In East of England Ambulance Service NHS Trust v Sanders the EAT has held that a tribunal committed a procedural error in searching on the internet for evidence that supported a claimant’s case that she was disabled, and in relying on that evidence in its conclusions. The tribunal thereby gave the impression of bias against the respondent employer. The EAT also commented on a procedural issue in the appeal, warning parties that they are obliged, when preparing a bundle of authorities, to mark the passages that are to be relied upon.
