The supermarket giant argued that 700 claims submitted to the employment tribunal eight years ago should have been struck out because they did not include the correct reference number from a certificate issued by the Advisory, Conciliation and Arbitration Service (ACAS) showing they had completed the early conciliation process.
Delivering judgment this month in Sainsbury's Supermarkets Ltd v Clark and others [2023] EWCA Civ 386, however, Lord Justice Bean said: ‘These are highly technical applications lacking any substantive merit.
‘When industrial tribunals were established more than half a century ago the purpose of Parliament was to create a speedy and informal system free from technicalities. It has been repeatedly stated that employment tribunals should do their best not to place artificial barriers in the way of genuine claims.
‘It should be emphasised that there is no suggestion that any of these claimants failed to make the necessary reference to ACAS before the claim was issued, nor that any of them failed to obtain a certificate by ACAS demonstrating that such a reference had been made. The complaint is no more and no less than that the employment tribunal claim form did not give the appropriate certificate number.’
Leigh Day partners Linda Wong and Lauren Lougheed, representing the workers, said: ‘Women are still being paid less than men more than 60 years after the introduction of equal pay laws.
‘Sainsbury’s had a choice about defending these claims on their merits, or trying to reduce the number of claimants by making “highly technical applications”.’
The claims, which could result in tens of thousands of pounds in back pay being awarded if successful, will now move to an employment tribunal hearing scheduled for March 2024.
