The Supreme Court is siding with Guantanamo Bay detainees over the Bush administration.
The high court has ruled that President Bush overstepped his authority in creating military war crimes trials for hundreds of Guantanamo inmates.
In a defeat for both the administration and for some of the president's aggressive anti-terror policies, Justice John Paul Stevens wrote the opinion which says the proposed tribunals are illegal under U-S law and the Geneva conventions.
Two years ago, the court rejected Bush's claim to the authority to detain terrorism suspects and indefinitely deny them access to courts or lawyers.
This case focused on a Yemeni inmate who worked as a driver for Osama bin Laden. He's spent four years at Guantanamo, facing a single count of conspiring against U-S citizens.
A lawyer at an advocacy group calls today's Supreme Court decision "a nail in the coffin" for the Bush administration's plan for military tribunals of terror suspects.
Reacting to the ruling, President Bush is suggesting he'll seek the approval of Congress in order to try terror suspects before military tribunals.
