Former Deputy Prime Minister Jan Hamáček failed to appeal a verdict against him, and the Prague 5 District Court ruling has become definitive as a result. He sued news server Seznam Zprávy for CZK 10 million for defamation over articles about a planned trip to Moscow. Seznam Zprávy said Hamáček planned to use findings about Russian involvement in the explosion in Vrbětice as leverage to get Sputnik V vaccine from Russia and other benefits. In the end, the meeting did not take place. Hamáček now must pay the court fees and also reimburse Seznam Zprávy for their legal expenses. A criminal investigation against Hamáček by the National Center Against Organized Crime (NCOZ) was previously dropped as the trip was only in the planning stages.
