‘26C Remedies and defences (1) Proceedings in respect of an actionable threat may be brought against the person who made the threat for— (a) a declaration that the threat is unjustified; (b) an injunction against the continuance of the threat; (c) damages in respect of any loss sustained by the aggrieved person by reason of the threat.’
‘[34] Since Blake I see no reason why, if the beneficiary of a restrictive covenant is unaware of its infringement in time to obtain an injunction immediately, but is able to obtain an injunction for the future after the defendant by the infringement has obtained some benefit, the appellant should be precluded from obtaining an injunction and, if justice requires, a reasonable sum to compensate for the past infringement, even though he may not be able to show any financial loss to himself. … [35] I can take the example put in argument of breach of a restrictive covenant not to use land for a pop concert, committed in circumstances where the beneficiary was out of the country and suffered no discomfort at all. Why should he not obtain an injunction to restrain repetition and a reasonable sum having regard to the financial benefit obtained by the neighbouring landowner from the infringement? Likewise, if a breach of contract occurs in such circumstances that there is no possibility at all of obtaining an injunction (e.g. because the interests of a third party have intervened), I see no reason why that should, since Blake, present any insuperable bar, in appropriate circumstances, to an order for payment of a reasonable sum having regard to any benefit made by the infringement, even though the appellant cannot prove any financial loss (cf. Jaggard [v Sawyer[1995] 1 WLR 269 (CA)], at p.291, per Millett L.J.). Lord Nicholls in Blake took as ‘‘a useful general guide, although not exhaustive’’ of circumstances in which an account of profit might be appropriate, ‘‘whether the plaintiff had a legitimate interest in preventing the defendant’s profit-making activity’’
‘Courts of equity traditionally awarded accounts of profits gained through the infringement of intellectual property or breach of confidence. Relief of this type was seen as a corollary of injunctive relief. As to intellectual property infringements, the remedy has in several cases been put onto a statutory footing.’
‘Apart from intellectual property torts, the account of profits is not an available remedy for common law torts, although damages measured on a licence fee basis are sometimes available, particularly in cases involving proprietary torts and cases of cynical wrongdoing. Since Attorney General v Blake was decided in 2001, the Court of Appeal has confirmed that the account of profits continues to be unavailable in cases involving non-proprietary torts’
‘The defendants contend that this court cannot apply the principle established in Blake’s case to a purely personal tortious claim, and in particular that this court is precluded by precedent, namely the decisions of this court in Stoke-on-Trent City Council v W & J Wass Ltd[1988] 1 WLR 1406 and Halifax Building Society v Thomas[1996] Ch 217 , from holding otherwise. The defendants accept that a restitutionary award could be made for a proprietary tort. (By a “proprietary tort” I mean a tort for which a claimant entitled to property or a property right is entitled to sue for interference on the basis discussed by Lord Nicholls of Birkenhead in Blake’s case. … )’
‘[4] My essential conclusion on the Blake issue is this. The overall holding in Blake’s case is that the law on remedies for interference with property, damages in lieu of an injunction, damages for breach of fiduciary duty and breach of contract should be coherent and that the same remedies should be available in the same circumstances, even if the cause of action is different. On that basis, a restitutionary award is available in tort unless it is precluded by the Wass case[1988] 1 WLR 1406 or the Halifax case[1996] Ch 217 . In my judgment, it is precluded by the Wass case. However, if I am wrong in that conclusion, it is a condition of a restitutionary award that exceptional circumstances of the kind described in Blake’s case[2001] AC 268 should be shown.’
‘[156] … Stoke-on-Trent City Council v W & J Wass Ltd[1988] 1 WLR 1406 is binding on us. I agree with what Arden LJ says, at para 57, that Attorney General v Blake[2001] 1 AC 268 suggests that an account of profits could be ordered for non-proprietary torts. But for the reasons she gives in para 75 I do not think it can be said that the Wass case, which was not cited in Blake’s case, has necessarily been overruled by it. It can stand with Blake’s case. Non-proprietary torts do still therefore fall to be considered as an exception to the general principles articulated by Lord Nicholls of Birkenhead in Blake’s case unless and until the Wass case is overruled.’
