indeed when viewed through the eyes of a small trader with a turnover of a few hundred thousand pounds, but may be seen as almost trivial when viewed through the eyes of an international corporation with a turnover of hundreds of millions of pounds. We do not consider that, as a general rule, the circumstances of the parties should be taken into account in this way. We say that this should be the general rule because there may be special factors which take a particular case out of the ambit of this general rule. We do not consider it helpful in this decision to attempt to give examples of what might be sufficient to amount to an exception.”
