Section 4
SEC. 4. The grantee shall not require any previous censorship of any speech, play, act or scene or other matter to be broadcast and/or telecast from its stations; but if any such speech, play, act or scene or other matter should constitute a violation of the law or infringement of a private right, the grantee shall be free from any liability, civil or criminal, for such speech, play, act or scene or other matter: Provided, That the grantee, during any broadcast and/or telecast, shall cut off from the air the speech, play, act or scene or other matter being broadcast and/or telecast if the tendency thereof is to propose and/or incite treason, rebellion or sedition, or the language used therein or the theme thereof is indecent or immoral, and willful failure to do so shall constitute a valid cause for the suspension of the operation of said station not to exceed six months.
