In April, 2011, Bárta was accused of bribery by his colleagues from Public Affairs, deputies Jaroslav Škárka, Stanislav Huml, and Kristýna Kočí. The deputies were subsequently expelled from the party. The incident caused serious problems in the Czech government coalition.
On 8 April 2011, Bárta announced his resignation from the government of Petr Nečas.
A year later, in April 2012, Barta was convicted of bribery and conditionally sentenced to 18 months of imprisonment.
