Since 1 October 2008 the Supreme Administrative Court (SAC) has become a disciplinary court for judges and state prosecutors under the Act No. 314/2008 Coll., which amended the Act on Courts and Judges (No. 6/2002 Coll.) and the Act on Proceedings in Matters of Judges and State Prosecutors (No. 7/2002 Coll.). As for judges, the disciplinary proceedings are brought by the President of the Czech Republic, Minister of Justice or by the president of a respective court (District, Regional, High, Supreme and Supreme Administrative Court). The proceedings against court officials can be brought by the President of the Czech Republic, Minister of Justice, the Ombudsman and by officials against their underlings. The President of the SAC can bring the proceeding against an official for administrative matters of Regional Court. As for the prosecutors, the proceedings are brought by the Minister of Justice and by the Prosecutor General in regards to any prosecutor. The lower instances have this power only within their office and over even lower instances, i.e. The High Prosecuting Attorney’s Office can start the proceedings against its prosecutor or the prosecutor of Regional Prosecutor's Office or the District Prosecutor's Office.

Under Act No. 183/2009 Coll. (Amendment to the Enforcement Code) the SAC has also become a disciplinary court for enforcement agents since 26 June 2009. Disciplinary chambers that deal with disciplinary matters of judges are supposed to also deal with these disciplinary matters. Under the transitional provisions of the Act, the SAC should also decide the cases not resolved by 26 June 2009 by the Disciplinary Committee (a dissolved body of the Enforcement Agents Chamber) as well as cases in which the committee had taken a decision but failed to produce a written decision and to send it to the agent charged with a disciplinary offense. Shortly after this amendment, the regulation of the disciplinary procedure in matters of enforcement agents changed again and according to Act No. 286/2009 Coll. (Amendment to the Enforcement Code), as from 1 November 2009, a Disciplinary Court for Enforcement Agents was established at the SAC.
