the court session. Thus, the judges did not have time to study the 84-page case log. The manner of the process proved that the decision to alter the board of judges was made beforehand. At the very end, Tymoshenko's defense boycotted the court session. On 23 December 2011, the Kyiv Court of Appeal issued a ruling which fully supported the verdict of the Pechersk court. The judges didn't find any violations during the pre-trial investigation or trial on the "gas case", overruling the claims of Tymoshenko's defense. Cassation On 26 January 2012, Tymoshenko's defense submitted a cassation appeal to the High Specialized Court for Civil and Criminal Cases regarding the "gas case" verdict. On 16 August 2012, after a 7-month delay that impeded filing the case to the European Court of Human Rights, the panel of judges of the aforementioned court began hearing the case. The panel finished hearing the case on 21 August and went to the jury room to make decision. The ruling of the Court, issued on 29 August 2012, stated that the appeal of former prime minister Yulia Tymoshenko's defense on the "gas case" should not be satisfied. Media, diplomats, members of parliament and members of an EU special monitoring mission, Pat Cox and Aleksander Kwaśniewski, attended the court sessions. The ruling was announced on the day following public hearing of "Tymoshenko vs Ukraine" (regarding unlawful arrest of ex-prime minister and holding her in custody) case at the European Court of Human Rights. The European Union, PACE, and governments of the United States, Great Britain and Canada expressed frustration with the cassation ruling. "We are deeply disappointed with the consequences of the current situation, when two important opposition leaders cannot stand in the upcoming parliamentary elections, [and] when the court disrespects international standards for fair and transparent processes", a representative of the European Commission, Michael Mann, said in Brussels on 29 August 2012. International reactions The "gas case" trial was viewed by many European and American organizations as a politically charged persecution that violates the law. The European Union and multiple international organizations see the conviction as "justice being applied selectively under political motivation." In June 2012, the European Parliament established a special monitoring mission to Ukraine, conducted by former European Parliament President Pat Cox and former Polish President Aleksander Kwaśniewski. Both politicians observed trials, repeatedly visited Tymoshenko in custody and conducted meetings with Ukraine's authorities
