Section 294 of the Indian Penal Code

Section 294 of the Indian Penal Code lays down the punishment for obscene acts or words in public. The other sections of Indian Penal code which deal with obscenity are 292 and 293. The law does not clearly define what would constitute an obscene act, but it would enter the domain of the state only when it takes place in a public place to the annoyance of others. Temple art or nakedness of sadhus are traditionally outside the purview of this section.
