In oral submissions in this Court, the Commissioner correctly submitted that in the construction of par (d) the use of the term "discretion" was apt to distract from the task of identification of the area of the power conferred upon the Commissioner. There must be sufficient warrant in the text of Div 13, its subject matter, scope and purpose, for action by the Commissioner under par (d) upon a particular consideration[26]. The particular considerations upon which the appellants rely, fairness and reasonableness to them, and absence of "a tax avoidance purpose" and of "a profit shifting motive", are not warranted in the sense just described. These are not considerations which, in the sense explained in Avon Downs[27], should have affected the making of the determinations by the Commissioner under par (d). There is no sufficient warrant in the text of Div 13, its subject matter, scope and purpose, to conclude that the Commissioner was obliged to consider any one or more of the three matters relied on by the appellants (fairness and reasonableness to them in the application of the sub‑section, absence of "a tax avoidance purpose", and absence of "a profit shifting motive"). It follows that those matters cannot present issues for the appeals and particulars would be otiose.
