In all matters, the duration of the investigation may not exceed a reasonable period in view of the seriousness of the acts alleged against the person under investigation, the complexity of the investigations required to ascertain the truth and the exercise of the rights of the defence.
If, at the end of a period of two years from the opening of the investigation, the investigation has not been completed, the examining magistrate shall issue an order giving reasons by reference to the criteria set out in the previous paragraph, explaining the reasons for the length of the proceedings, including the indications that justify the continuation of the investigation and specifying the prospects for a settlement. This order is communicated to the President of the Investigating Chamber who may, by petition, refer the matter to that court in accordance with the provisions of Article 221-1.
The order provided for in the previous paragraph must be renewed every six months.
