On October 15, 2019, a Grand Chamber of the Court of Justice of the European Union (CJEU) issued its judgment in case C-128/18 Dumitru-Tudor Dorobantu, a case concerning the interpretation of Article 4 of the Charter of Fundamental Rights of the European Union and Council Framework Decision 2002/584/JHA of June 13, 2002, on the European arrest warrant and the surrender procedures between Member States, as amended by Council Framework Decision 2009/299/JHA of February 26, 2009. Article 4 of the Charter provides for the prohibition of torture and inhuman or degrading treatment or punishment and, under Article. Article 4 of the Charter is to have the same meaning and scope as Article 3 of the European Convention on Human Rights. The case involved the issuance of an arrest warrant for Mr. Dorobantu by a Romanian judicial authority to German authorities, as Mr. Dorobantu resided in Hamburg. Prior to executing the warrant, the German court referred a number of questions to the CJEU for a preliminary ruling concerning material conditions of detention and how to assess whether such conditions comply with EU fundamental rights guarantees. The CJEU ruled effectively that requested judicial authorities must suspend execution of an arrest warrant until they have been provided with sufficient evidence to demonstrate whether or not the fundamental rights of the person in question are in actual danger of being infringed.

On August 8, 2019, the United States Court of Appeals for the Ninth Circuit issued an opinion in Bakalian v. Central Bank of Republic of Turkey, Case No. 13-55664. In this case, the Ninth Circuit affirmed the district court's dismissal of plaintiffs’ claims seeking compensation from the Republic of Turkey and two Turkish national banks for lands that they claim were unlawfully confiscated from their ancestors during what the Court refers to as the Armenian Genocide of 1915–1923. In 2006, California adopted a statute extending the statute of limitations for claims arising out of the Armenian Genocide to December 31, 2016. Thus, the claims filed by the plaintiffs in 2010 were not time-barred under the statute; however, the panel found that since the Court had previously found the statute to be unconstitutional, no statute existed to extend the statute of limitations and therefore the claims were time-barred. The panel held that since the claims were plainly time-barred, the Court need not address legal questions posed regarding Foreign Sovereign Immunities Act jurisdiction.
