"We find that, far from being a victim of Mr Brinton's [that is a representative of the employers] threatening and overbearing manner and being forced to maintain a status of self-employment for fear of losing his job, we conclude that Mr Soteriou was the prime mover in ensuring that his self-employed status was preserved following the Contributions Agency investigation. Not only that, but he made fraudulent statements to the investigators, knowing full well that the true position would have prejudiced that status. ... Accordingly, we find that it would be against public policy to allow Mr Soteriou to come to this tribunal to try to claim the benefits accorded to employees under the employment rights legislation. He volunteered to exclude himself from the employment protection system from the outset."
"An arrangement between two parties to put forward a dishonest description of their relationship so as to deceive the revenue would clearly be illegal and unenforceable."
"The findings as to illegality in the Employment Tribunal operate as an issue estoppel. Accordingly, the High Court would be bound to find that the contract for breach of which the claimant seeks to sue is unenforceable and the claim would be bound to fail. This is also the case even if this is not a case of issue estoppel, but rather of alleged abuse, for the new matters are matters that could and should reasonably have been adduced before the Employment Tribunal."
"But if he does not have to [rely on his illegal action] ... then in my view the question is whether the method of performance chosen and the degree of participation in that illegal performance is such as to 'turn the contract into an illegal contract' ..."
"It is a question of fact in each case whether there has been a sufficient degree of participation by the employee."
