Article: The Limits of International Law: Efforts to Enforce Rulings of the International Court of Justice in U.S. Death Penality Cases

Since the Supreme Court reinstated the death penalty in 1976,[1] the United States has executed twenty-eight foreign nationals from fifteen different countries.[2]  Most of those foreign nationals were never informed of their rights to consular notification and access under Article 36 of the Vienna Convention on Consular Relations,[3] a treaty the United States ratified in 1969.[4]  Violations of Article 36 in capital cases have caused consternation in foreign capitals and endless litigation in domestic courts and international tribunals.  Mexico, which has the largest number of foreign nationals on death row,[5] established the Mexican Capital Legal Assistance Program in 2000 to assist its nationals facing the death penalty and to ensure that Vienna Convention claims were aggressively litigated.[6]  Several foreign governments have filed briefs in state and federal courts describing the nature of the assistance they could have provided if their nationals had been promptly notified of their consular rights.[7]  In dozens of cases, appellate lawyers have argued that consular assistance could have made the difference between life and death.  Yet, even in the wake of favorable judgments from the Inter-American Commission of Human Rights,[8] the Inter-American Court on Human Rights,[9] and the International Court of Justice (ICJ),[10] national courts have persistently refused to grant any measure of relief to condemned foreign nationals, even in cases in which the violation was undisputed.  As of September 2011, domestic courts have overturned death sentences on the basis of Article 36 violations in only two cases.[11]

In light of these statistics, it is tempting to conclude that Article 36 litigation has had negligible effects on the application of the death penalty in the United States.  And indeed, under no circumstances could even the most optimistic internationalist claim that Article 36 litigation has been a resounding success.  But it would be similarly misguided to say that Article 36 litigation has had no effect on domestic legal culture.  As an initial matter, the United States complied with the ICJ’s provisional measures order in Avena and Other Mexican Nationals,[12] leading to a five-year moratorium on the execution of Mexican nationals in the United States.[13]  In addition, the death sentences of two Mexican nationals were vacated in direct response to the ICJ’s final judgment in Avena; one of those cases is examined in greater detail below.  And finally, litigation over violations of the Vienna Convention in U.S. death penalty cases has attracted substantial public commentary calling on the courts and Congress to comply with their international obligations.  Although it is too soon to say whether the United States will ultimately comply with the ICJ’s Avena judgment in the cases of Mexican nationals who remain on death row, there can be little question that litigation in domestic and international tribunals has led to increased awareness of the United States’ obligations under the Vienna Convention, which in turn has led to greater compliance with Article 36 at the trial level.
