Any person who exhibits or permits to exhibit interpolated film is responsible. It has to be observed whether the characters involved in the main film are also involved in the interpolated bits. If it is so, then one can infer that the producer and the distributor may also be responsible for interpolation. According to Section 7(b) of the Act, if any person, without lawful authority, alters or tampers with in any film, after it has been certified, will be committing a crime under Cinematograph Act. It is to be noted that the burden of proving the lawfulness of the act shall lie on the person who altered or tampered with the certified film.
