Article 154 of Code of Civil Procedure

The Registry shall enter the appeal in the register maintained for that purpose on the day the petition and its attachments are submitted. No later than the following day, it shall deliver the original petition, its copies, and the explanatory memorandum—if any—to the court's Process Service Section for service and return of the original. It shall also attach the case file in which the appealed judgment was rendered, with all its contents, within one week at most. If the respondent in the appeal wishes to submit his defense, he shall deposit with the Registry, within fifteen days from the date of service of the appeal upon him, a memorandum of his defense and copies thereof equal to the number of litigants. He may attach thereto the documents he wishes to submit. Memoranda or documents submitted by the litigants after the specified time limits may not be accepted. Instead, the Registry shall prepare a record, to be attached to the file, stating what has been submitted, the date of its submission, its contents, and the name of the person who submitted it, recording its return to him. After the expiry of the foregoing time limits, the Cassation Prosecution shall deposit a memorandum of its opinion on the grounds of appeal, or endorse that opinion on the appeal file if that is sufficient, and return it to the Registry, all within a period not exceeding sixty days from the date on which the Registry sent it thereto. The appeal shall be presented to the court sitting in chambers, accompanied by the opinion of the Cassation Prosecution. If the court considers it inadmissible because of a defect in form, invalidity of its procedures, or its being based on grounds other than those set out in Article (152) of this Law, it shall rule it inadmissible by an unappealable decision, with brief reasons recorded in the minutes of the hearing. If the court considers otherwise, it shall set a hearing to consider the appeal. (2)
