Few cases of recent times, beyond the decisions of Mabo and Wik, could rival Minister for Immigration and Ethnic Affairs v Teoh, for the dramatic response it provoked in political, legal and academic circles. In the aftermath of the High Court's decision in Teoh came three Commonwealth Bills, one state Act, several ‘executive statements’ at both the Federal and state level, and numerous academic commentaries. Yet, despite the many attempts to override the decision by successive federal governments, the Teoh principle continues to apply to the administrative decisions made at the federal level. The third of the Commonwealth Bills aimed at over-riding the Teoh principle of legitimate expectation progressed only as far as its predecessors, with its debate in the Senate having been adjourned on 5 April, 2001.
It is unlikely that enactment of the proposed Bill would have laid the Teoh principle finally to rest, and developments since the last Senate Inquiry conducted in 1997 raise further issues pertaining to the original High Court decision. In particular, subsequent case law has provided clear judicial statements regarding the effectiveness (or ineffectiveness) of earlier executive statements issued by successive federal governments, as well as outlining what constitutes a legally enforceable ‘executive indication to the contrary'. In addition to recent developments on the domestic front, the proposed Bill had also been criticised by one international body for being inconsistent with Australia's international legal obligations, with the recommendation that it be withdrawn. Given the very minor differences between the third Bill and its two predecessors, this charge could also have been laid in respect of each of the earlier Bills.
