听力原文： A delegation of American officials appeared before an international legal panel on Friday to argue that in its fight against terrorism, the United States had not violated its treaty obligations

The delegation's report to the United Nations panel, which was meeting in Geneva, did not break new ground. The officials contended that despite instances of abuse in Afghanistan, Iraq and Guantánamo Bay, Cuba, the United States has not systematically mistreated prisoners and remained committed to a global ban on torture.

Under the Convention Against Torture, a 1987 treaty that is a centerpiece of international human rights law, the United States was supposed to have reported to the United Nations panel on its compliance by 1999.

The panel, known as the Committee Against Torture, will review the American report and issue findings later this month, but it has no power to enforce its conclusions.

The delegation included more than two dozen representatives from the State, Defense, Justice and Homeland Security Departments, but not from the C.L.A.
