The opposition made by the accused, within the period provided for either in the third or fifth paragraph of Article 495-3, shall be made:
1° Either by letter addressed to the chief clerk of the court that handed down the decision. The letter must be sent within the prescribed time limit, as evidenced by the postmark;
2° Or by a declaration made to the chief clerk, recorded and signed by him and by the accused himself or by a lawyer or a special proxy. The power of attorney is attached to the document drawn up by the chief clerk.
In both cases, the accused must, in support of the objection, hand or send the letter of notification to the chief clerk or inform him of the references on it. Declarations of opposition are entered in a register.
In the event of notification by the public prosecutor or his delegate, the opposition may be made before him after this notification, by a note made on the notification form of the order, signed by the public prosecutor or his delegate and by the accused. The public prosecutor or his delegate shall immediately notify the chief clerk.
The provisions of this article shall also apply in the event of an opposition lodged by the civil party.
