A suspected international terrorist has been charged with breaching his control order, it has been revealed.
Public safety comes before rights, the government has argued
It is the first time court proceedings have been launched against someone who is subject to a control order.
The man, identified only as LL, appeared at London's Bow Street Magistrates' Court.
The case cannot proceed until control orders, where terror suspects are put under effective house arrest, have been reviewed by the Court of Appeal.
At the start of July, the government accused a High Court judge of "misunderstandings and errors" over his ruling that control orders contravene human rights.
Mr Justice Sullivan ruled in April and again at the start of July that the orders, which impose detention without charge, break European human rights laws.
Home Secretary John Reid is asking the Court of Appeal to overturn the ruling. He said the judge 'misapplied' the European Convention on Human Rights.
Control orders were brought in for cases where there was not enough evidence for a criminal prosecution.
When placed under them, terror suspects can be tagged, confined to their homes and banned from communicating with others.
The appeal centres on one man who was put under house arrest, but not taken to court because of insufficient evidence.
Friday's hearing took place on Bow Street Magistrates' Court's final day in its 267-year existence. The building is set to be turned into a luxury hotel.
