The appointment of counsel for private parties other than the defendant, governed by Art. 100 c.p.p., follows specific formal rules. This guide outlines the requirements for granting technical representation to the 'parte civile' (civil claimant) and other civil entities within criminal proceedings.

In brief

Under Art. 100 c.p.p., the appointment of counsel for private parties requires a 'procura speciale' (special power of attorney). Unlike the defendant, these parties cannot appear in court without technical representation. The power of attorney must be granted via public deed or authenticated private deed, often authenticated directly by the lawyer if attached to the formal appearance. Using edit.legal ensures compliance with current procedural standards and filing requirements.

The steps

1.
Identification of subjective requirements
First, identify the specific private party: 'parte civile' (civil claimant), 'responsabile civile' (civilly liable party), or 'persona civilmente obbligata' (person liable for fine). Unlike the defendant, these parties must be represented by counsel to participate. You must verify the capacity of the grantor, particularly for legal entities, ensuring the legal representative has the authority to sign the appointment.
2.
Drafting the special power of attorney
The appointment must take the form of a 'procura speciale' (special power of attorney). Pursuant to Art. 100(1) c.p.p., it must be granted via a public deed or authenticated private writing. If the power of attorney is placed at the foot or margin of the 'atto di costituzione' (formal appearance), the lawyer may authenticate the signature. The text must explicitly mention the specific criminal proceedings and the intent to grant full representation and assistance powers.
3.
Defining scope and powers
Specifying the scope and powers is crucial. A power of attorney under Art. 100 c.p.p. is presumed to cover the entire level of proceedings unless stated otherwise. However, to perform acts that dispose of the disputed right (such as waiving an appeal), specific authorization or an 'art. 122 c.p.p.' power of attorney is required. edit.legal assists in tailoring these clauses to prevent challenges regarding the scope of authority.
4.
Authentication of the signature
If the power of attorney is not granted before a notary, the lawyer must authenticate the client's signature. This certification power is strictly limited to the signature itself. You must record the date and place of authentication and apply a digital signature for 'deposito telematico' (electronic filing). The absence of proper authentication renders the appointment void and prevents the party from legally appearing in the criminal proceedings.
5.
Electronic filing and completion
Following the 'Riforma Cartabia' (Cartabia reform), the appointment and appearance documents must be submitted via the 'Portale Deposito Atti Penali' (PDP) or other mandatory electronic channels. The main document must be a native PDF, while the power of attorney and ID documents are attached as certified digital copies. Filing must be timely, especially for the 'parte civile', observing the deadlines set by Art. 79 and Art. 484 c.p.p.

Legal basis: Art. 100 c.p.p.Art. 76 c.p.p.Art. 122 c.p.p.Art. 78 c.p.p.D.Lgs. 150/2022 (Riforma Cartabia)

Mistakes to avoid

Using a generic appointment under Art. 96 c.p.p. instead of the specific power required by Art. 100 c.p.p.
Failing to include specific powers for settlement or waiver under Art. 122 c.p.p. within the appointment.
Omitting the official capacity of the signatory when the appointment is granted by a corporate representative.
Incorrect file formatting when uploading to the 'Portale Deposito Atti Penali' (PDP).

Frequently asked questions

Can the civil party appear in court personally without a lawyer?

No, pursuant to Art. 100(1) c.p.p., the civil party and other private parties (excluding the defendant) must be represented by a lawyer equipped with a 'procura speciale' (special power of attorney).

Is an appointment made via a general power of attorney valid?

Generally no, Art. 100 c.p.p. explicitly requires a 'procura speciale' referring to the specific criminal proceeding in which the party intends to intervene.

What happens if the signature on the power of attorney is not authenticated?

The lack of authentication results in the inadmissibility of the 'atto di costituzione' (appearance document), as the lawyer is not considered to have been validly granted the necessary powers.
