"6. (a) In determining whether there was a material difference between Mrs Chowns' case and that of the male comparator the Industrial Tribunal wrongly required the Appellant to objectively justify the grounds for the difference in pay. The learned Chairman relied wrongly upon the case of Rainey v Greater Glasgow Health Board[1987] IRLR 26 . The proper approach to this issue is set out in the case of Tyldesley v TMC Plastics[1996] IRLR 395 ."
"In considering this defence raised by Farnborough College of Technology the tribunal directed itself, applying the authority of Rainey v Greater Glasgow Health Board[1987] IRLR 26 , that unders. 1(3) of the Equal Pay Act 1970 the onus lies upon the employer to demonstrate objectively justified grounds for the difference in pay between the woman and the man."
"Even if the Tribunal had been correct in holding that the Industrial Tribunal's reasons were not sufficiently clear this would not have entitled it to arrogate to itself the full functions of an Industrial Tribunal and so reach its own decision. The Appeal Tribunal can correct errors of law and substitute its own decision insofar as the Industrial Tribunal must, but for the error of law, have reached such a decision. But, if it is an open question how the Industrial Tribunal would have decided the matter if it had directed itself correctly the Appeal Tribunal can only remit the case for further consideration."
"It is with regard to this aspect that there are divergent views between the chairman and the members of the tribunal. The majority view of the members is that they reject the explanation given by Farnborough College of Technology for the difference in pay. They are not satisfied that Farnborough College of Technology casts its net sufficiently wide when recruiting engineering lecturers properly to justify the difference in pay on the ground contended.
