I agree with the submission of counsel for the Club that it is the land as a whole that is to be considered in determining whether it is used for the purpose of producing assessable income. The question then arises whether it is necessary, under s. 88 (2), that the production of assessable income should be the sole purpose for which the land is used. I think the provision should not be construed so narrowly. The sub-section does not speak of the "sole" or "exclusive" use for the purpose specified and, in my opinion, it should not be construed as though it did. It is, I think, at least sufficient if use for the production of assessable income is the chief purpose for which the land is used (Commissioners of Inland Revenue v. Forrest [1] ) and that requirement is, as it seems to me, fulfilled in the present case. During the relevant periods, the land was used for the purpose of conducting race meetings and this is the first of the objects for which the Club was formed (see Rule 2 (a) of the Rules of the Club). Those meetings are intended to and do in fact attract the attendance of large numbers of the public who pay for admission to the course and for the use of its facilities and in that way contribute in large measure to the Club's revenue. It is true that that part of the total revenue which comes from the subscriptions of members is not assessable income but the proportion is a relatively small one. For example, in the year ending 30th June 1962, members' subscriptions amounted to £9,560 out of a total revenue of £182,572, and to deny that, for that reason, the main purpose for which the land is used is that of producing assessable income seems to me to be unreal. It is true also that one of the objects for which the Club was formed was to promote the improvement of horse-breeding and horse-racing but that seems to me merely to emphasize the primary importance of the Club's income-producing activities. Without them, the other purposes for which the Club was formed would fail. I am of opinion, therefore, that the land demised, looked at as a whole, was used for the purpose of producing assessable income and that this was the chief purpose for which it was used. Leaving on one side, for the moment, the improvements to the five-furlong course, I am of opinion that the Club is entitled to the benefit of s. 88 (2) in respect of the expenditure incurred by it during the relevant years on the improvements effected by it on the course.
