The upper tribunal has found it was wrong for the DWP to refuse claimants the right to appeal if they took more than a month to ask for a review of the benefit decision.

It comes just a week after a  supreme court finding that the government was unlawfully charging fees of up to £1,200 for access to employment tribunals.

The DWP system was challenged by the Child Poverty Action Group and two claimants with serious mental health problems who were refused disability benefits and then failed to ask for an internal review within the one-month time limit.
