Immigration – Upper Tribunal (Immigration and Asylum Chamber). The Upper Tribunal (Immigration and Asylum Chamber) had jurisdiction to correct an error in its decision if it was a mere error of expression. However, the Court of Appeal, Civil Division, held that in the particular circumstances of the case, it would not be right for it to exercise that jurisdiction, as it would not be possible to exclude a real perception of unfairness if the UT were simply to produce a corrected version of the decision that faithfully reflected the figures that it had been given by the Secretary of State.
