“1. I have decided that Mr [E] has a realistic prospect of persuading the Upper Tribunal that the First-tier Tribunal erred in law. 2. The Tribunal found that, when Mr [E] was first awarded pension credit, he was instructed to notify those changes listed in the IN4 booklet. However, a piece of the jigsaw seems to be missing. The instruction was spread across two documents, the leaflet itself and the award letter which accompanied it (see p.4 of the specimen IN4 in the papers). The award letter contained the telephone number to which changes were to be notified or, if notified in writing, the relevant postal address. 3…there is a feature of this case that raises the question whether it was fair for the First-tier Tribunal to proceed without having had sight of the award letter and the telephone number which it displayed. 4. Mr [E] says he made disclosures to Jobcentre Plus and the Tribunal seems to have accepted that. In the early part of 2005, his Jobcentre Plus letters gave 0845 6002773 as his contact number. Then on30th November 2005 , he received a letter on Pension Service headed note-paper (p.120). This includes the very same contact number – 0845 6002773. 5. That these numbers match raises the possibility that the telephone number in the Pension Credit award letter was the same number as that previously displayed on Mr [E’s] Jobcentre Plus letters. The specimen letter at p.46 does not assist; it contains no telephone number. Hence, Mr [E], in making disclosure to what he thought was Jobcentre Plus, might in fact have made a disclosure in accordance with the instructions in the IN4 booklet. Arguably, the First-tier Tribunal, being an inquisitorial tribunal, erred in law by failing to investigate that possibility. I grant permission to appeal on that ground.”
