The decision in In re Harpur's Will Trusts [2] was relied upon for a different conclusion. That case is not binding upon us. But it carries the high persuasive authority of the opinions of Cross J. at first instance and of Lord Evershed M.R., Harman and Donovan L.JJ. in the Court of Appeal. It therefore must have careful and respectful consideration. It arose in this way: a testatrix directed that her residuary estate should be divided between "institutions and associations having for their main object the assistance and care of soldiers, sailors, airmen and other members of H.M. Forces who have been wounded or incapacitated during the recent world wars". On a summons to determine whether that gift was valid - [3] - Cross J., relying upon the Oxford Group Case [4] , said that the fact that the main object of an institution or association is charitable does not mean that it is necessarily established for charitable purposes only, as it might have subsidiary objects which are not charitable and which are not merely ancillary. In the absence of evidence that none of the bodies having the main object specified by the testatrix had any subsidiary non-charitable objects, his Lordship said that he could not hold that the residuary estate must go to exclusively charitable institutions or associations. He also held that the gift was not saved by the Charitable Trusts (Validation) Act, 1954 U.K.. The Attorney-General appealed, in the interest of charity, to the Court of Appeal. The appeal was however limited to the second point above mentioned. There was no appeal as to the first, counsel for the Attorney-General saying, for some reason that is not to me clear, that it was concluded by the decision in the Oxford Group Case [1] . The appeal was dismissed. Whether or not it was rightly dismissed may be arguable academically as a moot point: see the view of the Act that had been taken by Buckley J. in In re Wykes, deceased [2] . However, that question need not trouble us, because, as Gibbs J. has pointed out, s. 102 of the Trustees Act, 1962 W.A. differs from the corresponding English provisions: and its validating effect in the present case, if validation be needed, is not I think doubtful. But is validation needed? I do not think so, notwithstanding what was said by Cross J. and in the Court of Appeal. I do not seek to distinguish the present case from Harpur's Case [3] on purely literal grounds, although perhaps something might be made of the difference between institutions and associations having for their main object charity and a body the main object of which is charity. I say of the decision in Harpur's Case [3] that I do not think that the words "main object" are a term of art. I certainly do not think that the Oxford Group Case [1] made them so. I do not think that it can be said that always they must be taken to predicate other and independent objects. Nor on the other hand do I think that in every case they necessarily predicate other objects that are ancillary to the main object. As I have said, they are ambiguous: and the ambiguity must be resolved by the context of the particular topic. It may be that Cross J. was aware that some associations having as their main object the assistance and care of sailors, soldiers and airmen wounded in war were associations of old comrades having also social or other activities which might on occasions be pursued independently of the main object. However that may be, that his Lordship gave a meaning to the words "main object" in the will that was before him does not persuade me that the same meaning must be given to them in the statute that is before us. Mrs. Harpur's use of words in her will ought not I think to govern the use of words by the Parliament of Western Australia. Another meaning is open: and I think it is the natural one. I make two further observations about Harpur's Case [1] . It was said by Harman L.J. to be "a tragic case"; for, his Lordship said, "I can feel little doubt that the testatrix meant in effect to benefit members of His Majesty's Forces disabled in the wars of 1914 and 1939". And Lord Evershed said that "had the word "main" been omitted, or the epithet "charitable" been inserted before the various institutions and associations, all would have been well". His Lordship emphasized that, having regard to the concessions made on behalf of the Attorney-General, the sole question for the Court of Appeal was whether the Act of 1954 was applicable. I am not prepared to base any conclusion in the present case upon the proposition, which passed by concession in that case, that the presence of the word "main" there defeated the charitable intent of the testatrix. On the contrary, I would add the case to what MacKinnon L.J. once spoke of as "a number of authorities in most of which the manifest intentions of various testators seem to me to have been defeated by their artless use of language": Re Ward [2] . In the Administration Act the true effect of the words "the main object" is I think to confine exemptions from death duty to gifts to institutions that are charitable, not to enable gifts to institutions that are not exclusively charitable to escape duty.
