Sign Regulation and Free Speech: Spooking the DoppelgangerSession: Making Sign Ordinances WorkApril 14, 10:15 AM
No area of land use law is more difficult than sign regulation. The difficulties arise from free speech law and how it affects the regulation of signs and the messages they contain. Bedeviled by a Supreme Court decision described as a "Tower of Babel,"(1) municipalities(2) must struggle to regulate signs without provoking free speech objections.(3) This article examines this constitutional thicket to make sense of free speech doctrines that shape sign regulation. It first considers the rules courts apply when they review sign regulations for free speech violations. It then examines three problems in sign control that are especially contentious. These are the justification municipalities must have for regulating the aesthetics of signage, the content neutrality issue, and the problems that arise in regulating off-premise signs, often called billboards. I. SETTING THE STAGE: FREE SPEECH PRINCIPLESSign regulation historically triggered objections that it is facially unconstitutional because aesthetic judgments are subjective. This argument is essentially a substantive due process objection that the aesthetic purposes of sign regulation are not legitimate. However, most state courts reject it by holding that "aesthetics alone" is a proper basis for land use regulation.(4) They also apply a presumption of constitutionality to sign regulation, as they do to all municipal regulation of economic interests. The presumption means a regulation is constitutional if it has a reasonable basis. For example, state courts apply the presumption to uphold regulations that govern the time, place and manner of sign display.(5) This state law background is critical, because the judicial landscape changes when courts apply the free speech clause of the federal constitution.(6) They reverse the usual presumption of constitutionality, but the depth of the reversal depends on the type of speech affected.(7) One critical distinction is between commercial and noncommercial speech. In sign regulation, a message on a sign that promotes commercial products or services is commercial speech. All other messages are noncommercial, such as a message that has ideological or political content. Examples are signs that say "Abortion is Evil" or "Elect Grimsted to Congress." Commercial and noncommercial speech enjoy different levels of constitutional protection. The courts apply a less demanding test to laws that affect commercial speech, including sign regulations, than they apply to regulations that affect noncommercial speech. The landmark Supreme Court case on laws affecting commercial speech is Central Hudson Gas & Electric Co. v. Public Service Commission.(8) There the Court held that a regulation of commercial speech must meet a three-part test. If the speech concerns lawful activity and is not false or misleading, then it must (1) serve a substantial governmental interest, (2) directly advance the asserted governmental interest, and (3) be no more extensive than necessary to serve that interest.(9) Rumblings in the Supreme Court may suggest it may be willing to reconsider and perhaps tighten the judicial review standards adopted by Central Hudson,(10) but until it does so that case still controls. The leading Supreme Court case that applied free speech principles to sign ordinances is Metromedia, Inc. v. City of San Diego,(11) the case described as a Tower of Babel. There a badly divided Court approved a ban on billboards contained in the citys comprehensive sign ordinance, but held it unconstitutional because it also contained provisions found to violate the free speech clause. The opinion that attracted the most support was a plurality opinion signed by four Justices, none of whom are still on the Court. Nevertheless, with some exceptions,(12) most courts continue to follow the free speech principles laid down in the plurality opinion.(13) Because the Metromedia plurality opinion has become so decisive, the discussion that follows relies on it as the basis for examining the free speech issues presented by sign regulation. II. SOME COMMON SIGN REGULATION PROBLEMSA. Regulating AestheticsRecall that Central Hudson requires municipalities to show that a regulation affecting commercial speech will serve a substantial governmental interest. Traffic safety and aesthetics are the two governmental interests municipalities usually assert, and the Metromedia plurality opinion approved both as a basis for upholding the citys ordinance. It seemed to accept traffic safety as a per se justification, noting the California Supreme Court held as a matter of law that an ordinance prohibiting billboards "designed to be viewed from streets and highways reasonably relates to traffic safety."(14) The plurality agreed, holding it would "likewise hesitate to disagree with the accumulated, common-sense judgments of local lawmakers" and many courts that billboards "are real and substantial hazards to traffic safety."(15) This holding is helpful when sign regulation prohibits signs visible from highways or improves traffic safety by restricting their size, height and spacing. Sign regulation deals with much more, however, and requires an aesthetic basis when traffic safety issues do not dominate. The California Supreme Court accepted aesthetics alone as a sufficient basis for upholding the San Diego ordinance, though it also noted that the aesthetic and economic justifications for the ordinance were identical because the state relied on its scenery to attract traffic and commerce.(16) The Metromedia plurality went further, holding it was not "speculative to recognize that billboards, by their very nature, wherever located and however constructed, can be perceived as an esthetic harm."(17) The Supreme Court later confirmed its holding that aesthetic interests justify sign regulation under the free speech clause by upholding an ordinance prohibiting the posting of signs on public property that prohibited political signs.(18) These decisions are a strong endorsement of aesthetics as a substantial governmental purpose that satisfies the free speech clause, but some important questions remain unanswered. Metromedia came up on a summary judgment motion, in a case where the parties stipulated facts that did not question the citys conclusion about aesthetic impacts. This history encourages sign companies to argue the Metromedia plurality did not consider what a municipality has to show to justify a sign ordinance when there is no such stipulation. When a sign company challenges a sign ordinance in court it may argue a municipality must show that its ordinance accomplishes an aesthetic purpose as applied to its signs. This argument would make it difficult to defend sign regulations because any one companys signs are not likely to have a significant effect on the aesthetics of a community.(19) The Supreme Court has not accepted the argument that individualized proof of a laws aesthetic effect is required in commercial speech cases. In a case upholding a federal statute prohibiting radio stations in non-lottery states from broadcasting lottery advertising, it concluded an individualistic, as-applied analysis of the statutes effect on a particular radio station was inappropriate under Central Hudson. Instead, the validity of a regulation depends on "the overall problem the government seeks to correct."(20) The sign cases have followed this decision, holding that courts should test sign regulations by their effect on a broad category of speech, not by their effect on an individual plaintiffs signs.(21) These cases mean municipalities need only identify broad categories of signs whose aesthetic problems require regulation,(22) such as billboards.(23) B. Viewpoint and Content Neutrality1. The Supreme Court CasesLaws must have a neutral effect on speech.(24) The typical sign ordinance is a time, place and manner regulation that does not present a neutrality problem.(25) A time, place and manner regulation is a law that regulates activities to protect governmental interests unrelated to speech. An example is an ordinance that contains limitations on the size, number and height of signs. Because they have a neutral effect on speech, time, place and manner regulations are usually constitutional under the free speech clause.(26) There are two types of neutrality: viewpoint neutrality and content neutrality. Viewpoint neutrality means a sign regulation may not regulate a point of view. An example is a sign ordinance that prohibits any sign containing a message that opposes abortion. This kind of ordinance is not viewpoint-neutral and clearly violates the free speech clause.(27) Content neutrality creates more difficult problems. Content neutrality means a sign regulation may not define the content of a sign. A sign ordinance that prohibits any sign that contains any message of any kind on abortion is an example. As a leading Supreme Court case put it, the "principal inquiry" in deciding content neutrality is "whether the government has adopted a regulation because of a disagreement with the message it conveys. The governments purpose is the controlling consideration."(28) Any law that regulates content must satisfy a strict scrutiny test that requires narrow tailoring to meet a compelling governmental interest.(29) This test is more demanding than the Central Hudson that governs commercial speech. Neither may a law make distinctions based on content. A content neutrality problem arose in Metromedia. Like many sign ordinances, the San Diego ordinance included a list of exempt signs defined by their content, such as signs that identified a property and its owner.(30) The plurality struck down all of these exemptions as content-based because it held the exemptions discriminated between different types of signs because of their content.(31) Despite the Metromedia plurality opinion, the Supreme Court has not always applied the content neutrality rule to sign regulation. It appeared to require only viewpoint neutrality in a later case upholding an ordinance prohibiting the posting of signs on public property.(32) Then, in City of Ladue v. Gilleo,(33) the court held a sign ordinance violated free speech without relying on the content neutrality rule, although it clearly could have applied. The Court held invalid an ordinance that prohibited homeowner signs in residential areas with only a few exceptions, such as safety hazard signs. Gilleo posted a war protest sign in her window, and the city required its removal. The Court agreed that municipalities have a valid interest in reducing visual clutter, but held they cannot do so by foreclosing an important and distinct medium of expression for political, religious or personal messages. The Court noted it had always had a special respect for individual liberty in the home and a persons ability to speak there. Justice OConnor, concurring, complained that the Court should have decided the case by holding that the ordinance was not content-neutral.(34) The status of the content neutrality requirement in sign regulation is also uncertain because of the judicial response in lower courts to the invalidation of the content-based exemptions by the Metromedia plurality. Some courts have followed the Metromedia plurality holding on this problem,(35) but some have not.(36) Whether sign regulations must be both viewpoint-neutral and content-neutral has a critical impact on their constitutionality. Viewpoint neutrality is not a serious problem. No municipality is likely to adopt a sign ordinance, for example, which prohibits signs advocating the saving of whales. Content neutrality is more difficult. Municipalities have typically defined signs by their content because this makes sense. A directional sign, for example, is a sign that gives directions. Content neutrality means that this kind of definition is not constitutional. 2. The Regulatory RiskAlthough the status of the content neutrality rule may not be entirely clear, its endorsement by the Metromedia plurality cautions that content neutrality is a problem in sign regulation. Content neutrality has an impact on sign regulation because disagreement with a message, as the Supreme Court put it, is not the only basis for finding a law content-based. The Metromedia plurality made it clear that content neutrality prohibits benign regulations that define signs by their message, though it did not discuss the implications of this holding.(37) It did so, as noted earlier, by striking down perfectly innocent sections in the San Diego ordinance that exempted several signs that could contain various messages. The plurality holding on content-based exemptions, if still good law, makes it impossible to define signs by the messages they can display.(38) A federal district court case,(39) illustrates the risks municipalities take when they define signs by their content, and then use these content-based definitions as the basis for their regulations. The ordinance in this case took this approach, and the court angrily struck it down. As a result, municipalities cannot authorize signs that are commonly used and that can be visually attractive additions to the urban landscape. Time and temperature signs are one example. Banks and other financial institutions often display them, and they are quite attractive when displayed in clocks in public squares. Nevertheless, a sign ordinance specifically authorizing the display of time and temperature signs risks invalidation as content-based.(40) This review of content neutrality problems suggests, at the least, that municipalities must look carefully at their sign definitions. If they do so they will find they can make marginal changes in definitions that can achieve aesthetic purposes without violating the free speech clause. For example, an ordinance can regulate time and temperature and similar signs by defining "changeable copy" as "copy that changes at intervals of more than once every six seconds."(41) The ordinance can then authorize signs with changeable copy and specify where these signs can and cannot locate. This is a time, place and manner regulation that regulates time and temperature and any other moving sign without creating content neutrality problems. 3. Standing and SeverabilityThe content neutrality problem and its threat to sign regulation is aggravated by the rules governing standing in free speech cases, and the rules governing the severability of unconstitutional sections in sign ordinances. These rules make it essential to review every requirement in a sign ordinance for free speech problems. Municipalities may believe that benign provisions in sign ordinances, such as time and temperature provisions, are not vulnerable. They may believe that the billboard companies who are their most likely antagonists cannot attack them, and that businesses benefitted by them will not object. They should think twice. Usually, of course, a party may only assert constitutional violations of its own rights. The rule is different in free speech cases. In these cases the courts permit facial challenges to legislation if it unconstitutionally regulates protected speech though the plaintiffs speech is not protected.(42) Examples are a sign regulation that "chills" the First Amendment rights of others not before the court, and a sign regulation claimed to be invalid because it regulates content. These standing rules mean a billboard company can challenge a provision authorizing time and temperature signs by claiming it is content-based though it is not affected by it. The facial vulnerability of a sign ordinance makes it more likely a court will hold it nonseverable. A court can invalidate an ordinance if it holds some of its sections unconstitutional if it believes the municipality would not have enacted what remains, and if the remainder of the ordinance cannot stand independently.(43) This risk is aggravated when plaintiffs can facially attack sections in sign regulations claimed to violate free speech law, even though they do not affect them. An ordinance is more difficult to sever if a court holds several of its sections unconstitutional. Municipalities can attempt to encourage severability by including a clause stating a legislative intent that the remainder of an ordinance is constitutional if a court invalidates one or more sections. The difficulty is that courts may reject this statement of intent in sign cases because sign ordinances usually are highly interdependent. Severability then becomes difficult when a court holds that one or more sections violate the free speech clause, as the cases show.(44) The risk that a court will reject severability increases the stakes in sign ordinance litigation, because a municipality runs the risk it will lose the entire ordinance if a court strikes down even one section. This risk is all the more uncertain because severability is fact-intensive, and it is difficult to predict how any court will rule on this question. C. Off-Premise vs. On-Premise Signs1. The Metromedia Plurality DecisionThe distinction between off-premise and on-premise signs is common in sign regulation. This classification originally distinguished different types of signs, as on-premise signs were usually wall or other signs attached to a building, while off-premise signs were freestanding. In addition, on-premise signs usually advertised goods and services sold on the premises, while off-premise signs usually advertised goods and services not sold on the premises. The term "billboard" is often used for off-premise signs, especially when they are adjacent to highways.(45) Sign regulations picked up these differences by defining off-premise and on-premise signs to reflect the functions they serve. They defined on-premise signs as signs that advertise goods and services sold on the premises. They defined off-premise signs as signs that advertise goods and services not sold on the premises. The ordinance would then allow on-premise signs and prohibit off-premise signs. This type of ordinance does not prohibit off-premise signs that display noncommercial messages. This kind of sign regulation came before the Supreme Court in Metromedia and caused problems under the free speech clause. The plurality opinion upheld a ban on off-premise signs although the ordinance allowed on-premise signs, but struck down the section that prohibited noncommercial messages on on-premise signs. The plurality believed this section improperly favored commercial speech over noncommercial speech. The ordinance sections allowing on-premise but prohibiting off-premise commercial signs created a problem under the second Central Hudson test, which requires an ordinance to "directly advance" the interests it asserts. The problem was that allowing on-premise commercial signs while prohibiting off-premise commercial signs arguably undermined the citys aesthetic and traffic safety interests as on-premise signs can be as visually offensive and as dangerous to traffic. State courts had frequently considered this problem, but had held that this distinction was not a violation of equal protection.(46) The Metromedia plurality upheld this distinction against free speech objections.(47) It noted that state courts and its own prior decisions had found it constitutional; that the city could decide that off-premise advertising presented a "more acute" problem than on-premise advertising; and that it would respect the citys decision to value on-premise commercial advertising more than off-premise commercial advertising. It also held a "commercial enterprise" has a stronger interest in identifying its place of business, and the products or services available there, than it has in "advertising commercial enterprises located elsewhere."(48) This holding is a strong endorsement of ordinances that prohibit off-premise but allow on-premise commercial signs. An important qualification, however, is the clear assumption that the San Diego ordinance prohibited only off-premise commercial signs.(49) The implication is the Court would have held the ordinance invalid as an unconstitutional restriction on noncommercial speech had it prohibited off-premise signs with noncommercial messages. This implication is reinforced by the pluralitys treatment of the provision in the ordinance that did not allow on-premise signs to display noncommercial messages.(50) The plurality held this provision unconstitutional because it decided the city could not prevent a business from displaying "its own ideas or those of others."(51) This particular problem is easily fixed if the ordinance allows on-premise signs to display noncommercial messages.(52) A more difficult problem arises if this holding means a municipality cannot disfavor noncommercial speech by prohibiting it on off-premise signs. 2. The Content Neutrality ProblemThis discussion of the Metromedia plurality suggests a municipality that wants to prohibit off-premise signs faces a serious dilemma. It runs the risk a court will hold its ordinance unconstitutional if it prohibits all off-premise signs, including signs with noncommercial messages. A municipality can avoid this problem by defining an off-premise sign as a sign that "advertise a business, products or services not sold or offered on the premises on which the sign is located."(53) It then runs the risk a court will hold the definition unconstitutional because it is content-based. The plurality in Metromedia did not address the definition problem, but objectors can argue this definition is content-based because it is necessary to look at a sign to decide whether the definition covers it. This argument will not succeed. The Supreme Court rejected it(54) and the lower courts have agreed.(55) Messer v. City of Douglasville(56) went even further, faced the content neutrality issue directly, and held a definition of off-premise signs similar to the one quoted above was content-neutral. It did not regulate speech according its viewpoint, which is forbidden; it regulated the sign based on its location; and it did not legislate a preference for either commercial or noncommercial speech. This is not a unanimous view, as the Supreme Court and some lower courts have held a regulation is content-based when the message conveyed determines whether the speech is subject to restriction.(57) These cases indicate an off-premise sign definition like the one quoted above is content-based. Another approach to the regulation of off-premise signs may be necessary. 3. Prohibiting Off-Premise Signs With Noncommercial SpeechAn ordinance can solve the content neutrality problem by prohibiting signs with both commercial and noncommercial messages, but it will then face other free speech problems. Recall that the Metromedia plurality implied that an ordinance prohibiting off-premise signs with noncommercial messages would be unconstitutional.(58) Some courts have taken this position. For example, in National Advertising Co. v. City of Orange,(59) the Ninth Circuit interpreted a sign ordinance to prohibit off-premise noncommercial and commercial signs and then found this prohibition unconstitutional. It held that noncommercial speech requires more protection than commercial speech, that merely treating commercial and noncommercial speech equally is not enough, and that regulations that are valid for commercial speech may be invalid for noncommercial speech.(60) Other courts have agreed,(61) or upheld off-premise sign prohibitions only when they were limited to signs displaying commercial messages.(62) Other cases upheld ordinances prohibiting off-premise signs with commercial or noncommercial speech only because they were limited to designated areas of the city, such as historic areas.(63) This view is not universal. Some courts upheld a prohibition on off-premise containing both commercial and noncommercial messages,(64) while the Eleventh Circuit eased the off-premise vs. on-premise distinction by holding that all noncommercial speech is on-premise.(65) The constitutionality of prohibiting off-premise signs is even more confused after Discovery Network, Inc. v. City of Cincinnati.(66) There the Supreme Court struck down an ordinance that prohibited the display of commercial newspapers on newsracks but permitted the display of noncommercial newspapers. It held this distinction did not provide the "reasonable fit" between legislative purpose and the means to chosen to achieve that purpose which the third Central Hudson test requires.(67) The Court carefully limited its holding to the facts, however. It noted the city had regulated newsracks under an outdated ordinance enacted long before newsracks became a problem. The apparent purpose of that ordinance was to prevent visual blight caused by littering, not the harm associated with permanent newsracks. Neither had the city calculated the "costs and benefits" of burdening speech with a newsrack prohibition because it had not addressed newsrack problems by regulating their "size, shape, appearance, nor number."(68) The Court also said its holding was "narrow," and that it might be possible for a community to justify the differential treatment of commercial and noncommercial newsracks.(69) This case is important to sign regulation because it considered the converse of the problem considered in Metromedia. By striking down an ordinance that treated commercial speech more severely than noncommercial speech, Discovery Network undermined the Metromedia plurality holding, that a sign ordinance may regulate commercial speech more restrictively. Discovery Network recognized this problem. It distinguished Metromedia in a footnote(70) because that case considered a distinction between off-premise and on-premise signs that "involved disparate treatment of two types of commercial speech." The footnote also emphasized the Metromedia pluralitys holding that off-premise signs require regulation because they present more of a problem than on-premise signs. These statements comfortably distinguished Metromedia, but the Court then confused its treatment of that decision. It continued its footnote with the puzzling comment that Metromedia did not consider a distinction between commercial and noncommercial off-premise billboards "that cause the same esthetic and safety concerns."It said this question was not presented in Metromedia because the San Diego ordinance banned all off-premise billboards "with only a few exceptions." This reading of Metromedia is incorrect. How courts should deal with this confused reading of the Metromedia plurality is not clear. The Seventh Circuit has upheld restrictions on off-premise commercial signs that did not apply to noncommercial signs despite Discovery Networks suggestion that this distinction might be unconstitutional. 4. An Alternate SolutionThis discussion suggests that a regulatory distinction between off-premise and on-premise signs is difficult to make without creating problems under the free speech clause. Neither does this distinction make a useful classification between signs that do and do not present aesthetic problems.(72) On-premise pole signs can present as much of an aesthetic problem as off-premise commercial "billboards." A better approach is to regulate freestanding signs in all locations. The key to a sign ordinance that can effectively do this yet withstand free speech objections lies in comments in Discovery Network. There the Court complained the city had not adopted time, place and manner regulations, such as regulations on "size, shape, appearance, or number," that could remedy the problems caused by newsracks.(73) Similarly, a content-neutral time, place and manner sign ordinance would not make the off-premise vs. on-premise distinction and would not distinguish between commercial and noncommercial speech. It would include a content-neutral definition of a sign(74) and would add time, place and manner regulations for different types of signs, including freestanding signs, no matter where they are.(75) Regulations for freestanding signs could differ in different areas. For example, different regulations could apply in commercial and industrial than in residential districts.(76) The ordinance could also contain a special set of regulations for signs adjacent to highways and located in other areas that have special concerns, such as historic districts.(77) It could also prohibit freestanding signs in designated districts or along designated streets or highways. An ordinance of this kind would be a content-neutral regulation of freestanding signs that does not discriminate against noncommercial speech. III. CONCLUSIONThe Supreme Court has made it clear that the free speech clause applies to sign regulations. What it has not made clear is how municipalities can draft sign regulations that will survive constitutional attack as a violation of the free speech clause. This problem arises in part from ambiguities and confusions in Supreme Court decisions; a Court that cannot remember and apply its own precedent hardly deserves credibility.
