AP, from the New York Times:
Justice Clarence Thomas wrote a strongly worded dissent, saying the court’s decision would “sorely hamper the president’s ability to confront and defeat a new and deadly enemy.”
The court’s willingness, Thomas said, “to second-guess the determination of the political branches that these conspirators must be brought to justice is both unprecedented and dangerous.”
Justices Antonin Scalia and Samuel Alito also filed dissents.
In his own opinion, Justice Stephen Breyer said, “Congress has not issued the executive a ‘blank check.”‘
“Indeed, Congress has denied the president the legislative authority to create military commissions of the kind at issue here. Nothing prevents the president from returning to Congress to seek the authority he believes necessary,” Breyer wrote.
