Standing in Website Accessibility Cases: Who Can Sue, and Where the Courts Split

In federal court, a website accessibility plaintiff needs Article III standing: an injury in fact, which courts generally find when a blind or otherwise disabled user encounters barriers on a site connected to a physical business or a service they intend to use. The contested element is intent to return. Several circuits require a plausible allegation that the plaintiff plans to use the business again; tester plaintiffs who visit sites to find violations have had standing upheld in some circuits and questioned in others, and the Supreme Court's decision to dismiss the Acheson Hotels case as moot in 2023 left the tester question open nationally.

Before any court reaches WCAG, screenshots, or remediation, a federal website case can end at the threshold on standing alone. That is not a technicality; it is the doctrine deciding who is allowed to bring the case at all. Businesses that understand the standing map understand their actual exposure, which differs sharply by where they operate and who is filing.

The doctrine is unsettled in a way that matters commercially. A serial plaintiff strategy that works in one circuit can fail at the courthouse door in another, and filings have migrated accordingly.

The injury and the nexus

Courts that find standing typically reason in two steps. The barrier itself, being unable to complete a purchase, book a room, or read essential information with a screen reader, is an informational and dignitary injury once the plaintiff actually encountered it. Then most circuits ask for a connection between the website and a place or service the plaintiff plausibly intends to use: the site of a hotel near a planned trip, a restaurant chain with locations the plaintiff visits, a retailer the plaintiff has bought from before and wants to buy from again.

Pure website only businesses have split courts further. Some have extended the ADA to them; others, notably where the circuit requires a nexus to a physical place, have not, which is one reason state law claims, particularly under California's Unruh Act with its statutory damages, carry so much of the national caseload. The standing analysis in state court is a different and often easier door.

Testers and the intent to return fight

A substantial share of filings come from tester plaintiffs: people who systematically visit websites to identify violations and sue, sometimes filing dozens or hundreds of cases. Defense arguments write themselves, that the plaintiff never intended to buy anything. Several courts have nonetheless found standing where the plaintiff alleged an intent to return to the site and to the business, treating motive as irrelevant to the injury analysis. Others have dismissed testers whose complaints recited intent in boilerplate that their own filing history contradicted.

The Supreme Court granted review on exactly this tester standing question in Acheson Hotels v. Laufer, then dismissed the case as moot in December 2023 after the plaintiff dropped her claims, leaving every circuit's approach in place. Until the Court takes a live case, standing in a tester suit is a forum question first and a merits question second, and any exposure assessment that ignores the circuit is not an assessment.

What this means for a business assessing risk

Standing defenses win cases; they do not remediate websites, and they are useless against the next plaintiff whose intent to return is genuine and local. A business whose site has real barriers in a plaintiff friendly forum is playing a numbers game it eventually loses to a filer with clean standing. The durable strategy remains the unglamorous one: conform the site to WCAG 2.1 AA, document the remediation, and keep the conformance current as templates and third party tools change.

For a business already served, standing belongs in the first evaluation with counsel, alongside the forum, the plaintiff's filing history, and whether state claims ride along. Some cases should be fought at the threshold. Some should settle quickly while remediation proceeds. Choosing between those paths on the first demand letter's dollar figure alone, without the standing analysis, is how defendants pay tester settlements on claims a court may never have entertained.

Frequently asked questions

What is Article III standing in an ADA website case?

It is the constitutional requirement that a federal plaintiff show a concrete, particularized injury that the court can remedy. In website cases it usually means the plaintiff personally encountered barriers and, in many circuits, plausibly intends to return to the business or use its services again.

Can a tester plaintiff who never intended to buy anything sue?

It depends on the circuit. Some courts hold that tester motive does not defeat standing when an intent to return is alleged; others scrutinize boilerplate intent claims against the plaintiff's filing history. The Supreme Court has not resolved the split; its 2023 Acheson Hotels disposition was on mootness grounds.

Does standing work differently for website only businesses?

Yes. Circuits requiring a nexus between the website and a physical place of public accommodation have dismissed some claims against web only businesses, while other courts apply Title III more broadly. Many plaintiffs route around the issue with state law claims, which is why the federal standing map is only part of the exposure picture.

If a case can be dismissed on standing, why remediate?

Because standing is plaintiff specific. The next filer may be a genuine local customer with unimpeachable standing, and the barriers will still be there. Dismissal also does nothing about state agency enforcement or state court claims. Remediation is the only step that reduces every category of risk at once.
