Abstract This paper looks at ways of speeding up domestic criminal proceedings. Both the Charter of Fundamental Rights of the European Union and the case law of the European Court of Human Rights in Strasbourg encourage Member States to ensure that their courts deliver judgments within a reasonable time. The present paper deals with the new Hungarian cooperation system, including the trial waiver and the preparatory session, which is a pre-trial meeting in the court phase. These have achieved significant results in speeding up and simplifying proceedings without limiting the rights of the accused and offer a genuine rule of law solution for efficient criminal proceedings, all while preventing unjustified delays in proceedings. Initial experience in practice has shown that these Hungarian legal instruments could serve as an excellent example for countries facing similar challenges in developing criminal politics and criminal justice policies.
