In this chapter of the DIAG Human v. Czech Republic saga, the Supreme Court affirmed the 2017 decision of the Court of Appeal, which in turn had affirmed the 2011 first instance decision recognizing a Czech ad hoc award. While the party seeking enforcement had not revealed to the 2011 court that applications for review arbitration were pending against the award in the Czech Republic, this argument had become moot by 2017, as the applications had been denied in 2014. Hence, enforcement could not be denied on grounds of public policy because of the procedural fraud allegedly committed by the applicant. The Supreme Court also found that it could not review the holding of the Court of Appeal that the award was binding under Czech law, because the interpretation and application of foreign law were questions of fact which pertained to the merits and fell outside the cassation review.
