Checklist: what to check before filing the supplementary brief under art. 171-ter c.p.c.

2 min read · Editorial oversight: Avv. Federico Papa

This operational checklist is used to verify the correctness of the supplementary brief after drafting and before electronic filing. The legal professional must check each item to avoid procedural forfeitures or evidentiary preclusions resulting from formal or calculation errors.

In brief

Reviewing supplementary briefs under Art. 171-ter c.p.c. requires checking backward deadlines, which expire on the preceding business day if falling on a Saturday or holiday. Electronic filing via PCT requires digital signatures and compliance with Art. 121 c.p.c. regarding conciseness. The first brief permits emendatio libelli or reconventio reconventionis. The second brief must include all evidentiary requests to avoid preclusion under Art. 153 c.p.c. The third brief is restricted to rebuttal evidence and refutatory documents. Specific responses to judicial directions under Art. 171-bis c.p.c. are mandatory.

1.
Verification of backward deadline calculation
Verify the deadlines under art. 171-ter c.p.c., keeping in mind that if the deadline falls on a Saturday or a holiday, it is moved to the preceding business day. Failure to comply with this rule results in the brief being inadmissible due to late filing.

2.
Response to judicial directions under art. 171-bis
Ensure that you have taken a specific and detailed position on every direction or remark made by the judge in the decree issued under art. 171-bis c.p.c. Failure to respond to these remarks may result in serious defensive preclusions for the party.
3.
Distinction between emendatio and reconventio reconventionis
Ensure that in the first brief, amendments (emendatio) or new claims (reconventio reconventionis) are included only if they arise directly from the counterclaim or defenses raised by the defendant or third party. Outside of these cases, introducing new claims is inadmissible.
4.
Content limits of the third brief
Check that the third brief is strictly limited to rebuttal evidence in response to the opposing parties' requests. Filing new documents is permitted only to refute the adverse party's direct evidence, whereas submitting new requests for direct evidence is inadmissible.

5.
Compliance with formal requirements and conciseness
Check that the document complies with the criteria of clarity and conciseness set out in art. 121 c.p.c., ensuring that its content is suited to achieving its procedural purpose without unduly burdening the trial.
6.
Completeness of evidentiary requests
Verify that all documentary evidence and requests for oral evidence have been fully included in the second brief. Omitting a request at this stage precludes submitting it later, except in cases of relief from forfeiture under art. 153 c.p.c.
7.
Accuracy of identification data
Check the heading, the general docket number, and the names of the parties throughout the document. Errors in identification data can cause issues when uploading to the correct electronic court file.
8.
Presence of digital signature
Verify that the file has been digitally signed before final submission through the electronic civil trial system. The lack of a signature may render the document legally void.

Frequently asked questions

What happens if the deadline for the supplementary brief expires on a Saturday?

Since it is a backward deadline, the expiration is moved to the preceding business day (e.g., Friday) to avoid late filing.

Is it possible to produce new documents with the third supplementary brief?

Yes, but exclusively for the purpose of submitting rebuttal evidence. Pursuant to art. 171-ter, n. 3, c.p.c., parties may produce documents aimed solely at refuting the adverse party's direct evidence.
