The National Defense Authorization Act (NDAA), signed by President Barack Obama December 31, 2011, codifies into law the post-9/11 practice of indefinite detention without charge of terrorist suspects. Martin Scheinin, professor of international law and former UN Special Rapporteur on human rights and counter-terrorism from 2005 to 2011, offered his thoughts on the new law and its potential implications for the global counter-terrorism struggle.

Casey L. Coombs: First, Mr. Scheinin, could you provide your general impressions of the NDAA’s indefinite detention provisions vis-à-vis international legal standards governing civil liberties?

Martin Scheinin: The NDAA builds upon the well-established rule in international humanitarian law (law of armed conflict) that during an international armed conflict combatants, i.e. soldiers of one of the states involved in the war, can be detained as prisoners of war until the end of hostilities. When there is an international armed conflict and when someone is a combatant, then such detention does not amount to arbitrary detention that would violate international human rights law. The NDAA extends the possibility - even presumption - of indefinite detention to terrorism, far beyond genuine situations of international or even non-international armed conflict. And it extends indefinite detention to persons who are not combatants, or analogously situated persons in a non-international armed conflict. For instance, persons who are held to have provided substantial support to terrorism would be subject to indefinite detention. This approach has no support in the laws of war and will unavoidably result in what human rights law considers arbitrary detention and hence a violation of international treaties legally binding upon the United States, such as the International Covenant on Civil and Political Rights.

CLC: As a world leader and active promoter of universal human rights, the practice of indefinite detention without charge would seem to clash with U.S. ideals. Could you comment on this contradiction?

MS: One of the main lessons learned in the international fight against terrorism is that counter-terrorism professionals have gradually come to learn and admit that human rights violations are not an acceptable shortcut in an effective fight against terrorism. Such measures tend to backfire in multiple ways. They result in legal problems by hampering prosecution, trial and punishment. The use of torture is a clear example here. They also tend to alienate the communities with which authorities should be working in order to detect and prevent terrorism. And they add to causes of terrorism, both by perpetuating "root causes" that involve the alienation of communities and by providing "triggering causes" through which bitter individuals make the morally inexcusable decision to turn to methods of terrorism. The NDAA is just one more step in the wrong direction, by aggravating the counterproductive effects of human rights violating measures put in place in the name of countering terrorism.
