The opinion presents Sejm’s draft position in the proceedings before the Constitutional Tribunal concerning constitutionality of the procedure for the creation of common and military courts (Ref. No. K 27/12). A group of Deputies and the National Council of the Judiciary, initiating the proceedings, challenged the transfer to create and dissolve common and military courts to – respectively – the Minister of Justice and Minister of National Defence. In the Sejm’s view, the procedure for creation common courts does not infringe constitutional standards, but the provision authorising the creation of military courts does not comply with the Constitution due to the lack of necessary guidelines.
