The High Court in "Sue v Hill" in 1999 did not rely upon the long title or the preamble, which conventionally do not have force of law. But it decided that the effect of the Australia Act 1986 (Cth) was that, at least from the date when the Act came into operation, Britain had become a "foreign power" within the meaning of Constitution section 44(i), so that a parliamentary candidate who had British nationality was ineligible to be a member of the Commonwealth Parliament. (Several more cases of British citizenship, as well as citizenship of other countries, in the Commonwealth Parliament came to light in the 2017–18 Australian parliamentary eligibility crisis.)
