All members of the Council of Europe (which includes nearly all European countries and every member of the European Union) have adopted the European Convention on Human Rights. The optional Protocol No. 7 to the convention, Article 4, protects against double jeopardy: "No one shall be liable to be tried or punished again in criminal proceedings under the jurisdiction of the same State for an offence for which he or she has already been finally acquitted or convicted in accordance with the law and penal procedure of that State."
