LEGAL MEMORANDUM
TO: Atty. Jude Ocampo
FROM: Atty. Ivan Jed T. Rosal
DATE: March 18, 2025
RE: Application of Republic Act 10175 or the Cybercrime Prevention Act of 2012
______________________________________________________________________________
I. ISSUE
Does mere participation in a libelous social media post open oneself to criminal liability under
cyber libel?
II. SHORT ANSWER
No, mere participation in a libelous social media post does not immediately equate to criminal
liability. For one to be held liable through participation, said participation must further propagate
new and libelous material.
III. STATEMENT OF FACTS
Mr. X took to Facebook to air out his grievances against Ms. Y. The former stated in a digital
soliloquy that a certain neighbor of his should run for politics considering she has a “mouth for
luring people albeit into scams”. Mr. X went on to explicitly name said neighbor as Ms. Y. He
further described her as a “woman gifted with a siren’s call but cursed with a basilisk’s face”. To
serve as the coup de grâce to his social media monologue, he confidently stated that Ms. Y had
scammed more than (10) ten different people out of their hard-earned money in a networking
scheme. Ms. A clicked the “love reaction” because she was happy to see someone speaking out
against Ms. Y. Ms. B commented that she was already aware of her devious character and even
stated that Ms. Y also maintains an extramarital affair with a priest. Ms. C shared the post with the
caption “This is terrible!”.
IV. DISCUSSION
A social media post containing defamatory statements toward an individual can be the basis for a
cyber libel case. However, as a general rule, only the original author is liable for said post. Other
people can react or comment their response to said social media post without being subjected to
the same liability as the author. As an exception, subsequent shares or comments that further
propagate the defamatory content could still expose individuals to liability under certain
circumstances.
Republic Act 10175 or the Cybercrime Prevention Act of 2012 uses the Revised Penal Code as the
basis for cyber libel. 1 The Revised Penal Code states that only the author, editor, or business
manager of the publication of the libelous content can be held liable:
“Art. 360. Persons responsible. — Any person who shall publish, exhibit, or cause the publication
or exhibition of any defamation in writing or by similar means, shall be responsible for the same.” 2
The editor or business manager shares the same criminal liability as the author for the defamations
found in any print media. Hence, the crime of cyber libel expressly punishes (2) two sets of
persons:
1. The author of the libelous post, which includes the person who shall publish, exhibit, or
cause the publication of the libelous post. The person who created the libelous post would
fall under this category.
2. The editor or business manager, in case the libelous post is contained in a book, pamphlet,
newspaper, magazine or serial publication.
A person who participates in a libelous post by merely commenting or sharing falls on neither of
the (2) two categories that would incur criminal liability. In the case of Disini, et al., vs Secretary
of Justice, G.R. No. 203335, 11 February 2024, a person giving general comments does not in any
way share the same criminal intent as the author of the post he/she commented on. In fact, the
Supreme Court itself stated that comments such as “I agree” “That’s so true” or “He is really bad”
are “essentially knee-jerk sentiment of the reader who may think little or haphazardly of their
response to the original posting”. 3
The Latin legal principle of “Nullum crimen, nulla poena sine lege" 4 applies in this situation
wherein there is no crime if there is no law punishing it. Nowhere in both the Revised Penal Code
and the Cybercrime Prevention Act does it expressly state that people who comment, react, or
share libelous social media posts incur criminal liability.
Now, before you think this rule is set in stone, let’s talk about the fine print. Jurisprudence dictates
that the rule would inevitably have its own exceptions. The exception arises when the comment is
no longer limited to the context of the original defamatory post. When such a comment goes
1 Republic Act No. 10175, § 4(c)(4) (2012).
2 Revised Penal Code, Art. 360.
3 Disini v. Secretary of Justice, G.R. No. 203335, Feb. 11, 2024.
4 A fundamental principle in criminal law, meaning "No crime, no punishment without law." This ensures that
no one can be punished for an act that is not explicitly criminalized.
beyond the post by offering new libelous content or material, the comment then becomes an
original post, which in turn transforms the person commenting into another offer of a completely
distinct and new defamatory post. This, in effect, accords to the person commenting an entirely
different criminal liability from the previous author.
In the case of Disini, et al., vs Secretary of Justice, G.R. No. 203335, 11 February 2024, the
Supreme Court gave a hypothetical example wherein a person named Nestor posts in his blog
“Armand is a thief!”. On the other hand, another person, Arthur notices the post and comments
“Correct!”. Based on the example, only Nestor can be held liable. His criminal liability is
straightforward wherein he is the author of the post. As for Arthur, not only is he not the author,
but he is also merely expressing his agreement with the blog. The same concepts may be expanded
toward cyber libel, such that, only Nestor would be liable for cyber libel and a million other
“Arthurs” that express mere agreement with that statement would not be subject to liability. 5
V. CONCLUSION
Based on the foregoing discussion, Ms. A and Ms. C do not incur criminal liability for cyber
libel under Republic Act No. 10175. Their respective actions—reacting to and sharing the post—
fall under mere participation, which does not meet the legal definition of authorship or editorial
responsibility for libelous content. Jurisprudence supports that such knee-jerk reactions or
passive engagements do not equate to the publication or propagation of new defamatory material.
However, Ms. B’s comment goes beyond mere agreement and instead introduces a separate
defamatory imputation against Ms. Y. By alleging that Ms. Y maintains an extramarital affair
with a priest, Ms. B essentially became an original author of new libelous material, thereby
exposing herself to criminal liability.
Accordingly, while not all participation in a defamatory social media post results in liability,
individuals must exercise caution when engaging in online discourse. Any comment that expands
or introduces new defamatory imputations may transform a mere participant into an author of
cyber libel, potentially leading to legal consequences.
