To determine whether the disabling provisions cure CIPA's lack of narrow tailoring, we must first determine, as a matter of statutory construction, under what circumstances the disabling provisions permit libraries to disable the software filters. It is unclear to us whether CIPA's disabling provisions permit libraries to disable the filters any time a patron wishes to access speech that is neither obscenity, child pornography, or in the case of a minor patron, material that is harmful to minors. Whether CIPA permits disabling in such instances depends on the meaning of the provisions' reference to "bona fide research or other lawful purpose." On the one hand, the language "to enable access for bona fide research or other lawful purpose" could be interpreted to mean "to enable access to all constitutionally protected material." As a textual matter, this reading of the disabling provisions is plausible. If a patron seeks access to speech that is constitutionally protected, then it is reasonable to conclude that the patron has a "lawful purpose," since the dissemination and receipt of constitutionally protected speech cannot be made unlawful.
Moreover, since a narrower construction of the disabling provision creates more constitutional problems than a construction of the disabling provisions that permits access to all constitutionally protected speech, the broader interpretation is preferable. "[I]f an otherwise acceptable construction of a statute would raise serious constitutional problems, and where an alternative interpretation of the statute is fairly possible, we are obligated to construe the statute to avoid such problems." INS v. St. Cyr, 121 S. Ct. 2271, 2279 (2001) (internal quotation marks and citations omitted). On the other hand, interpreting CIPA's disabling provisions to permit disabling for access to all constitutionally protected speech presents several problems. First, if "other lawful purpose" means "for the purpose of accessing constitutionally protected speech," then this reading renders superfluous CIPA's reference to "bona fide research," which clearly contemplates some purpose beyond simply accessing constitutionally protected speech. In general, "courts should disfavor interpretations of statutes that render language superfluous." Conn. Nat'l Bank v. Germain, 503 U.S. 249, 253 (1992). Furthermore, Congress is clearly capable of explicitly specifying categories of constitutionally unprotected speech, as it did when it drafted CIPA to require funding recipients to use technology protection measures that protect against visual depictions that are "obscene," "child pornography," or, in the case of minors, "harmful to minors." CIPA Sec. 1712(a) (codified at 20 U.S.C. Sec. 9134(f)(1)(A)(i)(I)-(III)); CIPA Sec. 1721(b) (codified at 47 U.S.C. Sec. 254(h)(6)(B)(i)(I)-(III)). If Congress intended CIPA's disabling provisions simply to permit libraries to disable the filters to allow access to speech falling outside of these categories, Congress could have drafted the disabling provisions with greater precision, expressly permitting libraries to disable the filters "to enable access for any material that is not obscene, child pornography, or in the case of minors, harmful to minors," rather than "to enable access for bona fide research or other lawful purposes," which is the language that Congress actually chose.
At bottom, however, we need not definitively construe CIPA's disabling provisions, since it suffices in this case to assume without deciding that the disabling provisions permit libraries to allow a patron access to any speech that is constitutionally protected with respect to that patron. Although this interpretation raises fewer constitutional problems than a narrower interpretation, this interpretation of the disabling provisions nonetheless fails to cure CIPA's lack of narrow tailoring. Even if the disabling provisions permit public libraries to allow patrons to access speech that is constitutionally protected yet erroneously blocked by the software filters, the requirement that library patrons ask a state actor's permission to access disfavored content violates the First Amendment. The Supreme Court has made clear that content-based restrictions that require recipients to identify themselves before being granted access to disfavored speech are subject to no less scrutiny than outright bans on access to such speech. In Lamont v. Postmaster General, 381 U.S. 301 (1965), for example, the Court held that a federal statute requiring the Postmaster General to halt delivery of communist propaganda unless the addressee affirmatively requested the material violated the First Amendment: We rest on the narrow ground that the addressee in order to receive his mail must request in writing that it be delivered. This amounts in our judgment to an unconstitutional abridgment of the addressee's First Amendment rights. The addressee carries an affirmative obligation which we do not think the Government may impose on him. This requirement is almost certain to have a deterrent effect, especially as respects those who have sensitive positions. Id. at 307.
Similarly, in Denver Area Educational Telecommunications Consortium, Inc. v. FCC, 518 U.S. 727 (1996), the Court held unconstitutional a federal law requiring cable operators to allow access to patently offensive, sexually explicit programming only to those subscribers who requested access to the programming in advance and in writing. Id. at 732-33. As in Lamont, the Court in Denver reasoned that this content-based restriction on recipients' access to speech would have an impermissible chilling effect: "[T]he written notice requirement will . . . restrict viewing by subscribers who fear for their reputations should the operator, advertently or inadvertently, disclose the list of those who wish to watch the 'patently offensive' channel." Id. at 754; see also Fabulous Assocs., Inc. v. Pa. Pub. Util. Comm'n, 896 F.2d 780, 785 (3d Cir. 1990) (considering the constitutionality of a state law requiring telephone users who wish to listen to sexually explicit telephone messages to apply for an access code to receive such messages, and invalidating the law on the ground that "[a]n identification requirement exerts an inhibitory effect"). We believe that CIPA's disabling provisions suffer from the same flaws as the restrictions on speech in Lamont, Denver, and Fabulous Associates. By requiring library patrons affirmatively to request permission to access certain speech singled out on the basis of its content, CIPA will deter patrons from requesting that a library disable filters to allow the patron to access speech that is constitutionally protected, yet sensitive in nature. As we explain above, we find that library patrons will be reluctant and hence unlikely to ask permission to access, for example, erroneously blocked Web sites containing information about sexually transmitted diseases, sexual identity, certain medical conditions, and a variety of other topics. As discussed in our findings of fact, software filters block access to a wide range of constitutionally protected speech, including Web sites containing information that individuals are likely to wish to access anonymously.
That library patrons will be deterred from asking permission to access Web sites containing certain kinds of content is evident as a matter of common sense as well as amply borne out by the trial record. Plaintiff Emmalyn Rood, who used the Internet at a public library to research information relating to her sexual identity, testified that she would have been unwilling as a young teen to ask a librarian to disable filtering software so that she could view materials concerning gay and lesbian issues. Similarly, plaintiff Mark Brown stated that he would have been too embarrassed to ask a librarian to disable filtering software if it had impeded his ability to research surgery options for his mother when she was treated for breast cancer. As explained in our findings of fact, see supra at Subsection II.D.2.b, the reluctance of patrons to request permission to access Web sites that were erroneously blocked is further established by the low number of patron unblocking requests, relative to the number of erroneously blocked Web sites, in those public libraries that use software filters and permit patrons to request access to incorrectly blocked Web sites. Cf. Fabulous Assocs., 896 F.2d at 786 ("On the record before us, there is more than enough evidence to support the district court's finding that access codes will chill the exercise of some users' right to hear protected communications."). To be sure, the government demonstrated that it is possible for libraries to permit patrons to request anonymously that a particular Web site be unblocked. In particular, the Tacoma Public Library has configured its computers to present patrons with the option, each time the software filter blocks their access to a Web page, of sending an anonymous email to library staff requesting that the page be unblocked. Moreover, a library staff member periodically scans logs of URLs blocked by the filters, in an effort to identify erroneously blocked sites, which the library will subsequently unblock. Although a public library's ability to permit anonymous unblocking requests addresses the deterrent effect of requiring patrons to identify themselves before gaining access to a particular Web site, we believe that it fails adequately to address the overblocking problem.
In particular, even allowing anonymous requests for unblocking burdens patrons' access to speech, since such requests cannot immediately be acted on. Although the Tacoma Public Library, for example, attempts to review requests for unblocking within 24 hours, requests sometimes are not reviewed for several days. And delays are inevitable in libraries with branches that lack the staff necessary immediately to review patron unblocking requests. Because many Internet users "surf" the Web, visiting hundreds of Web sites in a single session and spending only a short period of time viewing many of the sites, the requirement that a patron take the time to affirmatively request access to a blocked Web site and then wait several days until the site is unblocked will, as a practical matter, impose a significant burden on library patrons' use of the Internet. Indeed, a patron's time spent requesting access to an erroneously blocked Web site and checking to determine whether access was eventually granted is likely to exceed the amount of time the patron would have actually spent viewing the site, had the site not been erroneously blocked. This delay is especially burdensome in view of many libraries' practice of limiting their patrons to a half hour or an hour of Internet use per day, given the scarcity of terminal time in relation to patron demand.
The burden of requiring library patrons to ask permission to view Web sites whose content is disfavored resembles the burden that the Supreme Court found unacceptable in Denver, which invalidated a federal law requiring cable systems operators to block subscribers' access to channels containing sexually explicit programming, unless subscribers requested unblocking in advance. The Court reasoned that "[t]hese restrictions will prevent programmers from broadcasting to viewers who select programs day by day (or, through 'surfing,' minute by minute) . . . ." Denver, 518 U.S. at 754. Similarly, in Fabulous Associates, the Third Circuit explained that a law preventing adults from listening to sexually explicit phone messages unless they applied in advance for access to such messages would burden adults' receipt of constitutionally protected speech, given consumers' tendency to purchase such speech on impulse. See Fabulous Assocs., 896 F.2d at 785 (noting that officers of two companies that sell access to sexually explicit recorded phone messages "testified that it is usually 'impulse callers' who utilize these types of services, and that people will not call if they must apply for an access code"). In sum, in many cases, as we have noted above, library patrons who have been wrongly denied access to a Web site will decline to ask the library to disable the filters so that the patron can access the Web site. Moreover, even if patrons requested unblocking every time a site is erroneously blocked, and even if library staff granted every such request, a public library's use of blocking software would still impermissibly burden patrons' access to speech based on its content. The First Amendment jurisprudence of the Supreme Court and the Third Circuit makes clear that laws imposing content-based burdens on access to speech are no less offensive to the First Amendment than laws imposing content-based prohibitions on speech: It is of no moment that the statute does not impose a complete prohibition. The distinction between laws burdening and laws banning speech is but a matter of degree. The Government's content-based burdens must satisfy the same rigorous scrutiny as its content-based bans. . . . When the purpose and design of a statute is to regulate speech by reason of its content, special consideration or latitude is not afforded to the Government merely because the law can somehow be described as a burden rather than outright suppression.
United States v. Playboy Entm't Group, Inc., 529 U.S. 803, 812, 826 (2000) (invalidating a federal law requiring cable television operators to limit the transmission of sexually explicit programming to the hours between 10:00 p.m. and 6:00 a.m.); see also Fabulous Assocs., 896 F.2d at 785 ("[H]ere . . . there is no outright prohibition of indecent communication. However, the First Amendment protects against government inhibition as well as prohibition.") (internal quotation marks and citation omitted). Even if CIPA's disabling provisions could be perfectly implemented by library staff every time patrons request access to an erroneously blocked Web site, we hold that the content-based burden that the library's use of software filters places on patrons' access to speech suffers from the same constitutional deficiencies as a complete ban on patrons' access to speech that was erroneously blocked by filters, since patrons will often be deterred from asking the library to unblock a site and patron requests cannot be immediately reviewed. We therefore hold that CIPA's disabling provisions fail to cure CIPA's lack of narrow tailoring. 5. Conclusion; Severability
Based upon the foregoing discussion, we hold that a public library's content-based restriction on patrons' access to speech on the Internet is subject to strict scrutiny. Every item in a library's print collection has been selected because library staff, or a party to whom staff delegates the decision, deems the content to be particularly valuable. In contrast, the Internet, as a forum, is open to any member of the public to speak, and hence, even when a library provides filtered Internet access, it creates a public forum in which the vast majority of the speech has been reviewed by neither librarians nor filtering companies. Under public forum doctrine, where the state creates such a forum open to any member of the public to speak on an unlimited number of subjects, the state's decision selectively to exclude certain speech on the basis of its content, is subject to strict scrutiny, since such exclusions risk distorting the marketplace of ideas that the state has created. Application of strict scrutiny to public libraries' content- based restrictions on their patrons' access to the Internet finds further support in the analogy to traditional public fora, such as sidewalks, parks, and squares, in which content-based restrictions on speech are always subject to strict scrutiny. Like these traditional public fora, Internet access in public libraries uniquely promotes First Amendment values, by offering low barriers to entry to speakers and listeners. The content of speech on the Internet is as diverse as human thought, and the extent to which the Internet promotes First Amendment values is evident from the sheer breadth of speech that this new medium enables. To survive strict scrutiny, a public library's use of filtering software must be narrowly tailored to further a compelling state interest, and there must be no less restrictive alternative that could effectively further that interest. We find that, given the crudeness of filtering technology, any technology protection measure mandated by CIPA will necessarily block access to a substantial amount of speech whose suppression serves no legitimate government interest. This lack of narrow tailoring cannot be cured by CIPA's disabling provisions, because patrons will often be deterred from asking the library's permission to access an erroneously blocked Web page, and anonymous requests for unblocking cannot be acted on without delaying the patron's access to the blocked Web page, thereby impermissibly burdening access to speech on the basis of its content.
Moreover, less restrictive alternatives exist to further a public library's legitimate interests in preventing its computers from being used to access obscenity, child pornography, or in the case of minors, material harmful to minors, and in preventing patrons from being unwillingly exposed to patently offensive, sexually explicit speech. Libraries may use a variety of means to monitor their patrons' use of the Internet and impose sanctions on patrons who violate the library's Internet use policy. To protect minors from material harmful to minors, libraries could grant minors unfiltered access only if accompanied by a parent, or upon parental consent, or could require minors to use unfiltered terminals in view of library staff. To prevent patrons from being unwillingly exposed to offensive, sexually explicit content, libraries can offer patrons the option of using blocking software, can place unfiltered terminals outside of patrons' sight lines, and can use privacy screens and recessed monitors. While none of these less restrictive alternatives are perfect, the government has failed to show that they are significantly less effective than filtering software, which itself fails to block access to large amounts of speech that fall within the categories sought to be blocked.
