The person under investigation or the witness may, within ten days of being informed of the content of the geolocation operations carried out within the framework provided for in article 230-40, contest, before the president of the investigating chamber, the use of the procedure provided for in that same article. If he or she considers that the geolocation operations were not carried out properly, that the conditions set out in the said article have not been met or that the information referred to in the said article is essential for the exercise of the rights of the defence, the president of the investigating chamber shall order the geolocation to be cancelled. However, if he considers that knowledge of this information is not or is no longer likely to seriously endanger the life or physical integrity of a person, the members of his family or his close relations, he may also order that the request and the report mentioned in the last paragraph of the same article be added to the file. The president of the investigating chamber will give a reasoned decision, which may not be appealed, in the light of the documents in the proceedings and those in the file referred to in the same paragraph.
