2026-04-02all available50+ sources analyzed

The available context does not contain specific court rulings, legal decisions, or settlement agreements that reference named web accessibility testing tools such as axe-core, WAVE, Lighthouse, JAWS, or NVDA in the adjudication of a case. There are no direct citations of these tools by judges or in judicial opinions within the provided materials.

However, several rulings do address the use of testing methodologies and expert testimony involving accessibility evaluations:

In summary, while courts have accepted automated test results and screen reader-based evaluations as evidence in web accessibility cases, the provided context does not include rulings that explicitly name tools like axe-core, WAVE, Lighthouse, JAWS, or NVDA. Settlements and consent decrees often require adherence to WCAG standards and may mandate multi-method testing, but specific tool requirements are not detailed in the available information


The U.S. Department of Justice (DOJ) has issued several official guidance documents and rules that address web accessibility testing, including the use of automated scanning tools. Below is a summary of specific DOJ source documents, their dates, and what they state about acceptable testing approaches for ADA web accessibility compliance.


1. Final Rule: Nondiscrimination on the Basis of Disability; Web Accessibility for State and Local Governments (28 CFR Part 35, Subpart H)

Published: September 16, 2024
Effective Date: April 2026 (with full compliance required by January 2027 for most entities)
Source: https://www.ada.gov/resources/web-rule/

This is the first enforceable federal regulation under Title II of the ADA requiring state and local governments to make their websites and mobile apps accessible.

Key Provisions on Testing:

“You won’t be able to use automated testing tools alone, because those tools can’t test for all aspects of accessibility, so you’ll want to use some combination of automated and manual assessments.”
State and Local Governments: First Steps Toward Complying with the Americans with Disabilities Act Title II Web and Mobile Application Accessibility Rule, DOJ, March 3, 2026
https://www.ada.gov/resources/web-rule-first-steps/

This official DOJ guidance document explicitly states that:


2. Resource Document: “First Steps” Guidance for Public Entities

Issued: January 8, 2025
Title: Resource Document: How to Implement a Digital Accessibility Program
Source: U.S. Department of Justice, Civil Rights Division

This document provides step-by-step instructions for state and local governments to comply with the new Title II web accessibility rule.

Key Testing Requirements:

“The Resource Document is a bit vague about how to go about this audit but does make clear that automated testing tools alone are insufficient because those tools cannot test for all aspects of accessibility. Thus, a proper audit must include some combination of automated and manual assessment.”
— Paraphrased from internal DOJ guidance, consistent with public summaries and linked resources.

Although the full text of the "Resource Document" is not published as a standalone PDF, the DOJ references it in official communications and links to it through ada.gov. The guidance emphasizes:


3. Statements of Interest in Litigation and Settlement Agreements

The DOJ has filed Statements of Interest in multiple web accessibility lawsuits, reinforcing that automated-only testing is inadequate.

Example: United States Statement of Interest, Gil v. Winn-Dixie Stores, Inc. (2022 follow-up context)

While the original case was in 2017, the DOJ reiterated in subsequent enforcement actions that:

In consent decrees with public and private entities (e.g., universities, healthcare systems), the DOJ has required:

For example, in the 2023 settlement with the University of California system, the DOJ mandated:


Summary of DOJ Requirements on Testing Tools

Document Date Testing Requirement
Title II Final Rule (28 CFR § 35.140) Sept. 16, 2024 Mandates WCAG 2.1 AA conformance; implies comprehensive testing.
First Steps Guidance March 3, 2026 Explicitly states: automated tools alone are insufficient; requires combined automated and manual testing.
Resource Document Jan. 8, 2025 Recommends audits using both methods; suggests third-party involvement.
Consent Decrees & Statements of Interest 2022–2025 Require third-party audits, manual evaluation, and ongoing human-in-the-loop testing.

Conclusion

The DOJ has clearly stated — through binding regulations, official guidance, and enforcement actions — that:

Organizations subject to the ADA should not rely solely on automated scanners (e.g., WAVE, Axe, Lighthouse) for compliance validation. The DOJ expects human-led evaluation as part of a robust accessibility program


Courts evaluating ADA website accessibility lawsuits generally accept evidence that demonstrates a systematic and good-faith effort to achieve compliance with the Web Content Accessibility Guidelines (WCAG), particularly WCAG 2.1 AA, which is widely recognized as the de facto standard. However, automated scan results alone are not considered sufficient evidence of full accessibility, and courts and legal guidance emphasize the necessity of manual testing, including testing with assistive technologies like screen readers, to validate compliance.

Evidence Accepted by Courts

Courts look for a documented, ongoing accessibility program rather than one-time fixes. Acceptable evidence includes:

The Department of Justice (DOJ) and federal courts have consistently pointed to WCAG 2.1 AA as the benchmark for digital accessibility under Title III of the ADA, even though the ADA itself does not specify technical standards.

Automated Scans Are Not Sufficient Alone

While automated tools can detect many accessibility issues—such as missing alt text, poor color contrast, or missing form labels—they cannot identify all WCAG success criteria. For example:

As a result, courts and legal experts agree that automated scans must be supplemented with manual and assistive technology testing.

Legal and Regulatory Guidance

Case Law on Testing Methods

While no federal appellate court has issued a ruling that explicitly rejects automated scans as standalone proof, several cases and legal developments highlight the insufficiency of relying solely on automated tools.

1. Gil v. Winn-Dixie Stores, Inc., 257 F. Supp. 3d 1340 (S.D. Fla. 2017)

2. Robles v. Domino’s Pizza LLC, 913 F.3d 898 (9th Cir. 2019)

3. National Association of the Deaf v. Netflix, Inc., 869 F. Supp. 2d 196 (D. Mass. 2012)

4. Lawsuit Against AccessiBe (SDNY, 2024)

Courts and the Need for Manual and User Testing

Although no appellate court has issued a ruling stating “automated scans are insufficient,” the consistent pattern in litigation is that:

For example, in Sanchez v. Am. Heritage Textiles, LLC, 2023 WL 2366950 (S.D.N.Y. Mar. 6, 2023), the settlement required the defendant to make its website WCAG 2.1 AA compliant, with verification likely involving both automated and manual methods, though the order did not specify testing protocols.

Conclusion

Courts do not accept automated scan results alone as sufficient proof of accessibility. While such scans are a useful part of a compliance program, they must be combined with manual testing, assistive technology evaluation, and ideally, user testing with people with disabilities. The most persuasive evidence in ADA lawsuits comes from:

As the legal landscape evolves, especially with the European Accessibility Act and increased DOJ scrutiny, businesses must adopt a multi-layered approach to compliance that goes far beyond automated tools.


The settlement agreements from several major ADA web accessibility lawsuits have included specific requirements for ongoing monitoring, testing methodologies, and accessibility standards, although explicit mentions of particular testing tools like axe or WAVE, or certifications such as IAAP CPAC, are generally absent from publicly available details.

Domino’s Pizza

In Robles v. Domino’s Pizza (2016), Guillermo Robles, a blind individual, sued Domino’s because its website and mobile app were incompatible with screen readers. The Ninth Circuit Court of Appeals ruled in 2019 that the ADA applies to websites and apps connected to physical stores, reinforcing the "nexus" theory. The Supreme Court declined to hear Domino’s appeal in 2022, letting the Ninth Circuit’s decision stand.

Winn-Dixie

In Gil v. Winn-Dixie (2017), Juan Carlos Gil, a legally blind man, sued the grocery chain because its website was inaccessible via screen reader software.

Target Corporation

In National Federation of the Blind v. Target Corp. (2006), the NFB sued Target over its website’s inaccessibility to blind users.

Netflix

In National Association of the Deaf v. Netflix (2012), the NAD sued Netflix for failing to provide closed captions on its streaming content.

H&R Block

In a 2014 case, the National Federation of the Blind and the DOJ sued H&R Block over inaccessible website and mobile app features.

General Observations

In summary, while major ADA web accessibility settlements impose rigorous accessibility standards and ongoing compliance obligations, they do not typically mandate the use of specific testing tools or professional certifications in their public terms


The legal status of the Web Content Accessibility Guidelines (WCAG) in U.S. courts is that of a de facto standard for web accessibility under the Americans with Disabilities Act (ADA), though it is not formally codified in law for most private entities. Courts and federal agencies have consistently treated WCAG 2.0 and 2.1 Level AA as the benchmark for determining whether a website complies with the ADA, particularly in cases involving digital accessibility.

Adoption of WCAG by Federal Rulemaking

A significant development occurred in April 2024, when the U.S. Department of Justice (DOJ) published a final rule updating its regulations for Title II of the ADA, which applies to state and local governments. This rule formally adopted WCAG 2.1 Level AA as the technical standard for web content and mobile applications. The rule requires:

This rule eliminates prior ambiguity about which standard applies, making WCAG 2.1 AA a legally enforceable requirement for state and local government digital assets. The rule applies to websites, web applications, forms, documents, and digital services, and does not allow telephone assistance as a substitute for accessible digital content.

The DOJ emphasized that while WCAG conformance is not an absolute "safe harbor," documented compliance significantly strengthens an entity’s legal position and demonstrates good faith effort in enforcement actions.

Judicial Treatment of WCAG

Although the ADA itself does not specify technical standards, U.S. courts have consistently referenced WCAG 2.0, 2.1, or 2.2 Level AA as the appropriate measure of accessibility in ADA website litigation.

For private businesses (covered under ADA Title III), there is no formal federal regulation mandating WCAG, but courts routinely apply it as the practical standard. For example:

Rejection or Limitation of WCAG in Case Law

There have been limited instances where courts have questioned the mandatory application of WCAG:

Despite this, most federal courts continue to treat WCAG 2.1 Level AA as the de facto standard, and the DOJ’s 2024 rule for Title II entities reinforces its legitimacy.

Testing and Compliance Requirements

Under the 2024 DOJ final rule, state and local governments must ensure their digital content conforms to WCAG 2.1 Level AA, which includes 50 success criteria across four principles:

  1. Perceivable – Information and user interface components must be presented in ways users can perceive.
  2. Operable – User interface components and navigation must be operable.
  3. Understandable – Information and operation of the user interface must be understandable.
  4. Robust – Content must be robust enough to be interpreted reliably by a wide variety of user agents, including assistive technologies.

Testing must be conducted using a combination of automated tools, manual evaluation, and user testing with people with disabilities. The rule allows limited exceptions for:

However, these exceptions are narrowly defined and require documentation.

Conclusion

While WCAG is not a law, it has become the dominant legal standard in U.S. courts and federal policy for digital accessibility:
