“We are to see, if under the concept of the offence, created by the Act, there must be some allegation of any act or omission towards commission of the offence. While taking up the question of constitutional validity of the Act in the case of Ashok Kumar Dixit [Ashok Kumar Dixit v. State of U.P., 1987 ACC 164 : (1987 All LJ 806)], the Full Bench had made certain very important observations which are relevant for the present point. It was observed that a person was not liable to be punished under the Act merely because he happened to be a member of the group. The Court was, rather, of the view that a person could be accused of an offence only if he had chosen to join a group which indulges in anti-social activities, defined under the Act, with use of force for obtaining material or other advantages to himself or to any person. The Court was of the view “The element of actus reus is hence clearly present in the offence created under the statute.” Whenever any act or omission covered by Sections 2 and 3 of the Act is reported an offence is made out and as a corollary it may be indicated without any fear of contradiction that unless an allegation is there concerning an act or omission on the part of an accused, covered by the definition of the term “gang” or “gangster”, no F.I.R. should be maintainable. Whether the allegations are true or false will be a matter for investigation, but unless the allegations of an offence under the Act are indicated, as F.I.R. may not be justifiable whatever large the number of past acts be alleged against him. ”
