Checklist: what to check before filing the defense brief under Art. 415-bis c.p.p.
2 min read · Editorial oversight: Avv. Federico Papa
This checklist should be used during the final review phase following service of the notice of conclusion of preliminary investigations. These checks ensure the document's effectiveness and the proper exercise of defense rights within statutory deadlines.
In brief
Reviewing the defense brief under Art. 415-bis c.p.p. requires compliance with the twenty-day deadline from service of the notice of conclusion of preliminary investigations. Late filing forfeits the Public Prosecutor's obligation to conduct the requested interrogation. The brief must be submitted via the Criminal Filing Portal (PDP) with a digital signature; standard certified email (PEC) renders the filing inadmissible. Effectiveness depends on a full case file review, specific requests for further investigative acts, and accurate identification of the R.G.N.R. number and client data to support a motion for dismissal.

Check compliance with the twenty-day deadline

Late filing results in the loss of the Prosecutor's obligation to conduct the requested interrogation, whereas for other requests the Prosecutor retains discretion to evaluate their relevance.
- 2.
Confirm full review of the case file
Ensure that all documents filed by the Prosecutor have been thoroughly reviewed before drafting submissions or requests. Submitting requests or asking for an interrogation without full knowledge of the case file exposes the client to the risk of making prejudicial statements.
- 3.
Verify the specificity of requests for further investigative acts
Ensure that requests for further investigative acts are not generic, but specify precisely the activities to be performed. Omitting such details or providing vague indications results in the rejection of the request for lack of specificity.
- 4.
Check consistency with the provisional charge
Check that the defense legal arguments respond precisely to the charges described in the notice under Art. 415-bis c.p.p. A defense not focused on the contested facts reduces the document's effectiveness in persuading the Prosecutor to move for dismissal.

5.Verify the correct filing channel
Verify that filing is completed through the Criminal Filing Portal (PDP). Using non-compliant channels, such as certified email (PEC), renders the filing inadmissible or ineffective.
- 6.
Review the heading and identification data
Ensure that the assigned Public Prosecutor, case number (R.G.N.R.), client details, and defense counsel details are correctly stated. Errors in these details may prevent the proper association of the document with the case file.
- 7.
Check for the digital signature
Ensure that the file is digitally signed by defense counsel before uploading it to the portal. The absence of a valid signature renders the document inadmissible or ineffective.
- 8.
Verify the clarity of the conclusions
Ensure that the conclusions clearly state whether defense counsel is requesting a motion for dismissal, further investigative acts, or an interrogation. Ambiguous requests risk undermining the effectiveness of defense motions.

Frequently asked questions
What happens if I file the brief on the twenty-first day?
Forfeiture occurs: the Public Prosecutor is no longer required to conduct the requested interrogation. Regarding requests for further investigative acts, the Prosecutor is never under a mandatory obligation to perform them, but evaluates the relevance of defense requests at their discretion.
Can I send the brief via PEC to the magistrate?
No. Except in exceptional cases provided by law, using certified email (PEC) instead of the PDP Portal renders the filing inadmissible or ineffective under current rules governing electronic criminal proceedings.
