2015–present Polish constitutional crisis
In response to the ruling of the European Court of Human Rights in "Xero Flor w Polsce sp. z o.o. v. Poland", which found that the business was denied the right to fair trial because a judge of the Tribunal was appointed illegally, the Constitutional Tribunal declares that it is not a court within the meaning of Article 6 of the European Convention on Human Rights and rules that the ECHR did not have the right to control the validity of appointments of the Tribunal's judges.
