The cross-appeal, even if provoked, must, on pain of inadmissibility pronounced ex officio, be made in the form of a factum and contain the same particulars as the plaintiff’s factum.
The factum must, under the same penalty:
– be delivered to the registry of the Cour de cassation before the expiry of the time-limit laid down for the delivery of the factum in reply;
– be served within the same time-limit on the lawyers of the other parties to the cross-appeal. If, in matters where representation is compulsory, the defendant has not constituted a lawyer, the statement of case must be served on him at the latest within one month of the expiry of that period; however, if, in the meantime, the defendant constitutes a lawyer before service of the statement of case, his lawyer shall be served.
The defendant to such an appeal shall have a period of one month from the date of service to submit, and if appropriate serve, his statement of case in response.
