A more recent version of these Legitimate Expectations notes – written by Oxford students – is available here.
The following is a more accessble plain text extract of the PDF sample above, taken from our Administrative Law Notes. Due to the challenges of extracting text from PDFs, it will have odd formatting:
INTRA VIRES REPRESENTATIONS Procedural Protection of LE - existence of some process right which C claims to have due to PB's behaviour generating the expectation
C's interest by itself doesn't warrant protection but public body's conduct, through its representation, provides foundation for it o AG of HK v Ng Yuen Shiu - although rules of NJ/fairness don't generally apply to illegal alien, he could claim some elements of fair hearing if he had LE which could arise if govt. announced each would be interviewed
& case treated on merits w/out guarantee of success.
? Elias: LE arising from govt. assurances enabled court to intervene - C's status as illegal immigrant not sufficient in itself
Representation giving rise to LE may supplement C's existing procedural rights o Liverpool Taxi Fleet Operators - council ltd no of licensed taxis, told Cs wouldn't increase without consultation but did. Unclear if would have had rights without rep but, if so, content enhanced by reps. Denning: council ought not to depart from undertaking except after most serious consideration & hearing what Cs have to say, and then only if overriding public interest demands it.
Where PB established criteria for application of policy, C relied on it & PB then seeks to apply a different one, can argue LE o Khan - C sought to adopt brother's kid from Pakistan, HO provided circular stating criteria used by HS, then rejected entry clearance b/c used different criteria instead. Held, whilst no specific undertaking, Liverpool Taxi principle applied. If HS stipulated certain entry conditions, couldn't resile without affording C a hearing
+ only if public interest demanded it. o Schmidt v HO -general HO's policy was to allow aliens enter UK for study, Cs studied scientology which HS then deemed harmful & refused their app to stay; held: no right to extension or fair hearing - no breach of fair procedure. Denning: whether admin body is bound to give person affected opportunity to make reps depends on whether he's got some right, interest or LE of which he wouldn't be fair to deprive him w/out a hearing. o US Tobacco International  - company making oral snuff challenged the ban successfully b/c during consultation required by statute wasn't given grounds for it (required before Min. could introduce new regime) o R v Devon, ex p Baker - LA considering closing of residential home didn't have a duty to notify &
consult each resident who might be affected but had duty to act fairly & give sufficiently prominent notice +
allow opportunity to make reps, give objections & consider them.
Decision as to whether it's OK to resile will be largely fact sensitive - assessment to determine if there are overriding reasons to justify the departure. Substantive Protection of LE - C seeks particular benefit or commodity (e.g. welfare benefit, licence) & claim is founded on government's action said to justify the existence of LE Pre-Coughlan Law
Unclear if SLE existed in UK law, especially where general policy relied on by C was replaced with different policy choice o Hamble Fisheries - HF bought 2 fishing vessels w/purpose of transferring licences to larger one, Min. then changed policy, C argued breach of LE b/c of intro of severe measures with immediate effect + expenditure in reliance. Sedley LJ: policy/practice created LE protected by admin law. Test to review legality of policy changed isn't irrationality - court will intervene where new policy decision was irrational - court will intervene if expectation has legitimacy which out-tops the policy choice.
Court could intervene only where new policy decision was irrational, perverse or Wednesbury unreasonable o Hargreaves  - HS changed policy on prisoners' home leave w/immediate effect in light of crime concerns. Held it would have severely traumatising effect on some prisoners but HO acted lawfully. Approach in Hamble Fisheries was 'heresy' & 'wrong in principle'.
SLE may exist where gen. policy/practice was departed from in circs of particular case o Khan; R v SS for Transport, ex parte Richmond  - in acc with statutory policy Min. announced new regulations on overnight flying, applicable to certain planes, failing to comply w/statute requiring specification of some factors. Laws LJ: a) Procedural protection - PBs by express undertaking/past practice/combination has represented it will give C right to be head before making the change in policy = LE of being consulted ? courts will enforce unless other considerations, e.g. national security, prevails
