In a series of judgments in August and October 2004, the High Court found that the Migration Act 1958 (Cth) (‘the Act’) unambiguously provides for the indefinite detention of unlawful non-citizens, and that such a law is constitutionally valid. In doing so, a majority on the High Court arguably rewrote the rule book on the operation of Chapter III of the Constitution (‘Ch III’), undermining the majority judgment in Chu Kheng Lim v Minister for Immigration in the process.
This case note focuses primarily on Al-Kateb v Godwin. To the extent that they clarify or expand on the reasoning with respect to the operation of Ch III, reference is also made to Minister for Immigration and Multicultural and Indigenous Affairs v Al Khafaji and Behrooz v Secretary of the Department of Immigration and Multicultural and Indigenous Affairs which were argued at the same time as Al-Kateb, and to Re Woolley; Ex parte Applicants M276/2003 by their next friend GS, which concerned the administrative detention of non-citizen children.
