During the investigation in flagrante delicto or the preliminary investigation, the liberty and custody judge, at the request of the public prosecutor, may order by reasoned decision the seizure, at the advanced expense of the Treasury, of the property or intangible rights the confiscation of which is provided for by the article 131-21 of the Penal Code. The examining magistrate may, in the course of the investigation, order this seizure under the same conditions.
The decision taken pursuant to the first paragraph is notified to the public prosecutor, the owner of the property or right seized and, if known, to third parties with rights to this property or right, who may refer it to the president of the examining chamber or to the examining chamber by declaration at the court registry within ten days of notification of the decision. This appeal does not have suspensive effect. The appellant is only entitled to have the documents relating to the seizure he is contesting made available to him. If they are not appellants, the owner of the property and third parties may nevertheless be heard by the president of the investigating chamber or the investigating chamber, without however being able to claim to have the proceedings made available.
