A group of 10 terror suspects who claim evidence gained through torture resulted in their arrests are to take their case to the House of Lords.
The group will take their case before the Law Lords
Civil liberties groups backing the foreign nationals' appeal say information gained through torture should not be admissible.
Last year the Court of Appeal rejected their case, ruling that the government had acted legally in detaining the men.
The Law Lords will hear evidence between 17 and 20 October this year.
The men were detained under the 2001 Anti-Terrorism and Security Act, which came into force after the 11 September attacks on the US.
The Court of Appeal's decision last August was welcomed by then Home Secretary David Blunkett.
At that hearing, lawyers representing the men challenged a decision by the Special Immigration Appeals Commission (SIAC) that the government was right to hold them.
The lawyers said the arrests were based on information gained through torture at Guantanamo Bay, in Cuba.
But Lord Justice Pill, sitting with two other senior judges, said he found "no error of approach" by SIAC, and said it was not suggested that the appellants had been tortured.
SIAC previously ruled that there was "sound material" backing the view that the men were a risk to national security.
The commission certified the men as being members of, or belonging to, or supporting or assisting, an international terrorist group.
Fourteen civil liberties groups are backing the suspects.
Shami Chakrabarti, director of Liberty, said: "Liberty is confident that the House of Lords will endorse the overwhelming consensus of decent British people who do not wish to see our government complicit in acts of torture anywhere."
