QBE Insurance v Mordue  NSWCA 380
This case (at ) makes the point that delegated legislation gives way to the statute under which it is made where the two are ‘irreconcilably incompatible or inconsistent’12. Delegated legislation includes regulations, rules, by-laws, determinations and instruments made under an Act.
Regulations cannot control what an Act means, but they may be used to ascertain and understand a ‘legislative scheme’. QBE notes that delegated legislation inconsistent with the enabling Act is beyond power13; not simply that it cannot change what the Act means14. iTip – when dealing with delegated legislation in any of its forms, remember its status and pay attention to the wider context.
This case is from Episode 9 of interpretationNOW!
