Charlie was successful in this appeal against the Secretary of State for Work and Pensions. The appeal concerned the meaning of the words ‘severe mental impairment’ and ‘incomplete development of the brain’ under the Social Security and Contributions Act 1992 and associated regulations.

The Upper Tribunal found in favour for appellant on new medical evidence and the correct interpretation of the statute and regulations in light of that evidence. The decision refers to Charlie’s able representation and wise tactical decisions.
