"The law has now developed to a point where it may be accepted
that there is a common law duty to act fairly, in the sense of
according procedural fairness, in the making of administrative
decisions which affect rights, interests and legitimate
expectations, subject only to the clear manifestation of a
contrary statutory intention...
Where the decision in question is one for which provision is made
by statute, the application and content of the doctrine of natural
justice or the duty to act fairly depends to a large extent on the
construction of the statute. In Mobil Oil Australia Pty. Ltd. v
Federal Commissioner of Taxation [1963] HCA 41; (1963) 113 CLR 475, at pp 503-504,
Kitto J. pointed out that the obligation to give a fair
opportunity to parties in controversy to correct or contradict
statements prejudicial to their view depends on 'the particular
statutory framework'. What is appropriate in terms of natural
justice depends on the circumstances of the case and they will
include, inter alia, the nature of the inquiry, the subject-matter,
and the rules under which the decision-maker is acting:
Reg. v Commonwealth Conciliation and Arbitration Commission; Ex
parte Angliss Group (1969) 122 CLR 546, at pp 552-553; National
Companies and Securities Commission v News Corporation Ltd.
[1984] HCA 29; (1984) 156 CLR 296, at pp 311, 319-321.
In this respect the expression 'procedural fairness' more aptly
conveys the notion of a flexible obligation to adopt fair
procedures which are appropriate and adapted to the circumstances
of the particular case. The statutory power must be exercised
fairly, i.e., in accordance with procedures that are fair to the
individual considered in the light of the statutory requirements,
the interests of the individual and the interests and purposes,
whether public or private, which the statute seeks to advance or
protect or permits to be taken into account as legitimate
considerations: cf. Salemi v Mackellar (No. 2) [1977] HCA 26; (1977) 137 CLR 396
at 451, per Jacobs J."
