‘… to enable the full hearing to be listed for an appropriate length of time given the number and identity of the witnesses that need to be called to give evidence. If there are, say, ten witnesses called by HMRC dealing only with the VAT Loss Issues and the appellant wishes to leave open until the final hearing the possibility of cross-examining each of them, then it is necessary to list the hearing both (1) for the length of time necessary to allow for that cross- examination and (2) on dates (at least potentially) that take into account their availability. If the appellant decides at or just before the hearing that it is unnecessary to cross-examine any of them, or only some of them, or on only very limited parts of their statements, then this risks wasting the time of the parties and the tribunal, leading to the possibility of void days in the hearing if witnesses scheduled to be heard later, under the original timetable, are unavailable on any earlier date.’
