California Age-Appropriate Design Code in 2026: The NetChoice Ruling, DPIAs and What Survives for Advertisers
California's Age-Appropriate Design Code has been narrowed by the courts, not erased. A 2026 Ninth Circuit ruling reshaped which provisions survive for advertisers.
The California Age-Appropriate Design Code Act, enacted as AB 2273 in 2022, is a children's online-safety law that requires online services likely to be accessed by children to prioritize their privacy and well-being by design, and it has been the subject of a long-running First Amendment challenge by the trade association NetChoice. The litigation, NetChoice v. Bonta, has narrowed the law rather than settling it cleanly. In 2024 the US Court of Appeals for the Ninth Circuit addressed the law's Data Protection Impact Assessment requirement and concluded that compelling businesses to produce DPIAs assessing whether their content could harm children likely violated the First Amendment as compelled speech, and that part of the injunction was affirmed. In a further ruling in 2026, according to law-firm and industry reporting on the decision, the Ninth Circuit issued a split outcome that narrowed the broader injunction: it held that NetChoice had not met the demanding standard for facial First Amendment relief as to the act's coverage definition and its age-estimation provision, while agreeing that certain provisions, including challenged data-use restrictions and the dark-patterns prohibition, raised vagueness and speech concerns, and it returned the case to the district court for further proceedings on issues such as age estimation and severability. The net effect is that the AADC is partially enjoined and partially live, its precise enforceable scope is unsettled, and its status should be confirmed against current official and court sources before relying on any single provision. What is durable for advertisers is the direction: data minimization for minors, high-privacy defaults, and scrutiny of manipulative design.

What the California AADC Is
The California Age-Appropriate Design Code Act, passed as Assembly Bill 2273 in 2022, requires businesses that provide online services, products or features likely to be accessed by children to design those experiences with children's privacy and well-being as a priority. Modeled in spirit on the United Kingdom's Children's Code, it pushes services toward high-privacy defaults for minors, data minimization, and the avoidance of design that could harm or manipulate children.
For advertisers, the AADC matters because it targets the data practices and design patterns that underpin much of how younger audiences are monetized — extensive data collection, default settings tuned for engagement, and persuasive design. Even in its contested, partially enjoined state, it signals a regulatory direction that advertisers cannot ignore.
"The Age-Appropriate Design Code is not a single rule that stands or falls as a whole. The courts have been disassembling it provision by provision, and what survives is what advertisers must actually plan around.

The NetChoice v. Bonta Challenge
The AADC has never had a clean run at enforcement because the trade association NetChoice challenged it on First Amendment grounds almost immediately, and the courts have engaged seriously with those arguments.
The Shape of the Dispute
- The core claim: NetChoice argued that the AADC regulates protected speech and compels businesses to act as arbiters of what content could harm children, raising First Amendment problems.
- Early injunction: A federal district court initially enjoined the law, finding NetChoice likely to succeed on significant parts of its challenge.
- Appellate engagement: The Ninth Circuit took up the appeal and, rather than ruling the whole law in or out, examined its provisions separately — a pattern that has defined the case.
This provision-by-provision approach is why the AADC's status is genuinely mixed rather than simply "blocked" or "in force." For the parallel NetChoice litigation strategy across state minor-safety laws, see the state age-verification guide, and define terms with the compliance glossary.
What the 2026 Ruling Changed
According to law-firm and industry reporting on the decision, the Ninth Circuit issued a further ruling in 2026 that narrowed the injunction against the AADC and reframed which provisions remain blocked, producing a genuinely split result.
The Split Outcome
- Facial relief narrowed: The court held that NetChoice had not met the demanding standard for facial First Amendment relief as to the act's coverage definition and its age-estimation provision, meaning the broad injunction was too sweeping.
- Some provisions still suspect: The court agreed that certain provisions — including challenged data-use restrictions and the dark-patterns prohibition — raised vagueness or speech concerns.
- Remand: The case was returned to the district court for further proceedings on issues such as the age-estimation requirement and severability — that is, which parts can stand independently.
Provision Status at a Glance
| Provision | Judicial posture (per reporting on the rulings) |
|---|---|
| Data Protection Impact Assessment (DPIA) | Enjoined as likely compelled speech |
| Coverage definition | Facial relief not met; injunction narrowed |
| Age-estimation requirement | Remanded for further proceedings |
| Data-use restrictions | Raised vagueness or speech concerns |
| Dark-patterns prohibition | Raised vagueness or speech concerns |
The practical takeaway is that the AADC is neither fully enjoined nor fully enforceable; its enforceable scope is being decided piece by piece, and the 2026 ruling moved the line rather than ending the contest. Because court outcomes can be appealed and refined, confirm the current status against official court sources before relying on any provision. Track the case on the Policy Change Tracker.
DPIAs and the Compelled-Speech Problem
The provision that has drawn the clearest judicial skepticism is the Data Protection Impact Assessment requirement, and understanding why illuminates the whole case.
Why the DPIA Requirement Is Vulnerable
- The requirement: The AADC would require covered businesses to complete DPIAs assessing, among other things, whether the design of their service could harm children, including exposure to harmful or potentially harmful content.
- The constitutional objection: In 2024 the Ninth Circuit concluded that compelling businesses to opine on whether content could harm children likely amounts to compelled speech and effectively presses private companies into judging and policing lawful content, which raises serious First Amendment concerns.
- The status: That reasoning supported keeping the DPIA requirement enjoined, and it has been among the most durable parts of the injunction.
The lesson for regulators and businesses alike is that obligations forcing companies to assess and act on the harmfulness of content are constitutionally fragile in the US in a way that pure data-handling rules are not. For the contrast with the EU approach, where impact assessments sit in a different constitutional setting, see the European Union DSA compliance guide.
What Still Matters for Advertisers
Even with parts of the AADC enjoined, advertisers should not treat the law as irrelevant, because the durable direction it represents is reinforced by other laws that are firmly in force.
The Durable Signals
- Data minimization for minors: Collecting less data from children and teens, and not using their data for purposes beyond what is necessary, is a direction shared with COPPA's amendments and multiple state privacy laws.
- High-privacy defaults: Defaulting minors to the most protective settings, rather than requiring them to opt out, is a pattern regulators consistently favor.
- Scrutiny of manipulative design: Dark-patterns prohibitions appear across privacy and consumer-protection law, so avoiding manipulative design for minors is prudent regardless of the AADC's fate.
- Targeted-advertising limits: Restrictions on profiling and targeted advertising to minors are a recurring feature of the broader legal landscape.
In other words, the AADC's enforceable scope is uncertain, but the compliance posture it points toward is the safe one to build, because converging laws demand much of the same.

How to Prepare Amid Uncertainty
The right response to a partially enjoined, still-litigated law is not to wait for final resolution but to build to the durable direction while monitoring the specifics.
Preparation Steps
- Identify child-likely services: Determine which of your services are likely to be accessed by children, because that is the trigger concept that the broader minors-protection wave shares.
- Minimize minors' data: Reduce collection and restrict use of data from minors to what is necessary, aligning with COPPA and state privacy laws that are in force.
- Default to high privacy: Set the most protective defaults for users known or likely to be minors.
- Remove manipulative design: Audit for dark patterns aimed at minors and remove them.
- Limit targeted advertising to minors: Avoid profiling-based targeted advertising to minors, consistent with the converging legal direction.
- Monitor the litigation: Track the case's progress and confirm enforceable scope against official sources before relying on any single provision.
