If so how?
I read 310 KUHP laws in Indonesia and it says that public interest is a defense. It doesn't list truth as defense.
Some says that if we have evidences, that is defense. What kind of evidences are good enough defenses?
Relying on this version, proof of truth is only allowed in order to establish a "public interest" defense or for a "necessary defense"; but also "if an official is charged with the commission of an act in the exercise of his office". Good luck with "necessary defense". It is not a defense to say "But what I said is true". However, if the defamed person has been convicted in court of said act (the defamatory statement) then there can be no punishment.
