The wife of an Algerian terror suspect detained in August is demanding the Home Office show in court the evidence on which her husband is being held.
Mr G was in London's Belmarsh prison for more than two years
Mr "G", whose identity cannot legally be revealed, is one of 10 suspects whom the government wants to deport.
His wife said if proof Mr G was guilty were given in court she would accept it, but: "You can't keep people locked up in prison just on secret evidence."
The Home Office said it did not comment on individual cases.
But in a statement it added: "Prosecution is, and will remain, the government's preferred way of dealing with terrorists.
"Priority will continue to be given to prosecuting wherever possible, subject to the over-riding need to protect highly sensitive sources and techniques."
Mrs G told the BBC: "If they have the proof, strong proof, to bring him to justice I will accept it, if they bring him and they find him guilty in court I will accept this."
She said murderers and paedophiles were treated better than terrorist suspects.
"They didn't find them doing anything and just because of what, suspicion, they destroy my life, my husband's life and my daughter's life.
"They have declared war on terrorists but for us we feel like they have just declared war on Muslims."
She said she was very concerned about the prospect of her husband being deported to Algeria.
"They will take him and they will torture him like they've done to other people like this, that's why I'm scared."
Mrs G added: "I'm doing everything to let people know what this country, with their human rights are doing, because this is not fair and this is not justice. They just want to deport him."
Home Secretary Charles Clarke last month published the list of behaviour which can lead to deportation or exclusion from the UK.
Under the Human Rights Act, the UK cannot deport anyone to a country where they may face persecution.
But the government has been negotiating with 10 countries, including Algeria, to gain guarantees that any deportees will not be mistreated.
Before his return to jail last month, Mr G had been the only detainee held under the government's anti-terror laws to be kept under virtual house arrest instead of in prison.
He had been freed on bail from Belmarsh prison in April 2004 on mental health grounds, after being held for two years without trial.
Judges at the Special Immigration Appeals Commission (Siac) were told his mental health had deteriorated during his incarceration.
In February 2005, Home Secretary Charles Clarke lost a bid to have him returned to jail after a judge ruled Mr Clarke had not proved "to the necessary standard" that Mr G had breached his bail conditions.
At the time, Mr G's legal team said the Home Office bid to revoke his bail appeared to have been sparked by secret evidence.
