When Does the One-Year Cyber Libel Period Begin?
Introduction
Online defamation complaints raise a recurring procedural question: when does the one-year prescriptive period for cyber libel begin to run? The answer affects whether a criminal complaint may still be filed, particularly when the allegedly defamatory post was published long before the offended party became aware of it.
The Supreme Court has clarified that cyber libel is not an entirely new crime distinct from libel under the Revised Penal Code. It is libel committed through a computer system, with the use of information and communications technology increasing the applicable penalty. The prescriptive period is therefore governed by the Revised Penal Code, and the period generally runs from discovery—not automatically from the date of online publication.
What Is Cyber Libel?
Libel consists of a public and malicious imputation of a crime, vice, defect, act, omission, condition, status, or circumstance tending to cause the dishonor, discredit, or contempt of a natural or juridical person, or to blacken the memory of a deceased person. This definition appears in Article 353 of the Revised Penal Code.
Section 4(c)(4) of the Cybercrime Prevention Act of 2012 refers to libel as defined under Article 355 of the Revised Penal Code when committed through a computer system or similar future technology. The Supreme Court explained that this provision does not create a wholly separate offense. It applies the existing law on libel to defamatory material published online and imposes a penalty one degree higher under the circumstances recognized by the statute. (“Causing v. People of the Philippines, et al.”, G.R. No. 258524, October 11, 2023) [Causing v. People (2023)](#J1.14)
What Is the Prescriptive Period for Cyber Libel?
Cyber libel prescribes in one year. The Supreme Court held that paragraph 4 of Article 90 of the Revised Penal Code governs because it expressly covers “the crime of libel or other similar offenses.” The Court rejected the view that the heavier penalty for cyber libel places the offense under the longer prescriptive period for crimes punishable by an afflictive penalty. (“Causing v. People of the Philippines, et al.”, G.R. No. 258524, October 11, 2023) [Causing v. People (2023)](#J1.24)
Republic Act No. 4661 shortened the prescriptive period for libel and similar offenses to one year. The same law provides a six-month period for oral defamation and slander by deed. These periods must be distinguished from the civil action for defamation, which is generally subject to a separate one-year period under Article 1147 of the Civil Code.
When Does the One-Year Period Start?
The one-year period for cyber libel begins on the date the offense is discovered by the offended party, the authorities, or their agents. It does not necessarily begin on the date the defamatory post was uploaded or published.
Article 91 of the Revised Penal Code provides that the period of prescription commences from the day the crime is discovered by the offended party, the authorities, or their agents. Applying this provision, the Supreme Court ruled that online publication does not create an automatic presumption that the offended party immediately read or discovered the post. (“Causing v. People of the Philippines, et al.”, G.R. No. 258524, October 11, 2023) [Causing v. People (2023)](#J2.47)
Publication Date Versus Discovery Date
The distinction may be summarized as follows:
| Possible Date | Legal Significance |
|---|---|
| Date of online publication | This is the date when the defamatory material was uploaded or made available, but it is not automatically the starting point for criminal prescription. |
| Date of discovery by the offended party | This may begin the one-year period when the offended party is the person who first discovered the alleged cyber libel. |
| Date of discovery by authorities or their agents | This may begin the period when the authorities or their agents discovered the offense before the offended party did. |
| Date of filing | The complaint must be filed before the applicable one-year period expires, subject to the governing rules on interruption and other procedural circumstances. |
Why the Heavier Cybercrime Penalty Does Not Create a Longer Period
Section 6 of the Cybercrime Prevention Act provides a penalty one degree higher when crimes under the Revised Penal Code or special laws are committed through information and communications technology. The increased penalty does not, by itself, transform cyber libel into a different crime for purposes of prescription.
The Supreme Court reasoned that Section 4(c)(4) of the Cybercrime Prevention Act expressly refers to libel under the Revised Penal Code. Cyber libel remains libel in substance; the computer system is the means by which the defamatory material is published, while the statute provides the corresponding penalty adjustment. (“Causing v. People of the Philippines, et al.”, G.R. No. 258524, October 11, 2023) [Causing v. People (2023)](#J1.17)
The Court also emphasized that prescription statutes must be construed in favor of the accused when competing provisions create uncertainty. The shorter one-year period under Article 90, paragraph 4, therefore prevails over a possible longer period that might otherwise be derived from the penalty imposed for cyber libel. (“Causing v. People”, G.R. No. 258524, 2026) [Causing v. People (2026)](#J2.46)
Effect of the Causing Decision
The Supreme Court abandoned the earlier view that cyber libel prescribes in 15 years under the provision applicable to offenses punishable by an afflictive penalty. The controlling rule is that cyber libel prescribes in one year under Article 90, paragraph 4 of the Revised Penal Code.
The decision is significant because it identifies both the applicable period and the proper reckoning point: one year from discovery of the offense by the offended party, the authorities, or their agents. The date of publication remains relevant evidence, but it does not automatically control the commencement of prescription.
How the Rule Applies in Common Situations
If a defamatory post was uploaded on January 1 but the offended party discovered it only on April 1, the one-year period generally begins on April 1, assuming the post was not earlier discovered by the authorities or their agents.
If the offended party discovered the post on April 1, but an investigating authority had already discovered it on March 1, the earlier discovery by the authority may become material in determining when prescription began.
If the offended party merely alleges a late discovery without supporting details, the timing of discovery may become a factual issue. Evidence such as screenshots, messages forwarding the post, digital notifications, affidavits, and the chronology of communications may help establish when the post was actually brought to the offended party’s attention.
Evidence Relevant to the Reckoning Date
Parties should preserve evidence showing both the date of publication and the date of discovery. These dates are not necessarily the same and should be pleaded and proved separately.
- screenshots showing the post, account, and available publication information;
- messages or emails transmitting the post to the offended party;
- affidavits identifying who first saw or reported the material;
- records of requests made to platforms or investigators; and
- the complaint-affidavit and attachments showing the chronology of discovery.
Evidence should be preserved in its original form whenever possible. Copies should identify the source, date obtained, person who preserved the material, and any relevant account or message information.
Issues Counsel Should Examine Before Filing
Counsel should first identify the exact defamatory publication and determine whether it satisfies the elements of libel under Articles 353 and 355 of the Revised Penal Code. The analysis should also consider publication, identifiability of the offended person, malice, and any applicable privileged communication or fair-report defense.
The prescription analysis should then establish the earliest legally relevant discovery date. It is not enough to count one year backward from the intended filing date; the record should explain when the offended party, authorities, or their agents first discovered the alleged offense.
Counsel should also distinguish criminal cyber libel from a civil action for damages arising from defamation. The criminal prescription rule and the civil prescriptive period do not automatically operate in the same manner.
Final Observations
The controlling rule is straightforward: cyber libel prescribes in one year, and the period begins upon discovery by the offended party, the authorities, or their agents. Online publication alone does not conclusively establish the starting date.
Anyone considering a cyber libel complaint should promptly preserve the digital evidence, document the date of actual discovery, identify any earlier discovery by authorities or their agents, and file within the applicable period. Because prescription may depend on disputed facts, the complaint should present a clear and supported chronology rather than merely stating the date when the post was uploaded.
