The exception for lack of competence (eccezione di incompetenza) is a fundamental procedural tool to ensure the right to a natural judge established by law. This guide explains how to properly draft and raise this objection within the strict statutory deadlines of the Italian Code of Criminal Procedure.

In brief

To correctly draft an exception under Art. 21 c.p.p., the lawyer must distinguish between subject-matter competence (materia), territorial competence (territorio), or competence by joinder (connessione). While lack of subject-matter competence can be raised at any stage, territorial or joinder-based incompetence must be raised, under penalty of forfeiture, during the preliminary hearing or before the trial begins. The motion must explicitly identify the competent court and provide the factual and legal grounds justifying the transfer of the proceedings.

The steps

1.
Classification of the type of incompetence
The first step is to determine whether the lack of competence concerns subject matter (incompetenza per materia), territory (per territorio), or joinder (per connessione). Subject-matter incompetence is the most severe and can be raised at any stage or degree of the trial, except for cases of 'excessive competence' (a higher court handling a case belonging to a lower court). Conversely, territorial and joinder-based incompetence must follow strict deadlines. Correct classification is essential to identify the legal window for filing the motion and to avoid irreversible procedural forfeitures.
2.
Verification of statutory deadlines
Compliance with the deadlines set by Art. 21 c.p.p. is the most critical aspect. If a preliminary hearing (udienza preliminare) is scheduled, territorial or joinder incompetence must be raised before its conclusion. If the motion is rejected, it must be re-submitted during the preliminary trial matters under Art. 491 c.p.p. In proceedings without a preliminary hearing, the deadline is the moment the court verifies the parties' appearance at trial. edit.legal assists in monitoring these deadlines by analyzing the current procedural phase. Failure to meet these deadlines results in the validation of the judge's competence, precluding further objections.
3.
Identification of the competent court
The exception cannot merely deny the current court's competence; it must mandatory indicate which court is deemed competent by the defense. One must apply the rules of Art. 8 and 9 c.p.p. for territorial jurisdiction (place where the crime was committed, or alternatively, where the last act occurred or the defendant's residence/abode) and the subject-matter distribution tables. If the lack of competence arises from a joinder of proceedings, Art. 12 et seq. c.p.p. must be cited. A generic motion that fails to specify the correct alternative venue risks being declared inadmissible by the court or the single judge.
4.
Drafting factual and legal grounds
The reasoning must be analytical. You must describe the locus commissi delicti (place of the crime) as emerging from the investigation files and compare it with the court's district. If contesting subject-matter competence, analyze the specific charge and the statutory penalty to verify if jurisdiction belongs to the Court of Assize, the Tribunal, or the Justice of the Peace. It is crucial to attach or reference documents within the prosecutor's file that prove the different location of the crime or a different legal classification. Clarity in presentation is vital to guide the judge's decision, which will be issued via order (ordinanza) or judgment (sentenza).
5.
Filing and raising the exception
The exception can be submitted in writing via a memorandum filed electronically or handed over during the hearing, or stated orally for the record. If raised during a hearing, it is advisable to provide the judge with a written note to facilitate recording and review of the grounds. Once the objection is raised, the judge, after hearing the other parties, decides immediately. If the judge grants the exception, they issue a judgment and order the transfer of files to the prosecutor at the competent court. Using edit.legal allows for the rapid generation of the document's structure based on the data from the indictment or the hearing notice.

Legal basis: Art. 21 c.p.p.Art. 22 c.p.p.Art. 8 c.p.p.Art. 9 c.p.p.Art. 12 c.p.p.Art. 491 c.p.p.

Mistakes to avoid

Raising territorial incompetence for the first time on appeal without having raised and maintained it in previous instances.
Forgetting to specifically indicate the court deemed competent, making the exception too generic.
Confusing subject-matter incompetence by deficiency (lower court proceeding) with incompetence by excess (higher court proceeding).
Raising the exception after the trial has opened once the deadlines under Art. 491 c.p.p. have expired.

Frequently asked questions

What happens if the territorial incompetence exception is not re-raised at trial?

If the exception was rejected during the preliminary hearing, it must be raised again during the preliminary trial matters (under Art. 491 c.p.p.) or it will be forfeited. Failure to re-raise it cures the defect, and it can no longer be used as a ground for appeal.

Is subject-matter incompetence always checkable ex officio by the judge?

Yes, subject-matter incompetence is noted ex officio at any stage and degree of the proceedings, except for 'excessive' competence (where a higher court tries a crime belonging to a lower court), which follows the same strict deadlines as territorial incompetence.

What is the effect of a declaration of incompetence on evidence already collected?

According to Art. 26 c.p.p., failure to comply with competence rules does not render previously acquired evidence ineffective. However, statements made to the incompetent judge, if repeatable, have limited evidentiary value and must generally be renewed before the competent judge.
