The rules concerning the inconsistency of Commonwealth and territory laws have been little explored and largely neglected. They rose to recent prominence in the challenge to the validity of the ACT's same-sex marriage laws. The ACT claimed that even if the Commonwealth's Marriage Act was intended to cover the field, the ACT's same-sex marriage law could still operate concurrently with it, because of the different application of inconsistency rules in the ACT. This article considers how inconsistency rules operate in the different territories, what was intended by the ACT inconsistency provision, how the High Court determined the issue, and whether a better explanation can be given for the outcome.

14 The division of inconsistency into categories of ‘direct inconsistency’ (where it is impossible to obey both laws or where one law alters, impairs or detracts from rights, obligations, powers, privileges or immunities conferred by the other) and ‘indirect inconsistency’ (where the Commonwealth law is intended to ‘cover the field’ to the exclusion of State laws) has been criticized. See, eg, Leeming, above n 9, 151-157. However, for the purposes of this article and explaining the distinction raised in the Same-Sex Marriage Case, this artificial distinction will be maintained.

50 Note, however, an alternative argument that if the Commonwealth evinces an intention to cover the field to the exclusion of any State law, then it ‘provides for an immunity from a class of State laws, which immunity would be qualified, altered or impaired by, and is therefore inconsistent with, the operation of a State law within that class’: Leeming, above n 9, 142. Hence a direct inconsistency would apply.

75 Note also the effect of such drafting in relation to the laws of the Northern Territory and Norfolk Island to which the repugnancy doctrine otherwise applies. It would appear to alter that doctrine, because it deals with the operative effect of such laws in the case of inconsistency, rather than the power to make and sustain the laws.
76 See, eg, Insurance Acquisitions and Takeovers Act 1991 (Cth) s 70. See also, for slightly different wording, s 5E of the Corporations Act 2001 (Cth): ‘The Corporations legislation is not intended to exclude or limit the concurrent operation of any law of a State or Territory.’
77 Compare the situation in Norfolk Island where Commonwealth laws are not intended to apply to Norfolk Island at all unless expressly so applied.
78 See also Quarantine Act 1908 (Cth) ss 87(1C), (1D).
79 Compare Parliamentary Entitlements Act 1990 (Cth) s 10(2), which deals with a clash between regulations and the determinations of the Remuneration Tribunal: ‘[w]here the regulations are intended to cover the whole field in relation to a particular subject matter, then … any provision of a determination that deals with that subject matter is taken to be inconsistent with the regulations, whether or not they are capable of operating concurrently.’ This appears to add more clarity to the position than most other provisions.
80 Note, however, that s 29 of the Norfolk Island Act 1979 (Cth) still uses the terminology of ‘invalidity’, so it is unclear whether it has made this switch. The other acts all refer to inconsistency and the effect of the law.
