The respondent claims that these profits are part of the assessable income of the company either because they are the proceeds of a business carried on by the company within the meaning of that expression in the definition of income from personal exertion in s. 6 of the Income Tax Assessment Act or because they are income within the meaning of one or other or both limbs of s. 26 (a) which provides that the assessable income of a taxpayer shall include profit arising from the sale by the taxpayer of any property acquired by him for the purpose of profit making by sale, or the carrying on or carrying out of any profit-making undertaking or scheme. These provisions were recently considered by this Court in Colonial Mutual Life Assurance Society Ltd. v. Federal Commissioner of Taxation [1] , where it was pointed out that the definition of income from personal exertion does not make all the proceeds of a business income for the purposes of the Act, and that the definition refers only to proceeds which would be held to be income in accordance with the ordinary usages and concepts of mankind except insofar as the Act states or indicates an intention that receipts which are not income in ordinary parlance are to be treated as income. It was also pointed out, as indeed s. 26 (a) plainly states, that the first limb of this section only operates where there is a finding that the purchase was made with the intention of selling at a profit. There is in the present case no evidence capable of supporting a finding that the Lambton Freehold Estate was so purchased. The only possible finding is that the land was purchased in order to carry on coal-mining operations. A small part of the land was sold shortly after it was purchased but coal mining cannot be carried on without coal miners and to make part of the land available for homes for them was to carry out a purpose purely incidental and ancillary to the main purpose. The profits on the sales must therefore be taxable either because the taxpayer was carrying on the business of selling land, in which case the profits would be income on ordinary principles, or because in selling the land the appellant was carrying on or carrying out a profit-making undertaking or scheme in which case the profits would be assessable income under the second limb of s. 26 (a). The inquiry immediately arises when did the appellant first commence to carry on the business of selling land or, what is really the same thing, when did it first commence to carry on or carry out the profit-making undertaking or scheme. It is impossible, I think, to hold that the appellant was engaged in such a business or profit-making undertaking or scheme prior to 1924. The crucial question is therefore whether the facts justify the conclusion that the appellant embarked on such a business or undertaking or scheme in 1924. The facts would, in my opinion, have to be very strong indeed before a court could be induced to hold that a company which had not purchased or otherwise acquired land for the purpose of profit-making by sale was engaged in the business of selling land and not merely realizing it when all that the company had done was to take the necessary steps to realize the land to the best advantage, especially land which had been acquired and used for a different purpose which it was no longer businesslike to carry out. The plain facts of the present case are that the appellant purchased the Lambton lands for the purpose of carrying on the business of coal mining and carried on that business on the land until it was no longer businesslike to do so. It then had the land on its hands and it was land which because of its locality and size could only be sold to advantage in sub-division. A sale in sub-division inevitably requires the building of roads. If it is advantageous to the sale of the land as a whole to set aside part of the land for parks and other amenities, this does not convert the transaction from one of mere realization into a business. It is simply part of the process of realizing a capital asset. The facts are, in my opinion, such that the appellant is entitled to rely on the principles laid down in Hudson's Bay Co. Ltd. v. Stevens [1] and Rand v. Alberni Land Co. Ltd. [2] . The facts in these cases where the court decided in favour of the taxpayer and also in Alabama Coal, Iron, Land and Colinization Co. Ltd. v. Mylam [3] where the court decided the other way were all special to those cases and unlike the present facts in many respects. But the judgments contain important statements of principle. There is the statement in the judgment of the Master of the Rolls in Hudson's Bay Co. Ltd. v. Stevens [1] that he was unable to attach any weight to the circumstance that large sales were made every year. There is also the statement of Farwell L.J. [2] that "a land owner may lay out part of his estate with roads and sewers and sell it in lots for building, but he does this as an owner not as a land speculator it would be different if a land owner, an individual, entered into the business of buying and developing and selling land; but the case of the owner, whether of land, or pictures, or jewels, selling his own property, although he may have expended money on them in getting them up for sale, is entirely different; he sells as owner, not as trader." There is also the statement of Rowlatt J. in Alabama Coal, Iron, Land and Colonization Co. Ltd. v. Mylam [3] , that "in order to see clearly that the Hudson's Bay Case [4] , for instance, does not apply, there must be something in the nature of buying at any rate, and not merely selling, which is mere turning your property into money." His Lordship's statement [5] that "merely realizing is not trading. It is no good saying it is a trade of realizing. But I think what they (the commissioners) mean is: they have taken a process of realizing and embedded it in a trade so that in the course of carrying on a trade they have in fact done some realizing" received the approval of the Privy Council in Commissioner of Taxes v. British Australian Wool Realization Association [6] . In that case the Privy Council pointed out that the mere extensiveness of the organization set up to realize an asset or assets does not of itself cause the realization to become a business. Lord Blanesburgh said that was "a proposition not to be entertained" [7] .
