“ 9. Insofar as the offence under Section 153-A IPC is concerned, it provides for punishment for promoting enmity between different groups on grounds of religion, race, place of birth, residence, language, caste or community or any other ground whatsoever or brings about disharmony or feeling of hatred or ill-will between different religious, racial, linguistic or regional groups or castes or communities. In our opinion only where the written or spoken words have the tendency or intention of creating public disorder or disturbance of law and order or affect public tranquillity, that the law needs to step in to prevent such an activity. The facts and circumstances of this case unmistakably show that there was no disturbance or semblance of disturbance of law and order or of public order or peace and tranquillity in the area from where the appellants were apprehended while raising slogans on account of the activities of the appellants. The intention to cause disorder or incite people to violence is the sine qua non of the offence under Section 153-A IPC and the prosecution has to prove the existence of mens rea in order to succeed. In this case, the prosecution has not been able to establish any mens rea on the part of the appellants, as envisaged by the provisions of Section 153-A IPC, by their raising casually the three slogans a couple of times. The offence under Section 153-A IPC is, therefore, not made out. ”
