Betfair Pty Ltd v Western Australia
High Court of Australia · 2008
Betfair Pty Ltd v Western Australia (2008) 234 CLR 418
A law banning betting exchanges named no state and favoured no one on its face. It was still protectionist.
The justification stage has since been developed: a majority in Palmer applied structured proportionality to a s 92 burden, including an adequacy-in-balance enquiry. Betfair remains authority for assessing discrimination by practical effect and for testing a claimed purpose against reasonable necessity; it is the analysis around that test which has moved on.
What happened?
Betfair operated a licensed betting exchange from Tasmania. Western Australia amended its Betting Control Act to make it an offence to bet through a betting exchange, and to prohibit publishing a Western Australian race field in the course of business without approval — the latter expressly reaching conduct "in this State or elsewhere", with an exemption for the state's own racing body.
What did the Court decide?
Both provisions were invalid to the extent that they applied to Betfair's interstate operations. Their practical operation protected Western Australian wagering interests from an interstate competitor whose business depended on the internet. The Court did not decide whether protecting racing integrity was the legislation's real object; it held that, even taking that purpose at its highest, a prohibition of this kind was not reasonably necessary to achieve it.
Proposition
What is the principle?
A law neutral on its face may contravene s 92 if its practical effect imposes a protectionist burden on interstate trade and it is not reasonably necessary to achieve a legitimate non-protectionist purpose.
Why does this case matter?
It closes the obvious avoidance route. If discrimination were judged only on a statute's terms, s 92 would reduce to a drafting exercise, and any protectionist end could be reached by describing it generally enough.
The reasonable necessity limb is the part students underuse, and this case shows why it is decisive rather than ornamental: the State's asserted purpose never had to be disbelieved for the law to fail. Note also the form of relief. The Court declined to read the offence provision down, granting declarations that the provisions were invalid in their specified application to Betfair instead — a distinction worth having when a question asks what orders should follow.
Exam and application relevance
Trace who bears the burden in practice and who is relieved of competition, not who the statute names. Where a protective purpose is asserted, you do not need to impugn it: ask what less restrictive measure would have achieved the same end, and whether the law goes further than that. An answer that stops at "the law applies to everyone" has not reached the question.
Check your understanding
The Court never decided whether Western Australia's racing-integrity purpose was genuine. Why did it not need to?
