On October 1, 2010, the Constitutional Court of Ukraine overturned the 2004 amendments, considering them unconstitutional.[9][10] The Court had started to consider the case on the political reform in 2004 under a motion from 252 coalition lawmakers regarding the constitutionality of this reform of July 14, 2010.[11][12][13] The 2010 nullification decision was highly controversial. The Council of Europe's Human Rights Commissioner received several reports alleging that the resignation of four judges in the run-up to the decision occurred as a result of extensive pressure by the executive.[14] On November 18, 2010 The Venice Commission published its report titled The Opinion of the Constitutional Situation in Ukraine in Review of the Judgement of Ukraine's Constitutional Court, in which it stated "It also considers highly unusual that far-reaching constitutional amendments, including the change of the political system of the country - from a parliamentary system to a parliamentary presidential one - are declared unconstitutional by a decision of the Constitutional Court after a period of 6 years. ... As Constitutional Courts are bound by the Constitution and do not stand above it, such decisions raise important questions of democratic legitimacy and the rule of law".[15]
On February 21, 2014 the parliament passed a law that reinstated the December 8, 2004 amendments of the constitution.[16] This was passed under simplified procedure without any decision of the relevant committee and was passed in the first and the second reading in one voting by 386 deputies.[16] The law was approved by 140 MPs of the Party of Regions, 89 MPs of Batkivshchyna, 40 MPs of UDAR, 32 of the Communist Party, and 50 independent lawmakers.[16] According to Radio Free Europe, however, the measure was not signed by the then-President Viktor Yanukovych, who allegedly was subsequently removed from office without the constitutionally required procedures.[17]
