"The EAT, in unanimously allowing the employers' appeal, reminded itself of the limitations upon its own jurisdiction in the following passage in the judgment delivered by Knox J:
"The Employment Appeal Tribunal can indeed interfere if it is satisfied that the Tribunal (scil. the Industrial Tribunal) has misdirected itself as to the applicable law, or if there is no evidence to support a finding of fact, since the absence of evidence to support a finding of fact has always been regarded as a pure question of law. It can also interfere if the decision is perverse, as has been explained by May LJ in Neale v Hereford & Worcester CC[1986] IRLR 168 ."
"This is a difficult case. However, on balance, we are unanimous in our view that this was an employee/employer relationship which was to some extent disguised as one of self-employment. We are not satisfied on the evidence that this contract was tainted by illegality and that Mr Campbell should be denied his rights to employment protection."
"In our view on the facts nothing is to be deduced from the failure of Mr Campbell or the Respondent to pay tax and national insurance for Mr Campbell.
"However, the agreement as to a performance related bonus and the "invoices" to which we have referred points to a status of employee."
