Freedom of Speech (Article 19) vs Defamation Laws

Article 19 guarantees freedom of speech, but subject to 'reasonable restrictions' imposed by law in relation to defamation. However, if your statement is true and for public interest, it is a valid defense. Criminal defamation under Section 499/500 PPC and civil suits under the Defamation Ordinance 2002 cannot succeed if the claims are factual.
