The right to request evidence is the most important right of the defense attorney to influence the nature and scope of evidence collection in criminal proceedings. When used correctly, a request for evidence can have effects in multiple directions: it expands the court's obligation to clarify matters during the main hearing, allows for the documentation of the facts established during the evidence collection, and often serves as a basis for a successful appeal. Although the issue of evidence is the central problem of criminal proceedings, the developments in recent years aimed at restricting the right to request evidence in legislation and higher court rulings are unmistakable. The continuous tightening of the requirement of connection or the deadlines for submitting evidence requests are examples of legal creations that limit the scope of the right to request evidence.
