18 This process is not necessarily easy. The Centre contends that the Tribunal's examination of the factual and legal basis for making a distinction between the taxation periods in question was deficient. At the least, the Centre argues, the Tribunal in giving its reasons for its decision failed to adequately disclose its reasoning process. For example, both Byrne J and the Court of Appeal, when dealing with the earlier assessment, were at pains to examine in detail not only the evidence but also the findings of fact which could be supported by it. The Tribunal ought to have done the same thing. Moreover, Ms Tanya Cirkovic, the practitioner who appeared before the Tribunal on behalf of the Centre had, as the Tribunal itself acknowledged, provided "most helpful submissions"[8] and "a list of matters which she [that is, Ms Cirkovic] says are adequate to distinguish this case"[9] from the earlier proceeding.[10] Not only this, but the Tribunal noted a lack of controversy about the evidence generally, and accepted that each of the centre's witnesses was a witness of truth. All this points to the conclusion that the Centre had at least an arguable case even if, ultimately, the merits were shown to be with the Commissioner. If so, the Tribunal was required to include in its judgment a considered examination of that case. Despite this, the Tribunal failed to set out the results of its examination, if any, of Ms Cirkovic's list. It also failed to identify the evidence upon which it relied in reaching its conclusion that the present case should not be distinguished from its predecessor. The reasoning behind that conclusion therefore remains unknown.
