“In relation to the final point, the First-tier Tribunal (F-tT) have the jurisdiction to obtain evidence relating to the claimant’s previous award of benefit, whether that is employment and support allowance (ESA) or DLA. However, the F-tT are only expected to request this information if they find that the information contained within the ESA or DLA claim is relevant AP v Secretary of State for Work and Pensions (PIP)[2016] UKUT 416 (AAC) CPIP/1042/2016 5 to the claimant’s award to PIP. The same principle would apply to the Secretary of State, but is by no means mandatory given that both ESA and DLA are two different benefits with two different sets of criteria to be satisfied for an award to be made.”
