Cyber libel is defined under Section 4(c)(4) of RA 10175, in relation to Article 355 of the Revised Penal Code. It applies to libel committed through a computer system or any other similar means that may be devised in the future. In practice, this covers defamatory statements made on:

• Social media (Facebook, Twitter/X, Instagram)
• Blogs, forums, and comment sections
• Messaging apps (if published to a group or public channel)
• Email (if sent to multiple recipients or published)
• Video platforms like YouTube and TikTok

The key differences include:

Penalty

Cyber libel carries a higher penalty than traditional libel. It is punishable by prision correccional in its maximum period to prision mayor in its minimum period (6 years and 1 day to 12 years), or a fine, or both.

Prescription Period

The Supreme Court has ruled that the prescription period for cyber libel is 12 years (under Act 3326), unlike traditional libel which prescribes in 1 year. This means a complaint can be filed much longer after the online publication.

Publication

Any online post that can be accessed by a third person is considered “published” for libel purposes. This includes private messages sent to a group chat, comments on a public post, and shared content.

Common defenses include:

• Truth — If the statement is true and made with good motives and for justifiable ends, it is a valid defense.
• Privileged communication — Statements made in certain contexts (like judicial proceedings, legislative debates, or official communications) are privileged.
• Fair comment — Opinions about public figures or matters of public interest, when made without malice, may be protected.
• Lack of malice — If the statement was made without malice or ill intent, the case may be defensible.
