8.1 Introduction
➢ Judges not supposed to decide on merits of AA (whether correct or not)
Cornerstone of dist btw appeal and review
➢ Main reason = SoP
➢ Judge deciding merits of AA → intrusion of judiciary into province of executive
Page 1 of 13
, ➢ Also practical reason for SoP: judges are not qualified to make admin decisions
Administrators are experts in their respective fields and thus their decisions ought to
be respected and carry weight
➢ Reasonableness as ground of review blurs the lines distinguishing appeal and review,
as well as merits and regularity
Decision on whether admin decision is reasonable involves considering merits of
decision but does not involve deciding whether decision is right or wrong
➢ Reasonableness also controversial because it is not absolute
» Some grounds of review are absolute – they are either present or they are not (not
a matter of degree)
- Unlawful delegation or not
- Compliance w. mandatory requirements of empowering legislation or not
➢ Typical challenge to AA:
▪ Person decides to challenge AA because believe was wrongly decided
▪ Usually person attempted to challenge merits of decision using appeal process
▪ Cannot then challenge merits in court if unsuccessful → must find other ground to
challenge decision
▪ If decides to argue on ground of reasonableness → court must det in circumstances
of each case
» Context-specific inquiry
» Line btw reasonable and unreasonable drawn diff depending on circumstances of
each case
Sir Jeffrey Jowell dist 3 diff categories of unreasonableness:
a) Extreme defect in decision-making process
⬧ Assessment focuses on reasoning/ justification for decision (quality of
argument supporting decision)
Decisions taken in bad faith
Decisions based on considerations wrongly taken into account, ignored or
given inappropriate weight
Strictly irrational decisions – inadequate evidence or reasoning to justify
b) Decision taken in violation of CL principles governing exercise of official power
⬧ Unless expressly provided otherwise, principles apply even where discretion
conferred widely
Principles of equality and legal certainty
c) Oppressive decisions
⬧ Unnecessarily onerous impact on affected persons, or
⬧ Means employed are excessive or disproportionate in their result
Quoted w. approval in Ehrlich v Min of Correctional Services case
