Regina v Commissioners of Inland Revenue, ex parte Unilever plc: CA 1996

The Revenue had refused to exercise a discretion in favour of the taxpayer in the same form it had granted for over twenty years. The taxpayer complained that this was unfair.
Held: The new approach to late applications, brought in without any warning, was so unfair as to amount to an abuse of power, notwithstanding that the court accepted that the practice was not such as to engage the legitimate expectation doctrine.
The Commissioners are under a common law duty to treat taxpayers fairly, and not to discriminate without justification between taxpayers. It is not always a condition for a legitimate expectation to arise that there should be a clear, unambiguous and unqualified representation by the public authority, the test is whether the public authority has acted so unfairly that its conduct amounts to an abuse of power.
Sir Thomas Bingham MR said: ‘the categories of unfairness are not closed, and precedent should act as a guide not a cage’ and ‘These points cumulatively persuade me that on the unique facts of this case the Revenue’s argument should be rejected. On the history here, I consider that to reject Unilever’s claims in reliance on the time limit, without clear and general advance notice, is so unfair as to amount to an abuse of power’.
Simon Brown LJ said: ”Unfairness amounting to an abuse of power’ as envisaged in Preston and the other Revenue cases is unlawful not because it involves conduct such as would offend some equivalent private law principle, not principally indeed because it breaches a legitimate expectation that some different substantive decision will be taken, but rather because either it is illogical or immoral or both for a public authority to act with conspicuous unfairness and in that sense abuse its power. As Lord Donaldson MR said in R v ITC, ex p TSW: ‘The test in public law is fairness, not an adaptation of the law of contract or estoppel’.’
and ‘on the one hand mere unfairness – conduct which may be characterised as ‘a bit rich’ but nevertheless understandable, and on the other hand a decision so outrageously unfair that it should not be allowed to stand.’
