A judge at Britain's High Court has ruled that so-called control orders British authorities have used in efforts to restrict movements of terrorism suspects violate human rights laws.

Judge Jeremy Sullivan called the orders used by Home Secretary Charles Clark to impose such restrictions conspicuously unfair because they were put into effect without an impartial court hearing.

Home office officials say they will appeal the decision. Meanwhile, the rules restricting the movement of the plaintiff, a British citizen known only as M.B., remain in effect.

British authorities introduced the control orders under the Prevention of Terrorism Act last year after courts struck down their previous policies of detaining terrorism suspects without trial.

The home secretary imposed the orders on M.B. to prevent him from leaving the country to fight U.S. and British forces in Iraq.

The orders, among other things, required M.B. to surrender his passport, stay at a designated address and report to police daily.

The Home Office has imposed similar measures on eight other people.
