The interrogation of suspects by the police has been a subject of debate in the field of criminal procedural law for years. Following the judgment of the European Court of Human Rights in the Salduz v. Turkey case, the rights of suspects during police interrogation have been recognized even in the preliminary proceedings. As a result of this judgment, the European Parliament and the Council have issued several directives regulating this area. In Croatian law, the examination of suspects by the police was introduced through an amendment to the Criminal Procedure Act in 2017. This study analyzes the process of introducing this evidentiary action, the regulation of the evidentiary action, and the rights afforded to suspects during the interrogation process. The research covers European and Croatian legislation, key judgments of the European Court of Human Rights in this field, and a significant part is dedicated to domestic judicial practice, illustrating how successfully Croatian legislation has implemented European directives. The study also addresses problems that have arisen during the application of new provisions and explores potential solutions.
