WASHINGTON -- A federal appeals courts decision to toss the conviction of Osama bin Ladens former driver could have implications for future prosecutions of terrorism suspects.
The driver, Salim Ahmed Hamdan, was detained by U.S. troops in Afghanistan in November 2001 and sent to Guantánamo. In the first U.S. military war crimes trial since World War II, a jury of six military officers found Hamdan guilty in 2008 of providing material support to terrorism and sentenced him to 5 1/2 years in prison.
But the U.S. Court of Appeals for the District of Columbia on Tuesday threw out that conviction, stating in a 3-0 decision that material support for terrorism was not proscribed as an international war crime until Congress passed the Military Commissions Act in 2006. Since Hamdan worked for bin Laden from 1996 to 2001, he cannot be punished retroactively, the court concluded.
Indeed the Executive Branch acknowledges that the international law of war did not and still does not identify material support for terrorism as a war crime, wrote Judge Brett Kavanaugh.
If the government wanted to charge Hamdan with aiding and abetting terrorism or some other war crime that was sufficiently rooted in the international law of war at the time of Hamdans conduct, it should have done so, Kavanaugh wrote.
Hamdans legal vindication is the latest challenge to the controversial war courts set up by President George W. Bushs administration after the terrorist attacks of Sept. 11, 2001. The Yemeni driver also was at the center of a landmark 2006 Supreme Court case that struck down the war courts as unconstitutional, forcing the Bush administration to revise the system and try again.
Tuesdays decision dealt another blow to the war courts by upending material support for terrorism as an offense triable by military commission.
Hamdans attorney, Joe McMillan, a lawyer with Seattle-based Perkins Coie, said he regards the ruling as a victory for the American justice system.
We see it as an important statement that the U.S. must conform to the rule of law as it goes forward, even in times of perceived national emergency, McMillan said.
Although the ruling will help clear his clients name, its probably more important to the American legal tradition than to Hamdan, he said. Its long been deemed unjust to hold a person criminally liable for conduct that was not recognized as criminal at the time it occurred, he said.
The decision is likely to be reviewed by the Supreme Court, even though the nations highest court has been reluctant to review Guantánamo detainee cases in recent years, said Eugene R. Fidell, who teaches military justice at Yale Law School.
Above all, the decision shows how important it is to have civilian courts review decisions of the military commission and the Court of Military Commission Review, Fidell said. The fact that the decision overturns a commission case demonstrates that the regular federal courts can be a bulwark against government overreaching.
The decision also is significant in its rejection of Congress claim that material support for terrorism was an offense under the law of nations even before the Military Commissions Act of 2006, he said.
If and when the Supreme Court considers the case, we will know more about the interplay between the legislative and judicial branches in determining what is and what is not forbidden by the law of nations, Fidell said.
