- Reasonable Access. Section 312(a)(7) of the Communications Act and Section 73.1943 of the Commission’s rules require commercial broadcast stations to provide reasonable access to candidates for federal elective office. This means that commercial television and radio stations must allow legally qualified federal candidates to purchase reasonable amounts of broadcast time throughout their campaigns in all dayparts (i.e., in all parts of the broadcast day), including television prime time and radio drive time. The right bestowed upon federal candidates to purchase broadcast time is not absolute. Stations may take into account certain factors in determining whether a request to purchase broadcast time is reasonable. Reasonable access does not extend to state and local candidates, and stations have discretion whether to accept or refuse requests for the purchase of broadcast time by candidates running in state and local elections.
- Equal Opportunities. Section 315(a) of the Communications Act and Section 73.1941 of the Commission’s rules require that if a station allows a legally qualified candidate for any public office to use its facilities (i.e., make a positive identifiable appearance on the air for at least four seconds), it must give equal opportunities to all other candidates for that office to also use the station. Equal opportunities apply to all commercial and non-commercial stations, as well as all legally qualified candidates for public office (federal, state, and local) throughout their campaigns. Stations are prohibited from censoring ads that are paid for or sponsored by legally qualified candidates and their authorized organizations. As a consequence, stations are protected from liability if these ads contain defamatory material. Certain news-related programs are exempt from equal opportunities. Therefore, an appearance by a legally qualified candidate on a bona fide newscast, regularly scheduled bona fide news interview program, certain documentaries, and on–the–spot coverage of a bona fide news event (including debates and political conventions) does not trigger equal opportunities for opposing candidates.
