“I think the test, which must be used to determine whether a venture such as we are now considering is, or is not, “in the nature of trade” is whether the operations involved in it are of the same kind, and carried on in the same way, as those which are characteristic of ordinary trading in the line of business in which the venture was made.”
“… it was suggested that the best guide is to view ‘commercial’ as the antithesis of ‘uncommercial’, and I do find that a useful approach. A trade may be conducted in an uncommercial way either because the terms of trade are uncommercial (for instance, the hobby market-gardening enterprise where the prices of fruit and vegetables do not realistically reflect the overheads and variable costs of the enterprise) or because the way in which the trade is conducted is uncommercial in other respects (for instance, the hobby art gallery or antique shop where the opening hours are unpredictable and depend simply on the owner’s convenience). The distinction is between the serious trader, who, whatever his shortcomings in skill, experience or capital, is seriously interested in profit, and the amateur or dilettante.”
