How to draft the amendment of the charge under Art. 516 c.p.p. with AI

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

Amending the charge during the trial evidentiary phase is an essential act to maintain the principle of correlation between the accusation and the judgment. Article 516 c.p.p. allows the Public Prosecutor to adjust the charge when a 'fatto diverso', a different fact, emerges compared to what was originally contested. Correct execution of this procedure prevents the judgment from being declared null and guarantees the right to a fair hearing.

In brief

The amendment of the charge under Art. 516 c.p.p. occurs when the facts appear different from their description in the indictment, provided they remain within the judge's jurisdiction. The Prosecutor performs an oral contestation in court if the defendant is present, or via formal service if absent. Following the amendment, the defendant is entitled to a 'termine a difesa', time to prepare a defense, and may request alternative trial procedures. Precision in describing the updated facts is fundamental for the validity of the proceeding.

The steps

1.
Verifying the grounds for the 'fatto diverso'
The first step is to ascertain that the trial evidence has outlined a 'fatto diverso', understood as a variation in the constitutive elements of the conduct or circumstances of time and place, while maintaining a common core with the original charge. It must not be a completely new fact, which would require the application of Art. 518 c.p.p. The amendment must remain within the subject-matter jurisdiction of the presiding judge. edit.legal can assist in comparing trial transcripts with the initial indictment to identify these shifts.
2.
Drafting the new contestation
The Public Prosecutor must formulate the amendment by analytically specifying which elements of the fact have changed. It is necessary to describe the conduct, the event, and the causal link in accordance with the new evidence, such as testimonies or expert reports. Clarity is fundamental: a generic or ambiguous contestation infringes upon the right of defense. The act must be recorded in the trial minutes. By using edit.legal, you can generate a draft that automatically integrates new evidentiary findings into the technical format required by the code of criminal procedure.
3.
Performing the contestation in court
If the defendant is present in court, the contestation is performed orally by the Public Prosecutor reading the amendment. The Presiding Judge must ensure the defendant understands the content of the variation. If the defendant is absent, the amendment must be served as an excerpt of the minutes by the Prosecutor, ensuring the recipient has legal knowledge of it before the trial continues. This step is protected by 'nullità a regime intermedio' (intermediate nullity), pursuant to Art. 522 c.p.p., in case of omission.
4.
Managing the 'termine a difesa'
Following the amendment, the defense counsel has the right to request a 'termine a difesa' to prepare a new defense strategy. This period cannot be shorter than that provided by Art. 429 c.p.p., as established by Art. 519 c.p.p., unless expressly waived. During this time, the trial proceedings may be suspended. Failure to grant this time, if requested, results in the invalidity of subsequent acts. edit.legal allows for the rapid calculation of procedural deadlines related to the resumption of the trial after suspension.
5.
Evidence rights and alternative procedures
Following the amendment of the charge, the defendant has the right to request the admission of new evidence relating to the contested different fact. Furthermore, according to the Constitutional Court's rulings, the defendant may request alternative trial procedures, such as 'giudizio abbreviato' (summary judgment) or 'patteggiamento' (plea bargaining), specifically regarding the modified fact or if the amendment concerns aspects that were not foreseeable at the start of the trial. Drafting the post-amendment defense brief must account for these strategic options to maximize client protection.

Mistakes to avoid

Confusing a 'fatto diverso' (Art. 516) with a 'fatto nuovo' (Art. 518).
Forgetting to serve the amendment to an absent defendant, leading to the nullity of the judgment.
Amending the charge beyond the judge's subject-matter jurisdiction.
Denying the 'termine a difesa' requested by the counsel after the new contestation.

Frequently asked questions

What happens if the emerged fact is completely new?

If a completely new fact emerges, meaning a distinct historical event not mentioned in the decree, Art. 518 c.p.p. applies. The Prosecutor can only contest it with the defendant's consent and if it does not prejudice the trial's efficiency, otherwise, they must proceed separately.

Can the charge be amended during appeal?

No, the amendment of the charge under Art. 516 c.p.p. is a procedure typical of the first-instance trial during the evidentiary phase. In the appeal stage, the judge can only give the fact a different legal definition under Art. 521 c.p.p.

Is the defense timeframe mandatory?

The 'termine a difesa' must be granted upon the party's request. It is not automatic, but the judge is obliged to inform the defendant of their right to request it following the amendment of the charge.
