Drafting a motion for nullità relativa (relative nullities) requires strict adherence to the statutory deadlines provided by the Italian Code of Criminal Procedure. This guide explains how to identify the defect and draft a motion effectively to avoid dismissal.

In brief

A motion for nullità relativa (relative nullity) under Art. 181 c.p.p. must be raised by the interested party within mandatory deadlines, otherwise the defect is cured. Unlike absolute nullities, these cannot be raised by the court ex officio and require proof of a specific legal interest. Counsel must raise the exception during indagini preliminari (preliminary investigations), the udienza preliminare (preliminary hearing), or, at the latest, during the questioni preliminari al dibattimento (preliminary trial motions) under Art. 491 c.p.p., depending on when the breach occurred.

The steps

1.
Verification of the nature of the defect and category
The first step is to ensure the violation falls under nullità relative (relative nullities), which are residual in nature. Under Art. 181 c.p.p., nullities other than absolute (Art. 179) or intermediate (Art. 180) are considered relative. Counsel must precisely identify the breached procedural rule and verify that the law does not provide for a more severe classification of the defect. using edit.legal, you can analyze the case to confirm the correct legal classification of the motion before filing.
2.
Analysis of deadlines and procedural bars
Relative nullities are subject to strict termini di decadenza (statutory deadlines). If the defect occurs during indagini preliminari or the udienza preliminare, it must be raised before the end of the hearing. If it occurs in the decree ordering the trial or in the pre-trial phase, it must be raised within the deadline set by Art. 491 paragraph 1 c.p.p. Failure to meet these deadlines results in the curing of the nullity. edit.legal helps monitor procedural deadlines based on the current stage of the criminal proceedings.
3.
Assessment of legal interest and standing
According to Art. 182 c.p.p., a nullità relativa cannot be raised by the party who caused it or contributed to it, nor by a party who lacks a interesse ad agire (legal interest) in the observance of the breached provision. When drafting the motion, it is essential to argue how the violation caused actual prejudice to the party's rights. A purely formal complaint is insufficient, you must describe the impact of the defect on the defense strategy or the regularity of the fact-finding process. edit.legal suggests specific clauses to justify the legal interest in the action.
4.
Drafting the technical content of the motion
The document must contain a precise indication of the breached provision and the facts that led to the defect. If the motion concerns an investigative act, the protocol number or the date of the flawed record must be cited. You must explicitly request that the judge declare the act null and specify which subsequent acts should be considered null by derivation under Art. 185 c.p.p. Clarity is crucial to allow the judge to make an immediate decision, especially if the exception is raised orally during a hearing for the record.
5.
Filing and recording in the minutes
The motion can be submitted via a memoria (written brief) or an oral statement. If raised during a hearing, counsel must ensure that the essential terms of the complaint are accurately recorded in the verbale d'udienza (hearing minutes). It is advisable to hand a written note to the clerk to supplement the record, reducing the risk of omissions. If rejected, the motion must be reintroduced as a ground for appeal, provided it was timely raised in the previous merit stage. edit.legal allows for the rapid generation of filing briefs to be attached to the minutes.

Mistakes to avoid

Raising the motion after the deadline for questioni preliminari al dibattimento (preliminary trial motions).
Failing to demonstrate the specific legal interest required by Art. 182 c.p.p.
Confusing a relative nullity with an intermediate one, resulting in incorrect timing.
Failing to request the extension of nullity to dependent acts under Art. 185 c.p.p.

Frequently asked questions

What happens if the motion for relative nullity is not raised within the deadlines?

If not raised within the deadlines established by Art. 181 c.p.p., the nullity is considered sanata (cured) and can no longer be invoked in any subsequent stage of the trial.

Can the judge raise a relative nullity ex officio?

No, relative nullities can only be declared upon a party's motion, unlike absolute nullities which can always be raised by the court ex officio.

What is the final deadline for nullities occurring during the trial?

Nullities occurring during the trial must be raised immediately or, if that is not possible, within the appeal against the final judgment.
