The procedure is not currently regulated in the Czech Republic. Everyone who has a thing important for criminal proceedings has an obligation to render it to authorities active in criminal proceeding (a court, a public prosecutor, a police body). These authorities do not issue any order. The obligation to produce documents does not apply to documents which contain information with respect to which producing a testimony is not possible (i.e. classified information or information covered by an obligation of secrecy) unless the person who possesses such document was relieved of the obligation of secrecy. Where there is a need to secure documentary evidence, an EIO can be applied (for states that apply the EIO Directive) or an MLA request.
