Supreme Court and PEC Notification: Missing Conformity Certificate Is Not Non-Existence

1. The facts

   The case stems from a civil dispute that reached the Supreme Court after an objection of inadmissibility of an appeal was raised in the lower courts. According to reports in specialized outlets such as Cassazione.net and Il Sole 24 Ore, the core issue concerned a PEC notification performed by a lawyer who attached a digital copy of a document (a judgment or a notice of execution) without including the required certificate of conformity to the original, neither in the notification report nor as a separate digitally signed file.

   The applicant argued that such an omission rendered the notification legally non-existent, thereby preventing the running of statutory deadlines or invalidating the title. The matter was referred to the United Sections to clarify whether strict compliance with the technical specifications of the PCT (Digital Civil Process) constitutes a requirement for the existence of the act, or whether its absence can be cured if the recipient has nonetheless received a legible file corresponding in content to the original.

   The rules at play

   1. Article 3-bis of Law no. 53/1994 requires lawyers notifying via PEC to certify the conformity of digital copies to the originals, guaranteeing the public faith of the transmitted document.
   2. Article 16-undecies of Decree-Law no. 179/2012 establishes the technical procedures for executing such certification, allowing it to be included within the notification report or in a separate digital document.
   3. Article 156 of the Code of Civil Procedure sets forth the principle of achievement of purpose, providing that nullity cannot be declared if the act has nonetheless enabled the recipient to exercise their right of defense.

3. What the jurisprudence says

   The Supreme Court case law has consolidated a substance-over-form approach, culminating in the 2024 United Sections ruling. The Court clarified that the certificate of conformity is not an indispensable structural element of notification, but rather a protective guarantee. Consequently, its absence does not give rise to non-existence, which occurs only when the minimum requirements for recognizing the act in the legal system are missing, but rather to a remediable nullity.

   Under the principle of instrumentality of forms, if the notification reached the recipient's PEC mailbox and the recipient was able to open the attachment and understand its content, the purpose of the act is achieved. The nullity remains actionable only if the recipient demonstrates that the omission caused absolute uncertainty regarding the content or a concrete prejudice to the right of defense, a mere formal objection to the defect being insufficient.

8. What it teaches professionals

   1. Drafting diligence: counsel must always include the certificate of conformity as a prudential measure to avoid dilatory objections and potential professional liability.
   2. Burden of proof: for the recipient of a defective document, it is no longer sufficient to raise a formal objection; rather, one must plead and prove a material discrepancy between the copy received and the original.
   3. Effects of appearance: before pleading nullity, counsel must consider that undertaking defensive measures (such as appearing in court) may trigger the automatic cure of the defect through achievement of purpose.
