CAT/C/31/D/187/2001 Page 7 4.3 The State party explains that, under the criminal justice system, the complainant may submit a complaint, from within Tunisia or abroad, to a representative of the Public Prosecutor’s Office with jurisdiction in the area in question. He may also authorize a Tunisian lawyer of his own choice to submit the complaint or request a foreign lawyer to do so with the assistance of a Tunisian colleague. 4.4 Under the same rules of criminal procedure, the Public Prosecutor will receive the complaint and institute a judicial enquiry. In accordance with article 53 of the Code of Criminal Procedure, the examining magistrate to whom the case is referred will hear the author of the complaint. In the light of this hearing, he may decide to hear witnesses, question suspects, undertake on-site investigations and seize physical evidence. He may order expert studies and carry out any actions which he deems necessary for the uncovering of evidence, both in favour of and against the complainant, with a view to discovering the truth and verifying facts on which the trial court will be able to base its decision. 4.5 The State party explains that the complainant may, in addition, lodge with the examining magistrate during the pre-trial proceedings an application for criminal indemnification for any harm suffered, over and above the criminal charges brought against those responsible for the offences against him. 4.6 If the examining magistrate deems that the public right of action is not exercisable, that the acts do not constitute a violation or that there is no prima facie case against the accused, he shall rule that there are no grounds for prosecution. If, on the other hand, the magistrate deems that the acts constitute an offence punishable by imprisonment, he shall send the accused before a competent court - which in the present instance, where a serious offence has been committed, would be the indictment chamber. All rulings by the examining magistrate are immediately communicated to all the parties to the proceedings, including the complainant who brought the criminal indemnification proceedings. Having been thus notified within a period of 48 hours, the complainant may, within four days, lodge an appeal against any ruling prejudicial to his interests. This appeal, submitted in writing or orally, is received by the clerk of the court. If there is prima facie evidence of the commission of an offence, the indictment chamber sends the accused before the competent court (criminal court or criminal division of a court of first instance), having given rulings on all the counts established during the proceedings. If it chooses, it may also order further information to be provided by one of its assessors or by the examining magistrate; it may also institute new proceedings, or conduct or order an inquiry into matters which have not yet been the subject of an examination. The decisions of the indictment chamber are subject to immediate enforcement. 4.7 A complainant seeking criminal indemnification may appeal on a point of law against a decision of the indictment chamber once it has been notified. This remedy is admissible when the indictment chamber rules that there are no grounds for prosecution; when it has ruled that the application for criminal indemnification is inadmissible, or that the prosecution is time-barred; when it has deemed the court to which the case has been referred to lack jurisdiction; or when it has omitted to make a ruling on one of the counts.
