At the start of last year, a parliamentary ombudsman recommended compensation of between £1,000 and £2,950 for each of those affected.
While the Parliamentary and Health Service Ombudsman (PHSO) could recommend compensation, it could not enforce it and the government rejected it.
Ministers said there was no evidence of “direct financial loss” resulting from the government’s decision, and that Labour did not believe that paying a flat rate to all women at a cost of up to £10.5bn would be “fair or proportionate” to taxpayers.
The Women Against State Pension Inequality (Waspi) campaign had called for payments of at least £10,000 each.
It is pursuing a judicial review of the government’s decision not to pay compensation. Campaigners raised money for the legal challenge and a court capped the contribution to the government’s legal fees if they were unsuccessful.
The case was scheduled to go to the High Court in December. The government has now informed the court of its latest decision.
