Lyle Denniston has this summary of pending Supreme Court litigation dealing with the Combatant Status Review Tribunal process.
In brief, the high Court will issue a decision in the next month – in the
Boumediene and Al-Odah cases – which will address the CSRT's. In both, the court will be asked to determine whether Guantanamo detainees are entitled to habeas relief regardless of the Military Commissions Act, which established the CSRT's as an alternative to habeas review and divested federal courts of jurisdiction to hear detainees’ appeals. Shortly thereafter, the court will determine whether to hear Bismullah, a DC Circuit decision entitling detainees’ lawyers access to classified information.
