2. Before 1 September 1977 the respondents, who traded under the name of Globe Agencies, conducted a business of selling lottery tickets, mainly to sporting bodies which use the lottery as a means of raising funds. The form of the lottery was simple; participants would buy tickets and the holders of certain tickets would be entitled to receive prizes. In about September 1977 the respondents were approached by the Surf Life Saving Association of South Australia with a request to design a small machine which could be used to sell the tickets mechanically - i.e., a machine which would yield a ticket to anyone who inserted a twenty-cent coin. The Association, because of its financial commitments, did not wish to buy the machine, but requested the respondents to supply it free of charge. The respondents acceded to this request and did design a machine and supplied it to the Association at no cost. Thereafter, during the period 1 September 1977 to 30 November 1979, the respondents made a number of the machines and supplied them free of charge to various organizations, including the public benevolent institutions, which wished to use them for the purpose of raising funds by the conduct of the lottery. The machines remained the property of the respondents, who serviced them free of charge, and, when necessary, replaced them free of charge. They were supplied on condition, inter alia, that only tickets supplied by the respondents were to be dispensed from the machines. The benefit to the respondents from these transactions was that they tended to increase the demand for lottery tickets, which the respondents sold, at a profit, to the organizations using the machines. It may be added for the sake of completeness that after 1 July 1978 the tickets were sold, not by Globe Agencies, but by a company, Globe Vending Pty. Ltd., which was the trustee of a settlement under which the respondents were beneficiaries. Although it was contended in the courts below that since after 1 July 1978 the tickets were not sold by the respondents, but by the company, the machines were therefore not supplied for the benefit or purposes of the respondents, this argument was not advanced before us, and it is convenient to refer (as I have done) to the sale of the tickets by the respondents and accurate to say that the supply of the machines was for their own business purposes.
