The Law Lords have given the go-ahead for the deportation from the UK of the radical cleric Abu Qatada.
Five Lords unanimously threw out his appeal against returning to Jordan, where he faces jail for terrorism.
Qatada had alleged that his conviction in Jordan was based on evidence extracted by torture.
The 48-year-old cleric is one of Europe's most influential extremists and is currently in Belmarsh high security prison.
This key decision by the Law Lords means Home Secretary Jacqui Smith can begin deportation proceedings - but in practice his final removal may wait until after the European Court of Human Rights hears his case.
The five Lords also unanimously supported the deportation of two Algerian terrorism suspects whose cases covered similar grounds.
