How to draft the memorandum under Art. 378 c.p.c. with AI

4 min read · Updated September 2026 · Editorial oversight: Avv. Federico Papa

The memorandum (memoria) under Art. 378 c.p.c. is the final written defense before the public hearing at the Supreme Court (Corte di Cassazione). This document allows parties to further illustrate their grounds of appeal and respond to the Public Prosecutor's conclusions.

In brief

The Art. 378 c.p.c. brief must be filed at least five days before the public hearing. Its purpose is purely illustrative: introducing new grounds for appeal or expanding the scope of the case (tema decidendum) is strictly prohibited. The document clarifies positions already taken in the main appeal or cross-appeal, responding to the Public Prosecutor (P.M.) or new case law. Using edit.legal, practitioners can automate the consistency check with prior filings and ensure compliance with the principle of self-sufficiency (autosufficienza).

The steps

1.
Verification of the hearing type
Before drafting, ensure the appeal is scheduled for a public hearing (udienza pubblica) rather than a chamber proceeding (adunanza in camera di consiglio). Art. 378 c.p.c. specifically applies to public oral arguments. If the case follows the chamber procedure (Art. 380-bis or 380-bis.1 c.p.c.), the deadlines and filing methods differ: 5 or 10 days respectively. This distinction is critical to avoid forfeiture or the filing being declared inadmissible.
2.
Calculating the filing deadline
The brief must be filed within the mandatory deadline of at least five days before the hearing. In calculating backward deadlines, according to consolidated case law (e.g., Cass. No. 15724/2011), only the starting day (dies a quo), which is the day of the hearing, is excluded. For instance, if the hearing is on a Wednesday, the last valid filing day is the preceding Friday. Late filing makes the memorandum inadmissible, and the Court will not consider it during the deliberation of the judgment.
3.
Adhering to the limits of previously filed grounds
The content of the brief must be limited to illustrating the grounds already presented in the main appeal (ricorso) or cross-appeal (controricorso). It is strictly forbidden to introduce new complaints or raise new issues, unless they involve matters that the court can examine ex officio (rilevabili d'ufficio) at any stage and which have not yet been decided. The goal is to deepen the arguments in light of the Public Prosecutor's written conclusions or to highlight the orientation of recent United Sections (Sezioni Unite) rulings affecting the case.
4.
Analyzing the Public Prosecutor's conclusions
One of the primary purposes of the Art. 378 c.p.c. brief is to respond to the Public Prosecutor's (P.M.) conclusions, if filed. You must analytically refute the logical-legal steps through which the P.M. suggests granting or dismissing the appeal. At this stage, edit.legal can assist the practitioner in quickly comparing the text of the conclusions with the grounds of appeal to identify friction points that require a more vigorous and technical defense.
5.
Conciseness and clarity of presentation
The Court of Cassation requires compliance with the principles of conciseness (sinteticità) and clarity. The memorandum should not be a literal repetition of the appeal but a targeted focus on crucial issues. It is advisable to use a bulleted structure, referencing the numbers of the original appeal grounds. An excessively verbose or confused brief risks obscuring the defense's strengths at the critical moment preceding the Supreme Court's decision.
6.
Electronic filing at the Supreme Court
The filing of the brief must be done exclusively electronically via the Electronic Services Portal (PST) or practice management software. It is essential to ensure the file is in text-searchable PDF format: not a scan: and that the digital signature is valid (PAdES or CAdES format). After sending, monitor for the fourth PEC (certified email) receipt (ricevuta di avvenuta consegna), which confirms the timeliness of the filing and the correct entry of the document into the Supreme Court's electronic file.

Mistakes to avoid

Introducing new grounds of appeal not present in the original filing.
Filing beyond the 5 days deadline (incorrect calculation of backward terms).
Failure to respect page limits or clarity criteria set by Court protocols.
Using the Art. 378 brief for chamber proceedings governed by Art. 380-bis.1.
Including new evidence or documents not related to admissibility or the nullity of the judgment.

Frequently asked questions

Can new documents be produced with the Art. 378 c.p.c. brief?

No, producing new documents is not allowed in Supreme Court proceedings, except for those regarding the nullity of the challenged judgment or the admissibility of the appeal and cross-appeal, as provided by Art. 372 c.p.c.

What happens if the 5-day deadline falls on a Saturday or Sunday?

Since it is a backward deadline (termine a ritroso), if it falls on a holiday or Saturday, it must be moved earlier to the first preceding working day, in compliance with the rules for non-clear terms.

Is the brief mandatory in order to conduct oral arguments?

No, the memorandum is optional. However, it is highly recommended to establish the key points of the defense and respond to the P.M.'s remarks before the judges enter the deliberation chamber.
