"…It is clear that it was not an illegal contract, nor tainted with illegality. The fact is that the Claimant at the onset of the engagement made a choice that he would prefer to be treated as self employed. Arguments could be raised in support of self employment status or employment status and generally the matter is never cut and dried but must depend upon various characteristics and background details. Indeed the Inland Revenue said that it was a finely balanced matter (D28). In the Tribunal's view, just because a document had been prepared by the Respondent (D23-24) and signed by the Claimant purporting to support the case for self employment, does not render the contract illegal. The dividing line between self employment and employment status can often be blurred and in the Tribunal's experience it is a regular occurrence that the Inland Revenue will scrutinise arrangements of purported self employment status to see whether it falls on that line or on the line of employment status. In the event, facts generated by the Respondent and signed by the Claimant were put before the Revenue arguing that the reality was self-employment. The Tribunal finds that there is nothing inherently illegal regarding the contract. The parties were arguing that the factual situation should be interpreted as one of self-employment as opposed to employment status. Furthermore, the parties were complying with Inland revenue guidelines at the time that if somebody is self-employed, tax would be deducted at source at 18% and there was a CIS certificate in place. In the Tribunal's view the Respondent in pursuing this rather vestigial argument of illegality were motivated by the unfairness, as they see it, of the Claimant having his cake and eating it, by urging upon the Respondents at the inception of his arrangement a self employed position and then when the engagement ceased and it suited him, to change his stance to maintaining he was an employee. The situation in the Tribunal's view comes nowhere near the circumstances where the contract could be determined to be illegal."
"The objection, that a contract is immoral or illegal as between plaintiff and defendant, sounds at all times very ill in the mouth of the defendant. It is not for his sake, however, that the objection is ever allowed; but it is founded in general principles of policy, which the defendant has the advantage of, contrary to the real justice, as between him and the plaintiff, by accident, if I may so say. The principle of public policy is this; ex dolo malo non oritur actio. No court will lend its aid to a man who founds his cause of action upon an immoral or an illegal act. If, from the plaintiff's own stating or otherwise, the cause of action appears to arise ex turpi causa, or the transgression of a positive law of this country, there the court says he has no right to be assisted. It is upon that ground the court goes; not for the sake of the defendant, but because they will not lend their aid to such a plaintiff. So if the plaintiff and defendant were to change sides, and the defendant was to bring his action against the plaintiff, the latter would then have the advantage of it; for where both are equally in fault, potior est conditio defendentis. The question therefore is, whether, in this case, the plaintiff's demand is founded upon the ground of any immoral act or contract, or upon the ground of his being guilty of any thing which is prohibited by a positive law of this country." (2) As Lord Mansfield made clear, the doctrine is rooted in public policy. As such it can work harshly on the parties in particular cases, as Lord Goff noted in Tinsley v Milligan [1994]1A.C.340, "tbe principle is not a principle of justice; it is a principle of policy whose application is indiscriminate and so can lead to unfair consequences as between the parties to litigation. Moreover, the principle allows no room for the exercise of any discretion by the court in favour of one party or the other." (3) There are three categories of case where a contract may be tainted with illegality. These were identified by Lord Justice Peter Gibson in his seminal judgment in Hall v Woolston Leisure Services Ltd[2000] IRLR 578 (paras 30-31). The first is where the contract is entered into with the intention of committing an illegal act. The second is where the contract is expressly or impliedly prohibited by statute. The third- and the category relevant to these two appeals- is where the contract was lawful when made but has been illegally performed, and the party seeking the assistance of the court knowingly participated in the illegal performance. (4) In order to fall within this third category, it is traditionally said that there are two requirements. There must be knowledge of the illegal performance and participation: see the observations of Gibson LJ in the Hall case, para 31, referring to passages from the judgments of Lord Denning MR and Scarman LJ, as he then was, in Ashmore Benson Ltd v Dawson Ltd .[1973] 1 WLR 828 . (5) Implicit in the analysis of Gibson LJ is of course a third requirement, namely that the performance must be illegal. It must be a form of illegality which properly attracts the operation of the doctrine. (6) The concept of knowledge requires that the employee must have knowledge of the facts which renders the performance illegal: Gibson LJ in Hall para 38. However, it is irrelevant whether the party appreciates that what he is doing is illegal. Ignorance of the law is no excuse. This has been reiterated on many occasions: see e.g. Miller v Karlinski(1945) 62 TLR 85 (CA); Salvesen v Simons[1994] IRLR 52 . (7) The concept of participation on requires some active participation. There are cases in which the courts have held that mere knowledge of the illegality coupled with a failure to do anything about it can constitute participation: see e.g. Newland v Willer (Hairdressers) Ltd .[1981] IRLR 359 where an employee who became aware that her employers were deceiving the Revenue was held to be a participant in the scheme and therefore unable to claim unfair dismissal. However, in the Hall case the facts were similar. Mrs Hall asked to receive her pay gross but it came to her attention that her employers were deceiving the Revenue and not paying the appropriate tax. The Court of Appeal held that the Employment Tribunal was wrong to find that this was sufficient to render the contract an illegal one. There was no illegality by Mrs Hall. Peter Gibson LJ said this (para 47): "
"What therefore Salvesen decides is that where an employee has made a positive choice to operate arrangements which have the effect of depriving the Revenue of payment to which it is entitled, contracts giving effect to those arrangements will be unenforceable notwithstanding that the employee may genuinely have believed them to be lawful. The position might be different where the initiative came from the employer; but those are not the facts in that case. "
"It is suggested, again by Mr Clifford, that it would be contrary to public policy to allow him to resile from his agreement. That, of course, was the basis of the dissenting judgment of Lord Justice Lawton in the Ferguson[1976] IRLR 346 case and, as it was the dissenting judgment, I need not, respectfully, refer to it again, save only to say this. Public policy is a dangerous argument to mount in this type of case where it just happens that the merits are on the side of the appellant. As the majority judgment of the Employment Appeal Tribunal pointed out: '… individual labelling of the relationship would strike at the root of the protection afforded to an employed person by the Employment Protection legislation.' It would not only strike at that protection, but also at the protection afforded by other acts such as the Factory Acts and other analogous legislation."
"…the failure to warn and consult was so fundamental that it makes it impossible to say that the failure made no difference or that we can sensibly reconstruct the world as it might have been."
"…The matter will be one of impression and judgment so that a tribunal will have to decide whether the unfair departure from what should have happened was a kind which makes it possible to say, with more or less confidence, that the failure made no difference, or whether the failure was such that one cannot sensibly reconstruct the world as it might have been."
