“In conferring a right of appeal in the terms of section 4(2)(b), Parliament must therefore have intended that it would be open to a person included on a barred list to contend before the Upper Tribunal that the DBS was mistaken to find that they committed the relevant act – or in other words, to contend that they did not commit the relevant act and that the decision of the DBS that they did was therefore mistaken. On its plain words, the section does not require any more granular mistake to be identified than that” (RI v DBS, per Males LJ at [49]). Further Bean LJ rejected the DBS’s argument that the Upper Tribunal was in effect bound to ignore an appellant’s oral evidence unless it contains something entirely new. He said in RI v DBS at [37] that: “where Parliament has created a tribunal with the power to hear oral evidence it entrusts the tribunal with the task of deciding, by reference to all the oral and written evidence in the case, whether a witness is telling the truth.”
