Criminal cases and imprisonment
On 13 December 2010, Lutsenko was charged with abuse of office and forgery by Prosecutor General of Ukraine Viktor Pshonka. On 5 November, it was already announced that Lutsenko faced criminal charges for an alleged financial crime involving a less than $5,000 overpayment to his driver. According to Lutsenko the criminal case against him is political persecution. Pshonka has denied this. Lutsenko was also charged with having signed an order whilst on holiday and not having cancelled the traditional "National Militia Day" despite a general instruction from the then Prime Minister to make budgetary savings where possible. Lutsenko has been jailed since 26 December 2010 in Kyiv's Lukyanivka Prison. Lutsenko was arrested near his home on 26 December; on 27 December a court ordered his arrest on the grounds that he had been dodging questioning in violation of his written pledge not to leave Kyiv. Three criminal cases opened against him where merged into one on 27 January 2011. Lutsenko went on a hunger strike from 22 April till 24 May 2011 in protest against his "preventive punishment".
Lutsenko filed a complaint in a U.S. court on 14 December 2011 against his (Ukrainian) prosecutors, made possible by the Alien Tort Statute, for "illegal arrest and arbitrarily prolonged detention".
On 27 February 2012, after a pre-trial detention of 14 months, Lutsenko was sentenced to fours year in jail (with confiscation of his property) for embezzlement and abuse of office. Lutsenko immediately after his sentence stated he will appeal against sentence. The European Commission stated the day of his sentence "signals the continuation of trials in Ukraine which do not respect international standards as regards fair, transparent and independent legal process"; Spokesperson for the United States Department of State Victoria Nuland stated the cases raised "serious concerns about the government of Ukraine's commitment to democracy and the rule of law"; other Council of Europe member have criticised the sentence in similar wording. In a statement issued by the Parliamentary Assembly of the Council of Europe (PACE) right after the verdict of 27 February 2012 Lutsenko was named "the victim of a political vendetta"; the next day the President of PACE Jean-Claude Mignon called for his release. Human rights organizations have urged the high courts in Ukraine to overturn the verdict against Lutsenko. On 29 February 2012, the European People's Party demanded "immediate release of Yulia Tymoshenko, Yuriy Lutsenko and other political prisoners; it also insisted the Association Agreement between Ukraine and the European Union should not be signed and ratified until these demands were met. An appeal to the sentence was filed 7 March 2012. Since the EU has shelved the European Union Association Agreement and Deep and Comprehensive Free Trade Agreement with Ukraine because of the imprisonment of him and Tymoshenko.
The European Court of Human Rights (ECHR) considered a complaint lodged by Lutsenko on 17 April 2012, in which Lutsenko claimed his arrest and the decision on his detention were arbitrary and unlawful. On 3 July 2012, the ECHR stated that the arrest of Lutsenko violated his human rights and the court ordered the government of Ukraine to pay €15,000 to Lutsenko as compensation for moral damages.
On 17 August 2012, Lutsenko was sentenced to two years in prison for the extension of an investigative case concerning Valentyn Davydenko, the driver of former Security Service of Ukraine First Deputy Chief Volodymyr Satsiuk, as part of an investigation into the poisoning of then presidential candidate Viktor Yuschenko. The European Union, the United States Department of State, Canada and several human rights organizations protested the sentence and called into question the independence of the legal process that had led to it. He served his time in a prison in the city of Mena. During his imprisonment Lutsenko was moved several times to hospital to receive medical treatment.
Lutsenko lost his appeal on 3 April 2013; this High Court ruling could be challenged in any other Ukrainian court.
The judges of the Higher Specialized Court on Civil and Criminal Cases will on 10 April 2013 announce a ruling on the appeal against the second conviction of Lutsenko regarding the poisoning of former Ukrainian President Viktor Yushchenko; this will not influence the term of Lutsenko's imprisonment.
After already having suggested it earlier, President Viktor Yanukovych on 5 April 2013 proposed the presidential commission on pardons urgently to consider the request by Verkhovna Rada Human Rights Commissioner Valeriya Lutkovska to pardon Lutsenko. The requests to pardon Lutsenko was made by Ukrainian parliamentary Lutkovska, former President of the European Parliament Pat Cox and former Polish President Aleksander Kwasniewski. Lutkovska asked to pardon Lutsenko "due to the European standards of human rights, which include providing effective medical care to persons detained in prisons". On 7 April 2013, a decree by Yanukovych pardoned Lutsenko (among others) for health reasons and "to decriminalize and humanize Ukrainian legislation" and the same day he was released from prison. The decree also exempted from further punishment Lutsenko's fellow Minister in the second Tymoshenko Government Heorhiy Filipchuk. Lutsenko stated the day after his release he will "continue to remain in politics".
Lutsenko and his family had repeatedly stated that they would not seek a pardon, because they believe the charges where groundless and political punishment. Nevertheless, Lutsenko's wife Iryna Lutsenko welcomed the request.
On 8 April 2013, the European Union welcomed the pardons of Lutsenko and Filipchuk, and urged Ukraine to continue addressing "the cases of selective justice".
