Unless further information has been ordered, the Investigating Chamber shall rule at the latest within twenty working days of the statement of appeal, by a reasoned order made in chambers.
If the Investigating Chamber deems it necessary to hear the person placed under judicial supervision, it may use the means of telecommunication mentioned in Article 706-71, whether the person in question is living on the territory of the Republic or abroad.
The investigating chamber may, by a measure of judicial administration, authorise the issuing State to intervene at the hearing through a person authorised by that same State for that purpose. Where the issuing State is authorised to intervene, it shall not become a party to the proceedings.
Where the Investigating Chamber considers raising one of the grounds for refusal provided for in 1° to 3° of Article 696-73 or 2° of article 696-74, there is no need to inform the competent authority of the issuing State if this information has already been provided by the public prosecutor or by the liberty and custody judge pursuant to Article 696-72.
