Chapter 9. On supervision and prosecution Art. 1. The Chancellor of Justice shall monitor that the limits set in this Act for the freedom of the press are not transgressed. Art. 2. The Chancellor of Justice is sole prosecutor in cases concerning of-fences against the freedom of the press. No one other than the Chancellor of Justice may institute a preliminary investigation concerning offences against the freedom of the press. Only the Chancellor of Justice and a court of law may approve coercive measures on suspicion that such an offence has been committed, unless otherwise provided in this Act. The Government has the right to report printed matter to the Chancellor of Justice for prosecution on account of an offence against the freedom of the press. It may be laid down in an act of law that legal proceedings on account of an offence against the freedom of the press may be instituted only with the Government’s consent. The Chancellor of Justice is likewise sole prosecutor in freedom of the press cases which are not cases concerning offences against the freedom of the press, and in cases otherwise relating to violations of regulations contained in this Act: provisions of law however regulate the right of the Parliamentary Ombudsman to act as prosecutor in cases of this nature. Art. 3. Legal proceedings on account of an offence against the freedom of the press shall be instituted, in the case of a periodical for which a valid certificate of no legal impediment to publication existed at the time of publication, within six months, and in the case of other printed matter, within one year from the date of publication, with effect that the matter shall otherwise be exempt from such proceedings. This provision notwithstanding, if such proceedings have been instituted within the time specified, fresh proceedings may nevertheless be instituted against another person who is liable in respect of the offence. Provisions of law governing the period within which an offence must be prosecuted if penal sanctions are not to lapse apply also with respect to offences against the freedom of the press. 233
