Since May 2010, a series of criminal cases have been opened against Ukrainian politician and former Prime Minister of Ukraine Yulia Tymoshenko. Tymoshenko is one of Ukraine's most important politicians. After Tymoshenko was released from prison on February 22, 2014, in the concluding days of the Euromaidan revolution, following a revision of the Ukrainian criminal code that effectively decriminalized the actions for which she was imprisoned, she was cleared of all charges. She was officially rehabilitated on February 28, 2014. Just after Euromaidan revolution, the Ukrainian Supreme Court closed the case and found that "no crime was committed".
By November 2011 Tymoshenko was under criminal investigation for ten criminal acts;Ukrainian prosecutors have claimed she has committed more criminal acts. The cases are:
In addition Tymoshenko's lawyer Serhiy Vlasenko stood accused of car theft, robbery and failing to obey a court ruling stemming from his divorce.
On 11 October 2011, a Ukrainian court sentenced Tymoshenko to seven years in prison after she was found guilty of abusing her office when brokering the 2009 gas deal with Russia.
From 5 August 2011 till her release Tymoshenko had been in custody. At first she was held in Kiev, and since December 30, 2011 Tymoshenko has been imprisoned in Kharkiv. Since May 2012 she was hospitalized and received treatment for a spinal disc herniation Tymoshenko was on three hunger strikes during her imprisonment.
Representatives of several countries and human rights organizations have rated the trials against Tymoshenko as "selective justice" and "political persecution". The European Union has shelved the European Union Association Agreement and Deep and Comprehensive Free Trade Agreement with Ukraine and EU leaders have suggested that these agreements will not be ratified unless Ukraine addresses concerns over a "stark deterioration of democracy and the rule of law", including the imprisonment of Tymoshenko and Yuriy Lutsenko in 2011 and 2012.
