In January 2006, the Ministry of Internal Affairs of Ukraine started an official investigation of the allegedly false acquittal of the criminal convictions which Yanukovych received in his youth. Yuriy Lutsenko, the head of the ministry, announced that forensic tests proved the forgery of the respective documents (issued in instead of 1978) and initially claimed that lack of the formal acquittal precluded Yanukovych from running for the seat in the 2006 parliamentary election. However, the latter statement was corrected within days by Lutsenko himself who conceded that the outcome of the investigation into the legality of the Yanukovych's acquittal could not affect his eligibility to run for the parliament seat since the deprivation of his civil rights due to the past convictions would have expired anyway due to the statute of limitations. Viktor Yanukovych's Party of Regions won the 2006 Ukrainian parliamentary election.
