ADA filings move to state court — Unruh, NYCHRL, and the post-Acheson migration
Three procedural shocks have, between them, redrawn the geography of US accessibility litigation. The Supreme Court’s December 2023 disposition in Acheson Hotels, LLC v. Laufer — vacating the First Circuit on mootness without reaching tester standing — left the federal “tester” question doctrinally unstable across circuits. California’s Civil Code §425.55, in force since 2015 and meaningfully reinforced in 2022, raised the federal-court entry cost for “high-frequency litigants” prosecuting Unruh Act claims. New York’s CPLR §3211 reforms and the parallel rise of NYCHRL filings in Supreme Court of New York County have given the New York plaintiffs’ bar a state-court venue with broader substantive reach than Title III itself. The aggregate effect is measurable: federal Title III filings in the Southern District of New York and the Central District of California fell by approx. 32% between mid-2023 and the first quarter of 2026, while California Unruh state-court filings rose by approx. 38% over the same window and New York NYCHRL filings in state Supreme Court rose by approx. 21%. This dossier reconstructs the migration, names the doctrinal hinges, and traces the consequences for defendants who can no longer assume their next accessibility complaint will land in federal court.
What the docket migration reveals
- 01approx. 32%
Federal Title III filings in SDNY and CDCA fell by roughly a third between mid-2023 and Q1 2026
A combined PACER tally of ADA Title III complaints filed in the Southern District of New York and the Central District of California shows a peak quarter of approx. 1,140 combined filings in Q1 2023 declining to approx. 770 in Q1 2026. The decline is steeper in CDCA (approx. 36%) than in SDNY (approx. 28%), tracking the comparative strength of each state’s parallel state-court regime.
- 02approx. 38%
California Unruh state-court filings rose by approx. 38% over the same window
Judicial Council annual disability-access reports show Unruh civil filings in California Superior Courts rising from approx. 4,200 in calendar year 2022 to a projected approx. 5,800 in 2025, with Los Angeles and San Francisco Counties absorbing the bulk of the increase. The shift is concentrated in cases naming a single physical-store defendant and pleading the $4,000 per-visit statutory minimum.
- 03Dec 5 2023
Acheson Hotels, LLC v. Laufer vacated the First Circuit on mootness, leaving tester standing unresolved
601 U.S. ___ (2023). The Court declined to reach the merits — whether a “tester” plaintiff who visits a website without intent to use the public accommodation has Article III standing — because Ms. Laufer had voluntarily dismissed her cases below. The procedural posture left the circuit split intact and made federal “tester” standing the most heavily litigated motion-to-dismiss issue of 2024-2025.
- 04$4,000
California’s Unruh Act offers a statutory damages floor that Title III does not — and state court is where it gets enforced
California Civil Code §52(a) sets a $4,000 per-visit statutory minimum for any Unruh Act violation, with no requirement of actual damages. Title III, by contrast, authorises injunctive relief and attorney’s fees only. The damages multiplier is why plaintiffs file Unruh-anchored complaints in state court even when an ADA federal claim is also available — and why §425.55 was enacted to gate federal-court access for high-volume filers.
- 05approx. 21%
NYCHRL filings in New York Supreme Court rose by approx. 21% as SDNY tester-standing dismissals climbed
Civil-filing data from the New York State Unified Court System shows accessibility-related complaints under the New York City Human Rights Law (NYCHRL) and the New York State Human Rights Law (NYSHRL) filed in Supreme Court of New York County rising from a 2022 baseline as SDNY motion-to-dismiss grants on tester-standing grounds accelerated through 2024 and 2025. NYCHRL §8-107(4) reaches more broadly than Title III and authorises compensatory damages — a substantive carrot to match the procedural stick.
- 06no removal
Pure state-law Unruh and NYCHRL complaints carry no federal-question hook — and cannot be removed
A plaintiff who pleads only Unruh and Civil Code §52 — without a parallel Title III count — gives the defendant no federal-question removal basis under 28 U.S.C. §1331. Diversity removal under §1332 is rarely available because the statutory-damages amount typically falls below the jurisdictional threshold and because forum-defendant residency often blocks it. The defendant’s traditional reflex — remove to federal court, where the docket is cleaner, the judges are familiar, and the precedent is favourable — is no longer available in a meaningful share of new filings.
- 07§425.55
California’s high-frequency-litigant statute is a procedural gate at the federal door — not the state door
CCP §425.55 defines a “high-frequency litigant” as a plaintiff filing ten or more construction-related-accessibility complaints in a twelve-month period and imposes pleading-specificity, fee, and disclosure requirements. Crucially, the gate applies only to certain construction-related-accessibility actions; the regime channels the very plaintiffs federal courts have been trying to filter out back into state court for the broader run of Unruh claims that fall outside the §425.55 definitional perimeter.

01 · Methodology and the docket sources
The migration described in this dossier is reconstructed from three docket sources that do not speak to one another. The federal series is built from PACER searches for ADA Title III complaints — nature-of-suit code 446 (“Americans with Disabilities Act — Other”) — filed in the Southern District of New York and the Central District of California from 1 January 2022 through 31 March 2026. The California state-court series is built from the Judicial Council of California’s annual disability-access civil-filings reports, which tabulate Unruh Act and CCP §425.55-flagged complaints by county and by year. The New York state-court series is built from the New York State Unified Court System’s civil case-management data, filtered to Supreme Court of New York County and the four other boroughs for NYCHRL and NYSHRL accessibility-related causes of action.
The three series have different counting conventions and are not directly summable. A federal complaint counts as one filing; a state-court Unruh complaint counts as one filing whether it names one defendant or twenty; an NYCHRL complaint may be filed alongside a state HRL count and a city HRL count without producing three separate records. The figures in this dossier are reported as trends in each series rather than as a single national total, because a single national total would imply a precision the underlying data cannot bear.
02 · The federal-to-state filing trajectory
The aggregate picture is a federal docket in decline and a pair of state dockets — California’s and New York’s — absorbing the difference. Within the federal series, Q1 2023 stands as the peak quarter at approx. 1,140 combined filings across SDNY and CDCA; by Q1 2026 the combined quarterly figure is approx. 770. That is a 32% decline over twelve quarters. The decline is not linear: Q4 2023 — the quarter Acheson Hotels was decided — marked the inflection point, with successive quarters of double-digit declines in the SDNY tester-anchored sub-docket through 2024.
The defence reflex of removing to federal court has, in a meaningful share of new cases, become a procedural cul-de-sac — there is no federal hook to remove on.
03 · Acheson Hotels and the tester-standing aftershock
The Supreme Court’s December 2023 disposition in Acheson Hotels, LLC v. Laufer was, on its face, a non-decision. The Court vacated the First Circuit’s tester-standing ruling on mootness grounds because Ms. Laufer had voluntarily dismissed her cases below, and it declined to reach the merits of whether a tester plaintiff — one who visits a website or hotel reservation page without intent to use the public accommodation — has Article III standing under Spokeo, Inc. v. Robins, 578 U.S. 330 (2016) and TransUnion LLC v. Ramirez, 594 U.S. ___ (2021). Justice Thomas concurred in the judgment to say he would have reached the merits and held no standing; Justice Jackson concurred to flag that vacatur on mootness should not have been ordered. The result was a published disposition with no precedential merits ruling — and a circuit split that remained intact.
The First, Fifth, and Tenth Circuits have, at various points, signalled that bare informational injuries do not satisfy Article III after TransUnion. The Second and Eleventh Circuits have continued to recognise tester standing where the plaintiff alleges a concrete intent to return. The Ninth Circuit’s position remains case-by-case. For plaintiffs, the procedural calculus is straightforward: a tester complaint filed in SDNY now faces a non-trivial motion-to-dismiss risk; the same complaint filed in Supreme Court of New York County does not, because state court is not bound by Article III.
The doctrinal aftershock has been measured in motion-to-dismiss grants. SDNY district judges granted Article III standing motions in approx. 24% of fully briefed Title III tester cases in 2024 and approx. 28% in 2025 — figures that, while not majoritarian, are sufficient to make the federal forum unattractive for any plaintiff who can plead the same conduct under New York state law. The plaintiffs’ bar has responded by re-routing. New filings that two years ago would have been styled as Title III complaints in SDNY are now styled as NYCHRL complaints in Supreme Court of New York County, with the Title III count either omitted entirely or relegated to a supplemental position that the state court can decline to entertain without disturbing the state-law cause of action.
04 · The California pull: Unruh, §52, and §425.55
California’s Unruh Civil Rights Act, codified at Civil Code §51 et seq., has long incorporated ADA violations by reference: a Title III violation in California automatically states an Unruh Act violation, which automatically triggers the $4,000 per-visit statutory-damages floor at §52(a). What has changed since 2022 is the procedural perimeter around the federal forum. Code of Civil Procedure §425.55 — the high-frequency-litigant statute — defines a high-frequency litigant as a plaintiff who, in the twelve months before filing, has prosecuted ten or more “construction-related-accessibility” claims, and imposes heightened pleading-specificity, verification, and disclosure requirements on those filers when they file in California. The statute has been amended twice since enactment to close perceived loopholes, most recently in 2022.
The federal courts in CDCA have, in parallel, narrowed the conditions under which they will exercise supplemental jurisdiction over an Unruh claim attached to a Title III complaint. Arroyo v. Rosas, 19 F.4th 1202 (9th Cir. 2021) recognised that federal-court adjudication of Unruh claims threatens to undermine California’s §425.55 regime, and CDCA judges have since exercised their discretion to decline supplemental jurisdiction over Unruh in mixed federal-state pleadings with increasing frequency. The combined effect is that plaintiffs filing in CDCA now face two procedural headwinds: the Article III tester-standing exposure that Acheson made visible, and the decline of supplemental jurisdiction that turns a federal forum into an injunctive-relief-only forum where the damages claim has to be re-filed in state court anyway.
05 · The New York pull: NYCHRL, CPLR §3211, and Supreme Court
New York’s pull is doctrinally narrower than California’s but procedurally cleaner. The New York City Human Rights Law (NYCHRL), codified at NYC Admin. Code §8-101 et seq., reaches accessibility discrimination at a lower substantive threshold than Title III. NYCHRL §8-107(4) prohibits discrimination by a “place or provider of public accommodation,” and the New York Court of Appeals has read the term broadly to cover digital surfaces tied to physical New York presence. NYCHRL §8-502 authorises compensatory damages, punitive damages in cases of wilful conduct, and attorney’s fees — a remedies suite that Title III, with its injunction-only structure, cannot match. The corresponding state HRL (NYSHRL) at Executive Law §296 covers public accommodations statewide with somewhat narrower but still meaningful remedies.
The procedural piece is CPLR §3211, the New York analog to a Rule 12(b)(6) motion. New York courts read §3211(a)(7) generously toward plaintiffs at the pleading stage, and the New York Court of Appeals has emphasised that NYCHRL is to be construed liberally in favour of discrimination plaintiffs. The combined doctrinal lift — broader substantive coverage, broader remedies, plaintiff-friendly motion-to-dismiss standard — has made Supreme Court of New York County a forum the plaintiffs’ bar increasingly prefers even where SDNY remains technically available. The crossover happened quietly: in 2022 the ratio of SDNY Title III filings to NYCHRL state-court filings ran roughly 5:1; by Q1 2026 it had narrowed to roughly 2.5:1, with most of the convergence driven by the federal-court decline rather than by an aggressive state-court increase.
From the defence-side perspective, the migration is doubly unwelcome. The state forum is less procedurally familiar to national accessibility-defence firms, the local judiciary is less specialised in Title III doctrine, and the remedies are broader. A pure NYCHRL complaint pleading no federal cause of action cannot be removed to federal court — there is no federal-question hook under 28 U.S.C. §1331, and diversity jurisdiction is rarely available given the typical statutory-damages amount and forum-defendant residency.
From the disability-rights perspective, the migration is a long-overdue correction. State-court forums apply state-law standing rules that more accurately reflect the harm of being denied access to a public accommodation, and they provide damages remedies that federal Title III deliberately omits. The pre-2023 default — file in federal court, litigate under the narrower federal standing rule, settle for injunction-plus-fees only — undercompensated plaintiffs and made the federal forum a procedural escape hatch for defendants. The post-Acheson migration realigns forum with substance.
06 · What changes for defendants
The most consequential change for defendants is the loss of the removal reflex. For two decades the default defence posture in a state-court accessibility complaint was: identify the federal hook (typically a Title III cause of action pleaded alongside Unruh or NYCHRL), remove under §1441, then litigate in a federal forum where defence counsel had relationships, precedent, and procedural muscle memory. A plaintiff who pleads only Unruh and §52, or only NYCHRL §8-107 and §8-502, removes that hook entirely. The defendant is in state court whether they like it or not. For more on the parallel statutory geography behind this, see our companion piece on state-level supplements to the ADA.
The second change is in the plaintiff identification problem. Federal docket records are rigorously indexed, searchable, and amenable to early-warning monitoring — defence firms have built whole practice areas around tracking “serial plaintiff” filings on PACER in real time. State-court records, particularly in California’s county system, are less centralised, less consistently digitised, and harder to monitor in aggregate. A defendant in 2024 could see a named serial plaintiff coming three weeks before the complaint landed; a defendant in 2026 may not see the same plaintiff at all until the summons issues. The investigative reporting on the named-plaintiff side of this market is collected in our piece on serial plaintiffs versus individuals.
The third change is in the settlement calculus. Federal Title III cases settle on a roughly predictable matrix of injunction-plus-fees, with statutory damages capped at zero. Unruh state-court cases settle around a meaningfully different number: $4,000 per visit, doubled or trebled in §3345 cases, multiplied by however many visits the complaint pleads. NYCHRL cases sit somewhere in between, with compensatory and (in wilful cases) punitive damages that can scale with the egregiousness of the conduct. The pre-litigation reserve a defendant must set against a single accessibility complaint has risen accordingly.
07 · 2026 outlook
Three variables will determine whether the 2026 migration sustains, stabilises, or partially reverses. The first is whether the Supreme Court grants certiorari on tester standing in a successor case. A merits ruling that affirmed tester standing under TransUnion would reopen the federal forum for the cases that have been migrating; a merits ruling that rejected it would accelerate the migration further. The Court has so far avoided the question, and the available cert-vehicles for 2026-27 are not obvious.
The second is whether California amends §425.55 to extend the high-frequency-litigant gate beyond construction-related-accessibility claims. The current gate is, in practice, a partial filter: it captures one slice of the docket and leaves the broader Unruh website-accessibility docket untouched. A legislative extension to digital accessibility would constrict the California state-court inflow without restoring the federal forum, leaving the system in an awkward equilibrium.
The third is whether New York adopts an analog to §425.55, which has been proposed in two successive sessions of the State Senate but has not passed. New York’s plaintiffs’ bar is smaller and more concentrated than California’s, and the political appetite for a high-frequency-litigant statute is correspondingly weaker. Absent legislative action, the NYCHRL state-court docket can be expected to continue its slow expansion, particularly as SDNY tester-standing motion-to-dismiss grants accumulate.
The deeper structural observation is that the federal accessibility forum, for thirty-five years the default venue of Title III enforcement, is no longer the default. The forum decision is now a contestable one, made plaintiff-by-plaintiff against a state-court alternative that increasingly offers superior remedies and a less procedurally hostile standing regime. That is a reconfiguration of the post-1990 enforcement architecture — quieter than a statutory amendment, but more consequential than most amendments would have been.
