Could you provide a link to that please?
All I can find is the Lloyds Bank case and the argument over Guarantee Minimum Pensions.

1990 – in the *Barber case (17 May 1990), the European Court ruled that ^occupational pensions were deferred pay and, as such, schemes were required to treat men and women equally. As a result, schemes “equalised” their retirement ages, often at age 65, and adjusted their benefits accordingly.^
^However, as GMPs were designed to integrate with the then state pension, and the rules governing them are set out under legislation, there was some doubt as to whether Barber applied.^
This wasn’t taken up by then pensions minister Angela Eagle until 2010. It wasn’t until 2018 that the High Court ruled that GMPs must be equalised.
*The Barber case was about a man.
Barber was an employee of Guardian Royal Exchange and a member of its pension scheme. The scheme was non-contributory, with a normal pensionable age of 62 years for men and 57 years for women. If an employee was made redundant s/he would be entitled to an immediate pension income at the age of 55 years if a man and 50 years if a woman.
Barber was made redundant at the age of 52 years, and did not receive his pension. If he had been a woman he would clearly have been entitled to an immediate pension. He took a claim that the pension rules were sex discrimination and a breach of article 119 of the Treaty of Rome, relating to equal pay for equal work. This was referred to the European Court of Justice.
