Yes, a letter of request for international judicial assistance in criminal matters is essential. The accused, defence counsel, victim and party to an action, proxies, appointed guardian and in proceedings before the court a public prosecutor, probation and mediation officer, high court clerk, court secretary and assistant prosecutor have the right to inspect files, with the exception of the voting record and personal data on the identity of the protected witness, endangered witness, or a witness whose identity is classified, and classified data on the identity of the agent, to take and make notes of them, and to procure copies of the files and their parts at own expense; such expenses shall not be paid by the public prosecutor, the probation and mediation officer, high court clerk, court secretary and assistant prosecutor. The same right applies to the legal representative of the accused, the victim and the party to an action, if such persons are denied their legal capacity or their legal capacity is restricted. Other persons may do so with the consent of the presiding judge and, in the preliminary hearing, with the consent of the law enforcement authority, only if it is necessary to exercise their rights. ( § 69 of the Code of Criminal Procedure). |
