The crime of libel in the Philippines is defined and penalized under Article 353 (“Definition of Libel”), in relation to Article 355 (“Libel by means of writings or similar means”) of the Revised Penal Code (“RPC”). There was a debate whether the required “publication” in libel encompasses the internet, which was not yet in existence when the RPC was enacted. This debate has been laid to rest, with the enactment of Republic Act (“R.A.”) No. 10175, also known as the Cybercrime Prevention Act of 2012. This article discusses the definition, elements/requisites and applicable penalties for online libel.
