The question as formulated in the judgment under appeal refers to "lands owned by the partnership". And counsel for the respondents spoke of what he called looking behind the partners' share to the partnership assets. But property is not owned by a partnership. It is owned by the partners. As it is put in Lindley on Partnership, 10th ed. (1935), p. 147, "the law, ignoring the firm, looks to the partners comprising it what is called the property of the firm is their property, and what are called the debts and liabilities of the firm are their debts and their liabilities". The term "partnership property" as used in the Partnership Acts (in the Western Australian Act No. 23 of 1895, s. 34) does not alter this. Nor is it material for present purposes that the Acts (s. 32 of the Act of Western Australia) apply the equitable doctrine of conversion to partnership property. A share in a partnership is the interest that a partner has in the surplus of assets over liabilities upon realization. A partner has no separate interest in any particular part of the partnership property. Yet his interest, subject to the claims of the creditors of the partnership business, is it seems to me not, for present purposes, unlike the interest that an owner of an undivided interest in property has. In my view of the matter, the res in question here is the deceased partner's interest in the lands that the partners owned. The land is the tangible thing by reference to which the quality of that interest must, I think, be determined. Being partnership property in a business conducted in Western Australia, the partner's interest in the land is, as between himself and his representatives and the other partners, personal estate by the law of Western Australia and will devolve accordingly if that law governs its devolution. But that does not, for me, answer the preliminary question, is its devolution governed by the municipal law of Western Australia or by the lex domicilii of the deceased. If A and B be simply co-owners of a tract of land, their interests therein must be considered as immovables. Suppose then that they decide to commence some business as partners for the exploitation of their land, say by cutting the timber on it, or mining for minerals, the land becoming partnership property. I do not see that, for purposes of international law, this transforms the character of their interests in it from immovable to movable. In the same way, if land be bought by persons carrying on in partnership the business of dealing in land so that it becomes part of the stock in trade of their business, as in Darby v. Darby [1] , it seems to me that their interests in it are still interests in an immovable and are to be considered as immovable for the purposes of private international law, although personalty for the purposes of local law. That the lex situs of the immovable, the land, subjects it to the debts of the partnership and provides for the realization of it along with other partnership property on a winding up, does not in my view of the matter affect its quality or that of the partners' interests in it as immovable. That the right of a partner as coowner in equity of land held for partnership purposes remains an interest in land, although for many purposes converted into personalty, is illustrated by the judgments of Neville J. in In re Holland; Brettell v. Holland [2] , of Luxmoore J. in In re Fuller's Contract [3] , of Cussen J. for the Supreme Court of Victoria in Duckett v. Collector of Imposts [4] ; cf. Brannigan v. Brannigan [5] , and see the comments of Mr. Higgins in his book The Law of Partnership in Australia and New Zealand (1963), p. 145. It would, no doubt, be possible for the Legislature of Western Australia to provide that land, locally situate, which is partnership property should for all purposes of devolution be a movable. That would be the converse of the case of In re Cutcliffe's Will Trusts [6] and Re A. S. Crook (Deceased) [7] , where the statutory directions were that a movable should be considered as land. But it has not done so. The provision of the Partnership Act that partnership property is personalty falls short of that.
