The Freedom to Read Foundation  yesterday joined with several other library, education, and free speech organizations in filing anamicusbrief with the Ninth Circuit Court of Appeals inArce v. Huppenthal, a lawsuit challenging the constitutionality of Arizona Revised Statute § 15-112(A). The brief argues that the statute, which led to the disbanding of Tucson’s Mexican American Studies (MAS) program, violates Arizona students’ First Amendment rights to receive information and is unconstitutionally overbroad.
