The liberty and custody judge rules by means of a reasoned order. When he orders or extends pre-trial detention or rejects an application for release, the order must include a statement of the legal and factual considerations on the inadequacy of the obligations of judicial supervision or house arrest with electronic surveillance and the reason for detention by reference solely to the provisions of the articles 143-1 et 144. In criminal cases, decisions extending pre-trial detention beyond eight months or rejecting an application for release concerning detention of more than eight months must also include a statement of factual considerations on the inadequacy of the obligations of house arrest with mobile electronic surveillance, provided for in the third paragraph of article 142-5 and in Article 142-12-1, or the electronic device provided for in Article 138-3, where this measure may be ordered in view of the nature of the offences charged.
In all cases, the order is notified to the person under investigation, who receives a full copy of it against signature in the proceedings file.
