1. Section 4 of the National Gambling Act 7 of 2004 and s 55 of the Gauteng Gambling Act 4 of 1995 are not in conflict; the former describes the mechanics of placing or accepting bets on any contingency for which a bookmaker is licensed, while the latter prescribes the specific contingencies on which provincial bookmakers may accept fixed-odds bets, and the statutes must be read harmoniously. 2. Under the constitutional scheme of concurrent legislative competence, provincial gambling legislation prevails over national legislation where the national legislation does not satisfy the override conditions in s 146(2) or (3) of the Constitution. 3. 'Sporting event' in s 55 of the Gauteng Act is defined as a ball-game, race, or other athletic or sporting contest, competition or game (including a beauty contest) usually attended by the public; roulette, being expressly defined as a casino game, does not fall within this meaning and cannot be the subject of lawful fixed-odds betting by bookmakers. 4. A bookmaker that offers fixed-odds bets on roulette without a casino licence acts unlawfully under ss 39 and 76 of the Gauteng Gambling Act. 5. A second review application directed at approval decisions does not subsume a first review directed at the lawfulness of prior conduct and a regulator's decision dismissing a complaint, where separate issues remain live.
