so critical to this appeal, consisted of about eight tanks, most of which were used for the purpose of storing petrol, oil and other petroleum products, together with certain related plant and equipment, such as pipes and pumps, which went to make up a petroleum storage terminal at Barclay Crescent, Hastings which was owned and operated by Whitemark Pty. Ltd. ("Whitemark") before the land was transferred into the name of the appellant. There was no dispute on the hearing of this appeal as to the fact that the various tanks and other structures had been properly held to be fixtures, inasmuch as, notwithstanding that they were all, with difficulty because of their size, capable of being detached from the land if somebody was entitled to exercise such a power, they were sufficiently connected to the land to have become an integral part of it. One relevant company, Wickland Oil Terminals Pty. Ltd. ("Wickland Terminals")[3] was said to have obtained a lease of the land and to be the lessee of the land at the time of the transfer and to have the right to remove about half (or thereabouts) of those fixtures as "tenant's fixtures", in particular pursuant to s.28(2) of the Landlord and Tenant Act 1958. Another company Whitemark Rollover Pty. Ltd. ("Whitemark Rollover") was said also to have certain rights (in equity) to detach and remove what were in effect the remaining half of the fixtures pursuant to a complicated transaction, to which reference will be made below, which had led to an assignment by Whitemark of those rights to Whitemark Rollover immediately before the land was transferred. Vopak contended that on a proper understanding of the relevant provisions, including heading VI to the Third Schedule and s.63 of the Act, and the recent High Court decision in Commissioner of State Revenue v. Pioneer Concrete (Vic.) Pty. Ltd.[4], the fixtures were not to be taken into account in assessing the value of the land transferred, although they were at the relevant time fixtures, whereas the Commissioner contended that the very fact that they were fixtures made them part of the estate for the purpose of valuation and, having regard also to the decision in Pioneer Concrete, the interests of Wickland Terminals and Whitemark Rollover should be disregarded for the purposes of assessment.
