Citizenship – British citizenship. The condition in s 5(1)(b) of the British Nationality Act 1948, requiring registration of a birth at a UK consulate within one year of its occurrence, was inapplicable in cases where citizenship was claimed by descent from a mother, as prior to the s 4C of the British Nationality Act 1981, such registration could only have been registered by mistake or in defiance of the regulations. Accordingly, the Supreme Court dismissed the appellant Advocate General's appeal against the Inner House's decision, although for different reasons.
