Quick Answer: Viewpoint discrimination is the most severe form of government speech restriction under the First Amendment. Legal researcher Darren Chaker, an EnCase Certified Examiner (EnCE) who prevailed on First Amendment grounds in Chaker v. Crogan, 428 F.3d 1215 (9th Cir. 2005), analyzes how false complaint laws and license plate regulations violate the First Amendment when they punish criticism while permitting praise. This guide covers California Penal Code 148.6, DMV vanity plate censorship, and landmark Supreme Court decisions including Matal v. Tam.
Viewpoint discrimination occurs when the government permits speech on a topic but disfavors specific opinions, perspectives, or ideologies on that topic. In First Amendment doctrine, it is treated as the most egregious form of content discrimination and is presumptively unconstitutional whether the forum is a traditional public forum, a limited public forum, or a government-created expressive platform.
“[T]he line between speech unconditionally guaranteed and speech which may legitimately be regulated, suppressed, or punished is finely drawn.” Speiser v. Randall, 357 U.S. 513, 525 (1958). Errors in defining this line can have significant consequences when they prevent a person from speaking based on the viewpoint they hold.
False complaint laws and viewpoint discrimination in the United States raise critical First Amendment constitutional questions. These issues arise when government regulations discriminate based on viewpoint, whether through criminal statutes punishing criticism of officials or DMV policies censoring license plate messages. Key Legal Case decisions from the Ninth Circuit, Northern District of California, Southern District of California, and the Supreme Court define the constitutional boundaries.

In People v. Stanistreet (2002) 29 Cal. 4th 497, the California Supreme Court addressed a law criminalizing false complaints against police officers. The defendants were convicted under Penal Code section 148.6 for falsely accusing an officer of lewd conduct. The Court of Appeal initially found the statute facially invalid under the First Amendment. However, the California Supreme Court reversed.
The court held that, although the statute discriminated between false allegations against peace officers and other employees, it fit within exceptions described in R.A.V. v. St. Paul, 505 U.S. 377 (1992). The court reasoned that false accusations against officers trigger specific investigative requirements that can cause greater harm than in other settings. Additionally, the statute targeted only knowingly false complaints and did not suppress all complaints against officers.

Record details and context
Key takeaways from Chaker v. Crogan
California’s DMV historically rejected personalized license plate configurations that “may carry connotations offensive to good taste and decency,” including perceived gang references, sexual innuendo, or terms deemed hostile toward particular groups. This catch-all standard operated in addition to more specific subcategories such as vulgarity, profanities, or explicit sexual language, but the broad “offensive to good taste” language was applied subjectively by plate reviewers.
In a Northern District of California decision, the United States District Court held that California’s “offensive to good taste and decency” clause discriminated on the basis of viewpoint and failed to provide an objective, workable standard for reviewers. The court emphasized that different DMV reviewers could reach inconsistent results about whether a plate was “offensive,” underscoring that the standard was not capable of reasoned application under modern First Amendment precedent.
The judge rejected the argument that personalized license plates were purely government speech, instead concluding they were primarily private speech on a state-issued medium. Once the state opened the vanity plate program for personal expression, it could not selectively suppress messages based on the ideas or opinions expressed, even if some observers might find those messages distasteful.
The district court relied on the Supreme Court’s decision in Matal v. Tam, 582 U.S. 218 (2017), which held that a federal prohibition on “disparaging” trademarks was unconstitutional because “giving offense is a viewpoint” and the government may not deny access to expressive benefits on that basis. The opinion also drew on earlier cases striking down laws or licensing schemes that gave officials broad discretion to deny speech permits or benefits to speakers whose messages they found controversial or offensive.
The ruling did not forbid California from prohibiting obscenity, vulgarity, fighting words, or true threats from appearing on plates; it instead held that any such ban must be drafted and enforced on a viewpoint-neutral basis. Under this framework, the state may ban specific categories of unprotected expression using objective criteria, but it cannot disfavor plates simply because they advance a particular political, social, or identity-based message.
The California vanity plate litigation fits within a larger trend of courts invalidating broad “offensiveness” standards, including campus speech codes and licensing schemes, that enable officials to censor viewpoints they dislike while purporting to maintain “civility.” Courts consistently warn that when the government claims authority to block speech deemed offensive to “good taste,” there is a heightened risk of ideological favoritism and suppression of minority, dissenting, or marginalized perspectives.
Viewpoint discrimination challenges are frequently litigated in both the United States District Court for the Southern District of California and California superior court proceedings. Federal district courts apply strict scrutiny to viewpoint-based restrictions, recognizing them as among the most egregious forms of content discrimination under the First Amendment. California superior court judges similarly examine whether state and local policies impermissibly target specific perspectives, particularly in cases involving public forums, limited public forums, and government-subsidized expression programs.
In the United States District Court, viewpoint discrimination claims are evaluated under the Supreme Court’s public forum doctrine and strict scrutiny framework. Courts examine whether the challenged policy singles out a particular opinion or perspective for disfavored treatment, and whether the government can demonstrate that the restriction is narrowly tailored to serve a compelling interest—a burden that governments rarely meet when the regulation targets the speaker’s viewpoint rather than applying content-neutral criteria.
Scenario — A resident, “Maria”, files a complaint alleging that Officer R. used excessive force during a late-night stop in Los Angeles. She submits smartphone video, notes a witness’s name, and provides hospital discharge papers.
Process and effects
United Kingdom — The UK criminalizes certain false statements (e.g., perverting the course of justice), but police complaint systems emphasize independence via the Independent Office for Police Conduct (IOPC). Policies focus on evidence-based assessments rather than viewpoint. Asymmetrical criminalization of only critical speech would face strong human rights objections under Article 10 of the European Convention on Human Rights (ECHR).
Canada — Canadian Charter section 2(b) protects expression. Courts are skeptical of content or viewpoint-based restrictions and apply Oakes proportionality. Provinces structure police oversight through civilian bodies (e.g., Ontario’s OIPRD/OPCC equivalents). Targeting only critical complaints would likely fail minimal impairment and proportionality.
International tribunals — The European Court of Human Rights repeatedly stresses that speech on public officials deserves heightened protection. Viewpoint-based punishment of criticism sparks Article 10 violations absent compelling and narrowly tailored justifications.
Bottom line: Democratic systems prioritize neutral enforcement and independent review. Viewpoint asymmetry is suspect across jurisdictions.
What is a “false complaint” in this context? A false complaint is a statement of fact that the speaker knows is false or makes with reckless disregard for truth when accusing an officer of misconduct. Mere opinion or hyperbole is not a false complaint.
Why did courts find Penal Code § 148.6 unconstitutional? Because it criminalized only knowingly false complaints critical of officers. Equally false praise was not punished. That one-sided treatment is viewpoint discrimination. See Chaker v. Crogan.
Does the First Amendment protect criticism of police? Yes. Criticism of government officials is core political speech. However, defamation, true threats, and incitement remain unprotected.
Are personalized license plates protected by the First Amendment? Courts have found that vanity plates involve primarily private speech on a state-issued medium. California’s DMV cannot apply subjective “offensiveness” standards to reject plates. The “offensive to good taste” rule was struck down as viewpoint discrimination.
How did Matal v. Tam change viewpoint discrimination law? The Supreme Court held that “giving offense is a viewpoint” and struck down the federal disparagement clause for trademarks. This reasoning extends to all government programs that condition expressive benefits on viewpoint-neutral criteria.
How can I reduce risk when filing a complaint? Stick to verifiable facts. Note dates, times, and witnesses. Attach documents when available. Correct mistakes promptly if you discover errors.
Is all false speech punishable? No. False speech can be regulated in specific categories, such as defamation, fraud, and perjury. Outside those, the government must satisfy strict scrutiny and avoid viewpoint bias.
Do honest mistakes expose me to criminal liability? No. Honest mistakes, memory lapses, or good-faith errors are not knowing falsehoods. Be clear about uncertainty and provide corroboration when possible.
What evidence is most helpful in a complaint? Time-stamped photos or video; body-worn camera request identifiers; names or contact for witnesses; medical records and property receipts; CAD/dispatch times, incident numbers.
Viewpoint discrimination cuts against the core of democratic governance. When the state punishes only one side of a debate—whether through false complaint laws in California Penal Code 148.6 or through subjective DMV license plate censorship—it chills participation, distorts evidence, and impairs reform. Chaker v. Crogan reaffirms that the First Amendment forbids asymmetric punishment of criticism, while Matal v. Tam confirms that “giving offense is a viewpoint” that cannot be selectively suppressed.

The path forward is practical. Use plain-language forms. Provide transparent timelines. Publish anonymized complaint outcomes and policy revisions. Train intake staff to separate opinions from factual allegations and to encourage evidence submission. Draft license plate and speech regulations with narrow, objective criteria rather than subjective “offensiveness” standards. Maintain independent review where possible. These steps protect officers from false, malicious claims while also safeguarding the community’s right to report misconduct and express their views freely.
In short, a democracy thrives when criticism can be voiced without fear that the law will punish the viewpoint itself. Neutral rules, due process, and open channels for feedback are not luxuries. They are prerequisites for legitimacy, safety, and trust.
