Principle of accusatorial procedure states that criminal proceedings should be conducted only upon the request of a party and thus, the court cannot take the initiative. By the Act of 11 March 2016 the courts’ right to demand supplementing preparatory proceeding during preliminary verification of indictment has been brought back to the criminal procedure. The possibility of adjourning or defer- ring the trial in order to demand additional evidence has also been restored. The aim of the paper is to consider how these court powers affect the principle of accusatorial procedure and to answer the question whether departure from this principle is justified, for example, by the need to comply with other principles of criminal proceedings.
