Harmful to minors

Some of the terms mentioned in this act, such as “inappropriate matter” and what is “harmful to minors”, are explained in the law. Under the Neighborhood Act (47 U.S.C. § 254(l)(2) as added by CIPA sec. 1732), the definition of “inappropriate matter” is locally determined:

Local Determination of Content – a determination regarding what matter is inappropriate for minors shall be made by the school board, local educational agency, library, or other United States authority responsible for making the determination. No agency or instrumentality of the Government may – (a) establish criteria for making such determination; (b) review agency determination made by the certifying school, school board, local educational agency, library, or other authority; or (c) consider the criteria employed by the certifying school, school board, educational agency, library, or other authority in the administration of subsection 47 U.S.C. § 254(h)(1)(B).

The CIPA defines “harmful to minors” as:

Any picture, image, graphic image file, or other visual depiction that – (i) taken as a whole and with respect to minors, appeals to a prurient interest in nudity, sex, or excretion; (ii) depicts, describes, or represents, in a patently offensive way with respect to what is suitable for minors, an actual or simulated sexual act or sexual contact, actual or simulated normal or perverted sexual acts, or a lewd exhibition of the genitals; and (iii) taken as a whole, lacks serious literary, artistic, political, or scientific value as to minors” (Secs. 1703(b)(2), 20 U.S.C. sec 3601(a)(5)(F) as added by CIPA sec 1711, 20 U.S.C. sec 9134(b)(f )(7)(B) as added by CIPA sec 1712(a), and 147 U.S.C. sec. 254(h)(c)(G) as added by CIPA sec. 1721(a)).
