In the case of Soering v. The United Kingdom, the European Court of Human Rights ruled that the United Kingdom was not permitted under its treaty obligations to extradite an individual to the United States, because the United States' federal government was constitutionally unable to offer binding assurances that the death penalty would not be sought in Virginia courts. Ultimately, the Commonwealth of Virginia itself had to offer assurances to the federal government, which passed those assurances on to the United Kingdom, which extradited the individual to the United States.
