Labcorp v. Davis: How the Supreme Court’s Ruling Could Redefine Class Action Litigation for Consumers

The U.S. Supreme Court will hear Laboratory Corporation of America Holdings v. Davis on April 29, 2025, a case poised to reshape the landscape of class action litigation in the United States. At its core, the case asks whether a federal court can certify a class action under Federal Rule of Civil Procedure 23(b)(3) when some class members lack an Article III injury—meaning they suffered no concrete harm. A ruling that bars classes with uninjured members could make it significantly harder for consumers to bring class actions, particularly in cases involving low-dollar claims or harms proven through statistical evidence. This development threatens a vital tool for holding corporations accountable and securing justice for everyday Americans.

With a strong pro-consumer focus, this article unpacks the case’s background, the legal issues at stake, its potential impact on consumers, and practical steps to navigate the fallout. The analysis draws on court documents, legal commentary, and consumer advocacy perspectives to provide a clear, comprehensive picture of why this case matters and what’s at risk.

Background: The Stakes of Class Action Litigation

Class actions allow groups of individuals with similar claims to pool their resources and sue as a collective, often against powerful corporations. They are a cornerstone of consumer protection, enabling plaintiffs to challenge widespread misconduct—like deceptive advertising, illegal fees, or discriminatory practices—without the prohibitive costs of individual lawsuits. In 2023, 10,872 class actions were filed in the U.S., addressing issues from data breaches to workplace discrimination. These cases have secured billions in relief, such as the $5.5 billion Visa-Mastercard settlement in 2019 for overcharged merchants.

The Labcorp v. Davis case stems from a 2020 lawsuit filed in the Central District of California by two legally blind plaintiffs and the American Council for the Blind. They alleged that Labcorp’s self-service check-in kiosks were inaccessible to blind patients, violating the Americans with Disabilities Act (ADA) and California’s Unruh Civil Rights Act, which imposes $4,000 in statutory damages per violation. The plaintiffs sought to certify two classes: a California class for Unruh Act damages and a nationwide class for injunctive relief under the ADA, Affordable Care Act, and Rehabilitation Act. Labcorp argued that the class included many uninjured members—blind individuals who visited its facilities but never tried or intended to use the kiosks—potentially exposing the company to $500 million annually in damages.

The district court certified both classes in 2022, finding that all members faced the same inaccessible kiosks, satisfying Rule 23’s commonality and predominance requirements. The Ninth Circuit affirmed in February 2024, relying on precedent that allows certification even if more than a “de minimis” number of class members are uninjured. Labcorp appealed to the Supreme Court, which granted certiorari on January 24, 2025, to resolve a circuit split on this issue.

The Legal Issue: Article III Standing and Class Certification

The central question in Labcorp v. Davis is whether a federal court can certify a Rule 23(b)(3) damages class when some members lack Article III standing. Article III of the U.S. Constitution requires plaintiffs to show a “concrete, particularized, and actual or imminent” injury to sue in federal court. The Supreme Court’s 2021 decision in TransUnion LLC v. Ramirez clarified that “every class member must have Article III standing to recover individual damages,” but left open whether uninjured members can be included at the certification stage, before damages are awarded.

Federal circuits are divided on this issue, creating inconsistent standards:

• Ninth, Seventh, and Eleventh Circuits: Allow certification unless a significant portion of the class is uninjured, focusing on the named plaintiff’s standing at certification. The Ninth Circuit in Davis ruled that the named plaintiff’s injury (waiting longer due to kiosk inaccessibility) sufficed, even if some class members didn’t attempt to use the kiosks.
• Second and Eighth Circuits: Bar certification if any class members lack standing, arguing Article III applies to all members from the outset.
• First and D.C. Circuits: Permit certification only if the number of uninjured members is “de minimis,” balancing flexibility with constitutional requirements.

Labcorp argues that including uninjured members violates Article III and Rule 23’s predominance requirement, as it forces courts to conduct individualized inquiries to identify harmed plaintiffs. The company claims this inflates liability—potentially by billions in statutory damages cases like the Unruh Act’s $4,000 per violation—and pressures defendants into settlements for claims lacking merit. The plaintiffs, represented by firms like Public Citizen, counter that all class members suffered a cognizable harm: denial of equal access to Labcorp’s services. They argue that Article III doesn’t require every member to prove injury at certification, citing cases like Tyson Foods v. Bouaphakeo (2016), where the Court upheld a class with some uninjured members.

The Supreme Court’s ruling, expected by June 2025, will set a national standard, with briefing due in March and April 2025 and oral arguments on April 29.

Consumer Impact: Why This Case Matters

A ruling in Labcorp’s favor could gut consumers’ ability to seek justice through class actions, with profound consequences:

• Barriers to Low-Dollar Claims: Many class actions involve small individual harms, like $10 illegal bank fees or $50 defective products, which are uneconomical to litigate individually. If courts require proof of injury for every class member before certification, plaintiffs’ lawyers would need extensive data—payroll records, purchase histories, or expert analyses—driving up costs and making such cases impractical. AARP’s amicus brief highlights a hypothetical National Guard class action for discriminatory leave policies, noting that requiring individual payroll and military records upfront could derail meritorious claims.
• Weakened Statutory Protections: Laws like the ADA, Fair Credit Reporting Act, or Telephone Consumer Protection Act rely on statutory damages to deter corporate misconduct. Labcorp’s position could limit these cases by excluding class members who faced violations but didn’t suffer tangible harm, reducing corporate accountability. For example, in false advertising cases, consumers who wouldn’t have bought a product without misleading claims could be deemed “uninjured” if they used the product without issue.
• Disproportionate Harm to Vulnerable Groups: Class actions are critical for marginalized communities, like the disabled plaintiffs in Davis or low-income consumers challenging predatory fees. A strict standing rule could exclude plaintiffs who were exposed to violations but didn’t act (e.g., blind patients who avoided kiosks), undermining protections for those most in need.
• Settlement Pressure on Consumers: While Labcorp claims certification inflates liability, a ruling against class actions could weaken plaintiffs’ leverage, forcing them into lowball settlements or abandoning claims. The American Antitrust Institute warns this could disrupt antitrust cases, where class actions recover billions for overcharged consumers.

Conversely, a ruling for the plaintiffs would preserve flexibility, allowing classes with some uninjured members if common issues predominate. This aligns with consumer interests by enabling lawsuits that address systemic wrongs, like Labcorp’s inaccessible kiosks, without requiring every plaintiff to prove harm upfront.

Strengths of the Current System: Empowering Consumers

Class actions, as upheld by the Ninth Circuit, are a powerful consumer tool:

• Collective Redress: They enable millions to recover for widespread harms, like the $1.2 billion Equifax settlement for 147 million data breach victims in 2019.
• Deterrence: Statutory damages incentivize compliance, as seen in $650 million in TCPA settlements for robocall violations in 2023.
• Access to Justice: By pooling resources, class actions make litigation viable for low-income plaintiffs, who can’t afford solo lawsuits costing $100,000+.
• Efficiency: Courts resolve thousands of claims in one case, reducing judicial backlog. The Davis class, potentially including thousands of blind patients, avoids repetitive individual suits.

Weaknesses of Labcorp’s Position: A Corporate Shield

Labcorp’s argument, backed by groups like the American Bankers Association and National Federation of Independent Business, prioritizes corporate interests over consumers:

• Inflated Liability Myth: Labcorp claims uninjured members drive up damages, but courts already filter out such claims post-certification, as in Tyson Foods. The Davis district court noted Labcorp’s patient records simplify identifying harmed class members, undermining this concern.
• Ignoring Consumer Realities: Many harms, like denial of access or deceptive practices, don’t yield immediate financial loss but still violate rights. Excluding these plaintiffs dismisses legitimate grievances, letting companies off the hook.
• Burden on Plaintiffs: Requiring individualized injury proof at certification demands costly discovery, deterring lawsuits for low-dollar claims. The AARP notes this could block cases like workplace discrimination, where harm varies across a class.
• Corporate Favoritism: Labcorp’s allies, like the Mortgage Bankers Association, argue statutory damages weren’t meant for classes, but these laws exist to protect consumers, not limit their remedies. A strict ruling would shield violators, not promote fairness.

Overreach or Necessary Clarification?

Labcorp frames the Ninth Circuit’s approach as constitutional overreach, claiming it flouts TransUnion’s standing mandate. However, TransUnion addressed post-trial damages, not certification, and the Ninth Circuit’s precedent aligns with Rule 23’s flexibility. The plaintiffs argue that Article III is satisfied if the named plaintiff has standing, with uninjured members addressed later, avoiding premature constitutional barriers.

The corporate push for a strict ruling smells like posturing to curb litigation. Groups like the ABA and NFIB cite small business burdens, but Davis targets a $19 billion corporation, not mom-and-pop shops. Their amicus briefs exaggerate settlement pressures, ignoring that defendants often seek broad classes for “global peace” in settlements, as noted by legal scholars in a Cohen Milstein brief. A ruling for Labcorp would hand corporations a shield, not clarify law.

Recommendations: Protecting Consumer Rights

Until the Supreme Court rules, consumers can take these steps:

1. Document Harms: If affected by corporate misconduct (e.g., inaccessible services, illegal fees), keep records like receipts, screenshots, or medical visit logs to prove injury in potential class actions.
2. Join Advocacy Efforts: Support groups like Public Citizen (citizen.org) and AARP (aarp.org), which are filing amicus briefs to defend class actions. Sign petitions at ConsumerReports.org to urge Congress to protect Rule 23.
3. Monitor Class Actions: Check ClassAction.org for ongoing lawsuits you may join, especially for ADA, consumer fraud, or data breach claims.
4. Engage Lawmakers: Contact representatives via House.gov to advocate for legislation preserving class action access, citing the $5.5 billion in consumer relief from 2019 settlements.
5. Stay Informed: Follow updates on Davis through SCOTUSblog (scotusblog.com) or X accounts like @PublicCitizen for real-time developments.

Conclusion: Defending a Consumer Lifeline

Labcorp v. Davis is a pivotal moment for consumer rights. Class actions are a lifeline for millions, enabling justice against corporate giants like Labcorp, whose inaccessible kiosks denied equal access to blind patients. A ruling barring classes with uninjured members could cripple this tool, blocking low-dollar and statutory claims, harming vulnerable groups, and letting corporations evade accountability. Consumers deserve a system that upholds their rights, not one that erects barriers to the courthouse.

The Supreme Court’s decision, due by June 2025, will shape litigation for years. Stay vigilant, document your claims, and support advocates fighting for your voice. The April 29 arguments are a battle for fairness—join the fight to ensure class actions remain a powerful weapon for consumer justice.
