Question to the Department for Work and Pensions:

To ask the Secretary of State for Work and Pensions, for what reasons 60 per cent of appeals made in personal independence payment cases have resulted in the initial decision being overturned.

The Department gathers information on the reasons why PIP decisions have been overturned from its Presenting Officers and the summary reasons it gets back from the Tribunal hearing. Internal Management Information for 2015/16 indicates that either new oral or documentary evidence supplied at the hearing are the leading reasons for PIP decisions being overturned in 75% of overturns recorded.

These figures are from internal DWP systems, where only one of possible multiple reasons can be recorded, and are derived from unpublished information and have not been quality assured to National Statistics or Official Statistics standard.
