History. 4 of 6: the 2004, 2007, 2010 (Ahmed) and 2015 rulings came 73 to 127 days after the hearing; the 1984 and 2010 (AP) rulings came within 47 days. The 2001 ruling has no exact hearing date.
Hunch. The last Wednesday for rulings this term is 16 December, so a ruling after 45 days, as in 1984, would now come too late.
The timing market resolves on the Supreme Court's page for this appeal and its future judgments page: YES if the court gives no ruling by the end of 21 December 2026, and NO if it gives its ruling on or before that day, whatever it decides. BBC News and The Guardian settle it if the court's pages cannot be read.
We looked for cases where the UK’s top court reviewed a security decision by a minister against a named group or person, after a first court found it unlawful and the Court of Appeal disagreed. We found seven such appeals since 1984. None was about banning a group.
