The Legal Value of PEC in Electronic Filing: Proof of Delivery
6 min read · Updated July 2026 · Editorial oversight: Avv. Federico Papa
The legal value of Certified Email (PEC) in electronic filing has returned to the spotlight following recent interpretative clarifications in Court of Cassation Order No. 11112 of April 23, 2024. According to press reports, tension persists between the technical operations of ministerial systems and mandatory procedural deadlines, creating uncertainty regarding the validity of documents submitted close to the deadline. Through an analysis of the facts and relevant regulations, we will examine how supreme court case law has consolidated the principle of timeliness linked to the second delivery receipt. In this study, we reconstruct the legal background and apply it to a didactic twin case. The goal is to provide practitioners with the tools to distinguish between mere technical warnings and fatal errors, analyzing the possible outcomes of disputes over filing regularity and the best defensive strategies to avoid irreversible forfeitures.

In brief
This analysis addresses the legal value of the Delivery Receipt (RdAC) in the electronic filing of court documents. Based on recent case law from April 2024 (Ordinance No. 11112), the article clarifies why the timeliness of a filing depends exclusively on the second PEC receipt, regardless of the court registry's processing times. Through an examination of the rules and the reconstruction of a didactic twin case, operational guidelines are provided to handle technical errors and system malfunctions, securing the right of defense.
The Fact
According to reports from outlets such as Ipsoa and Diritto.it, the issue stems from a series of appeals reaching the Supreme Court regarding the declaration of lateness for certain electronic filings. Specifically, several lawyers had filed appeal documents on the final deadline day, receiving the Delivery Receipt (RdAC) by 11:59 PM.
However, the courts of merit had considered the filings late because the manual acceptance (the so-called fourth PEC) occurred in the following days, or because the system flagged technical anomalies in the attached files. The procedural stage involved the Supreme Court's intervention to resolve the conflict between the effectiveness of electronic delivery and the rejection power of court registries.

The Regulations at Stake
The central provisions are Article 6 of Presidential Decree No. 68 of February 11, 2005, and Article 16-bis, paragraph 7, of Decree-Law No. 179 of October 18, 2012. The former establishes that the RdAC constitutes certain proof of the message's delivery to the recipient.
The second provision specifies that the filing is considered perfected for the submitter at the moment the delivery receipt is generated by the Ministry of Justice's certified email provider. Finally, Article 147 of the Code of Civil Procedure, post-reform, guarantees that electronic filing can occur until midnight of the last useful day, eliminating the former 9:00 PM limit.
What Case Law Says
Supreme court case law has unambiguously clarified that the completion of the filing for the depositor occurs upon the generation of the delivery receipt. The courts specified that delays in processing by registry staff or internal server malfunctions at the Ministry cannot prejudice the party that timely transmitted the document.
Furthermore, it has been established that only a fatal error, such as making the file entirely unreadable or lacking a digital signature, invalidates the filing, whereas simple warning messages do not justify the rejection of the document.

What It Teaches Professionals
- Always retain the original PEC message files (.eml or .msg formats) for both acceptance and delivery receipts.
- Do not wait passively for the fourth PEC to confirm filing status, but continuously monitor system updates.
- In the event of rejections due to alleged technical flaws, promptly request the judge's intervention to validate the filing or grant relief from forfeiture.
- Avoid submitting filings in the final minutes before midnight to mitigate risks linked to network or server outages.

Frequently asked questions
What happens if the delivery receipt arrives after midnight?
If the RdAC is generated after 11:59 PM on the final day, the filing is considered late. Timeliness depends on the moment of delivery to the recipient's mailbox (second PEC), not the initial dispatch (first PEC of acceptance).
Can one obtain relief from forfeiture for a system failure?
Yes, if the professional proves that the filing failed due to a cause beyond their control, such as a documented outage of the Ministry of Justice servers.
Can the clerk reject a document if the file is a non-native PDF?
Although technical specifications require native PDFs, established case law considers the filing of a scanned document valid provided it is readable and has achieved its procedural purpose.
