Court name: Court of Appeal
Date of decision:

The applicant applied for British citizenship on the basis of s.4B of the British Nationality Act 1981 (which does not allow the grant of British citizenship when the applicant already has another nationality), relying on a letter from a Pakistani Consulate confirming that his Pakistani nationality was cancelled. The Court of Appeal reversed the lower court’s decision, which had been in favour of the applicant, on the basis that (1) it failed to apply the principle that the person's nationality was to be determined by reference to the actual law of the state on the basis of expert evidence, not what agencies of the state might assert about that person's nationality; and (2) the lower court’s reading of Pakistani law was mistaken.
