Justices consider rights of detainees Consular access cases are heard By Charles Lane, Washington Post | March 30, 2006 WASHINGTON -- On a December night in 1997, a Honduran man swung a baseball bat and killed James Merry outside a Popeye's restaurant in Springfield, Va. Mario Bustillo was convicted of murder and sentenced to 30 years. That local slaying has evolved into a Supreme Court case with major implications for the rights of 21.1 million noncitizens in the United States, as well as for US international relations. At issue is the Vienna Convention on consular access, an agreement among the United States and 160 other nations that guarantees foreign detainees access to diplomats from their home country. In oral arguments at the court yesterday, a lawyer for Bustillo told the justices that his conviction should be overturned because Virginia authorities never informed him of his Vienna Convention rights. As a result of the delay, Mark Stancil said, Bustillo, who maintains another man from his home country is the real killer, was denied ''critical exculpatory evidence in the possession of the Honduran government." The Vienna Convention issue has generated several difficult cases for the court in recent years, and the Bustillo case offers the justices a chance to clarify the domestic effect of treaties, which the Constitution says are part of ''the supreme law of the land." A ruling in Bustillo's favor could affect relations between millions of noncitizens and local law enforcement, whose knowledge of and compliance with the Vienna Convention is spotty. It would be a defeat for the Bush administration, which says the convention should be enforced through diplomatic negotiations. But it would represent a major step toward incorporating international law into US domestic affairs -- as several justices have been urging in recent years. In a companion case, a lawyer for Moises Sanchez-Llamas, a Mexican convicted of trying to kill a police officer in Oregon, said his client's statements to police should not have been admitted as evidence because they were obtained without notifying him of his Vienna Convention rights. None of the justices seemed eager to embrace that claim, but they appeared more evenly divided on the two men's basic contention that the Vienna Convention creates individual rights that can be enforced by lawsuits in a US court. Ratified by the United States in 1969, the convention commits signatories to provide one another's citizens access to consular officials if they are arrested and to inform detainees of these ''rights" ''without delay." The two cases argued yesterday raise the issue of whether the international court's interpretation of the Vienna Convention should essentially be binding on all 50 states. Backed both by the Bush administration and by 28 other states, Virginia and Oregon counter that neither the treaty nor the international court's ruling can trump the states' own rules of criminal procedure. To decide that noncitizens can belatedly raise Vienna Convention claims, they argue, would give noncitizens a right that Americans do not have with regard to claims under the Constitution, and that is denied to Americans by governments abroad. The cases are Bustillo v. Johnson and Sanchez-Llamas v. Oregon. A decision is expected by July.
