The court noted that no order as to costs of the appeal should be made because the approach to the courts was, in effect, a joint venture by the parties to achieve clarity on an issue of importance to all of them. The court observed that the respondents' approach to interpretation inverted the established interpretative process by first devising a purpose for s 64 and then imposing that devised purpose on the wording of the section. The court commented that evidence from Professor Lucas about practices in the United States regarding freeplay and gambling tax was not only unnecessary for the interpretative exercise, but also irrelevant, as the answer to the issue lies in the interpretation of South African legislation. The court noted that the imposition of gambling and betting tax is a deliberate policy adopted by the Western Cape Provincial Government, entailing the charging of tax on holders of gambling licences for the act of conducting gambling businesses, and there is nothing irrational about such policy.
