What is a class action lawsuit? How it works, who is eligible, claims

What is a class action lawsuit?

What is a class action lawsuit? It is a single civil case brought by one or a few people, the representative parties or named plaintiffs, on behalf of everyone who shares the same kind of claim against the same defendant. Rule 23(a) of the Federal Rules of Civil Procedure says that one or more members of a class may sue as representative parties on behalf of all members, but only if four conditions are met. The class is normally fixed by a purchase, a period and a place, such as everyone who bought a product in one state over a set number of years. How it works in practice, and who is eligible, depends on the class definition the court approves.

What is a class action lawsuit for? To decide shared questions once. If thousands of buyers each lose a small amount, almost none will pay a lawyer to sue alone. Congress described both sides of the device in the Class Action Fairness Act of 2005, finding that class actions "are an important and valuable part of the legal system when they permit the fair and efficient resolution of legitimate claims of numerous parties" and that abuses in them undermine the judicial system. The Federal Judicial Center, which produces educational materials for federal judges, repeats both findings at the start of its pocket guide on class litigation.

A case is a proposed class action from the day it is filed. Under Rule 23(c)(1)(A) the court must decide "at an early practicable time" whether to certify it as a class action, and until it does, the case is the named plaintiffs' own. The two cases at the top of this tracker show the difference: the Black Rifle Coffee case is a proposed class action with no class certified, while the Ticketmaster case has a certified class, a notice and a trial date.

Class action lawsuit definition: Rule 23, state rules and the federal statute

The class action lawsuit definition used in federal court starts with the text of Rule 23, which governs every class action in the federal district courts. Congress added its own for the jurisdiction statutes: in 28 U.S.C. 1332(d)(1)(B), repeated in section 1711(2), a class action is "any civil action filed under rule 23 of the Federal Rules of Civil Procedure or similar State statute or rule of judicial procedure authorizing an action to be brought by 1 or more representative persons as a class action".

State courts have their own rules, and many follow Rule 23 closely. A state-law class action can still reach federal court: section 1332(d)(2) gives the district courts original jurisdiction when the amount in controversy exceeds $5,000,000, exclusive of interest and costs, and any class member is a citizen of a State different from any defendant. The claims of individual members are added together (section 1332(d)(6)), classes under 100 members are excluded (section 1332(d)(5)(B)), and home-state exceptions let or require a court to decline a local case. The Bakker complaint against Black Rifle Coffee pleads more than $5 million, more than 100 class members and minimal diversity.

How it works: the stages of a federal class action

How does a class action lawsuit work from start to finish? Here is how it works in outline: Rule 23 and the rules around it set a sequence, though a court can reorder parts of it. The Federal Judicial Center notes that the amended rule allows a judge to rule on a motion to dismiss before deciding class certification, and calls that the most efficient practice. The stages below follow the order of the rule, and the diagram that follows them marks each stage with a date from a case on this tracker where one exists.

1. Complaint. A named plaintiff files, defines the proposed class and invokes Rule 23.
2. Motions to dismiss or strike. The defendant tests the complaint under Rule 12.
3. Certification. The court decides whether to certify the class, defines it and appoints class counsel (Rule 23(c)(1) and (g)).
4. Notice. The court directs notice to class members (Rule 23(c)(2)).
5. Exclusion and objection. Members may ask to be excluded from a damages class or object to a settlement (Rule 23(c)(2)(B), (e)(5)).
6. Settlement or judgment. A settlement needs a hearing and court approval; a judgment binds the class (Rule 23(e), (c)(3)).
7. Fees. Class counsel asks the court for fees by motion (Rule 23(h)).
8. Claims and payment. If the result pays money, the administrator processes claims and distributes the fund.

How the diagram was assembled

The eight stages follow the order of the provisions of Rule 23 and Rule 12 as published by Cornell's Legal Information Institute. Each date is a docket entry or an administrator's page for a case on this tracker, read on 23 October 2026: the CourtListener dockets for the Black Rifle Coffee, Eargo, Revance and Ticketmaster cases, and the claims administrator's page for Ticketmaster. Stages 7 and 8 carry no example because no tracked case has reached them. Courts reorder or skip stages, and settlement classes compress several, so the picture is a sequence of the rule, not a forecast for any case.

Who can sue: named plaintiffs, class counsel and the four Rule 23(a) tests

Anyone in the group can offer to represent it, but the court admits a class action only if the four prerequisites in Rule 23(a) are met. The class must be so numerous that joinder of all members is impracticable. There must be questions of law or fact common to the class. The claims of the representative parties must be typical of the claims of the class. And the representatives must fairly and adequately protect the interests of the class. Courts call the four tests numerosity, commonality, typicality and adequacy.

The rule treats the lawyers separately. A court that certifies a class must appoint class counsel, weighing the work done to investigate the claims, experience with class actions, knowledge of the law and the resources committed (Rule 23(g)(1)(A)), and class counsel must "fairly and adequately represent the interests of the class". In securities cases an extra step comes first: 15 U.S.C. 78u-4(a)(3) lets any member of the purported class move, within 60 days after the plaintiff's published notice, to serve as lead plaintiff, with a presumption for the member with the largest financial interest that meets Rule 23. The Silverback Therapeutics case shows it on a docket: filed on 5 November 2021, lead plaintiff appointed on 23 February 2022.

The three kinds of class action under Rule 23(b)

Passing Rule 23(a) is not enough. The class must also fit one of three categories in Rule 23(b). The first covers cases where separate suits would risk inconsistent results for the party opposing the class, or would as a practical matter decide the interests of other members. The second covers cases where the defendant acted on grounds that apply generally to the class, so that an injunction or declaratory relief suits the class as a whole.

The third category, Rule 23(b)(3), sits behind most consumer and securities cases that ask for money. The court must find that common questions predominate over questions affecting only individual members, and that a class action is superior to other ways of resolving the dispute, weighing the members' interest in controlling their own suits, litigation already begun, the desirability of one forum and the difficulty of managing the case. The Bakker complaint pleads Rule 23(a), 23(b)(2) and 23(b)(3) together, which is common when a consumer complaint seeks both damages and an injunction.

How a class is defined and certified

The class definition is the most consequential sentence in the case. The Federal Judicial Center's pocket guide says it identifies the persons entitled to relief, the persons bound by a final judgment and, in a Rule 23(b)(3) action, the persons entitled to notice, and that it must be "precise, objective, and ascertainable". A certification order also lists exclusions, such as the defendant's officers and directors. A court can certify subclasses, or a class limited to particular issues, under Rule 23(c)(4) and (5).

Rule 23(c)(1) governs the certification order. The court decides "at an early practicable time", the order must define the class and the class claims, issues or defenses and appoint class counsel, and it can be altered before final judgment. A court of appeals may permit an appeal from a certification ruling, but the petition is due within 14 days of the order (45 days when a federal party is involved), and the appeal does not stay the case unless a judge orders it (Rule 23(f)).

Many proposed classes never reach this stage. The Eargo securities case was filed on 4 November 2021, and the court granted a motion to dismiss on 31 August 2023 and entered judgment on 12 October 2023, with no class certified. The Silverback case ended with a dismissal with prejudice on 12 April 2023. In the Ticketmaster case the court appointed three class representatives, and the claims administrator reports a jury trial ahead.

Notice: how class members are told

For a class certified under Rule 23(b)(3), or a class proposed for settlement, the court "must direct to class members the best notice that is practicable under the circumstances, including individual notice to all members who can be identified through reasonable effort". Notice may go by mail, electronic means or other appropriate means, and must say in plain language what the action is, how the class is defined, what the claims are, that a member may appear through an attorney, that the court will exclude anyone who asks, how and when to ask, and that a class judgment binds those who stay. For classes under Rule 23(b)(1) or (b)(2), notice is left to the court's discretion.

A live example sits at the Ticketmaster fee class action site run by JND Legal Administration. It states the class as five criteria, lists the options of doing nothing and excluding oneself, names a postmark deadline of 6 July 2026 for exclusion and a trial date of 6 July 2027, and says that no money or benefits are available because the court has not decided whether the defendants did anything wrong and the two sides have not settled. The Federal Judicial Center's pocket guide gives a reach of 70 to 95 percent as the norm for notice programs and calls notices that fail to reach or confuse class members "all too common".

Who is eligible: how a reader finds out whether a class covers them

Who is eligible is answered by the class definition, the part of any class action lawsuit definition that names the group, and by nothing else. A reader can compare it with facts they hold: what was bought or held, where, in which period, and whether an exclusion applies. The Ticketmaster page lists criteria that must all be met: an individual in the United States who bought a primary ticket and paid associated fees for a concert at what the plaintiffs call a major concert venue, directly from Ticketmaster or a Live Nation affiliate, at any point since 2010.

Eligibility does not depend on hiring a lawyer, writing to the court or being a named plaintiff. An eligible person is simply someone the definition covers. In a proposed class action nobody is a class member in the legal sense yet. The Bakker complaint proposes a California class and a New York class, each defined as all persons who purchased the defendant's coffee bags in that state within the statute of limitations, and no notice exists because no class has been certified.

Where to look depends on the stage. Before certification, the complaint and the docket are the sources. After certification or a settlement, the official notice and the case website of the court-approved administrator carry the definition, the deadlines and the contact details. The pocket guide warns that claim-filing services "do not generally add any value to a claim" and that some have absconded with funds.

Staying in, opting out or objecting: what happens if you do nothing

A class member who receives a Rule 23(b)(3) notice has three options. Doing nothing keeps the person in the class. The Ticketmaster page spells out what that means: the person remains a class member, keeps the possibility of money or benefits from a trial or a settlement, is bound by the court's or jury's decision and gives up the right to sue the defendants separately over the same legal claims. For a settlement that pays only on a claim form, doing nothing normally means that no payment is made.

Opting out, by the stated deadline and in the stated manner, takes the person out of the class. The person is not bound by the result, keeps any right to sue separately and gives up any share of a class recovery. The pocket guide cites two empirical studies in which about one in a thousand class members, 0.1 percent, opted out of a proposed settlement, and says opt-outs are more common in mass tort, employment and commercial cases, where individual recoveries are higher, and less common in consumer cases.

Objecting is open to a person who stays in. Rule 23(e)(5)(A) says any class member may object to a proposed settlement, and the objection must state whether it applies to the objector, to a subset of the class or to the whole class, "with specificity" as to the grounds. Rule 23(e)(5)(B) bars payment for giving up an objection or an appeal unless the court approves it after a hearing. The guide reports a 1996 Federal Judicial Center study in which, in about half of the class actions, no member filed a written objection, and the objections that were filed most often challenged attorney fees. For a class certified earlier, the court may refuse to approve a settlement unless members get a new chance to ask for exclusion (Rule 23(e)(4)).

Settlement approval and the fairness hearing

A class action can end without a settlement, through dismissal or a judgment after trial, but the settlement route is the one the rules treat with caution. Rule 23(e) provides that the claims of a certified class, or of a class proposed for settlement, may be settled, dismissed or compromised only with the court's approval. The parties first give the court enough information to decide whether to send notice, and the court directs notice if it will likely be able to approve the proposal and certify the class for judgment on it.

Final approval takes a hearing and a finding. The court may approve a proposal that would bind class members "only after a hearing and only on finding that it is fair, reasonable, and adequate", after considering whether the representatives and class counsel adequately represented the class, whether the proposal was negotiated at arm's length, whether the relief is adequate given the costs, risks and delay of trial and appeal, the method of distributing relief and the terms of any fee award, and whether class members are treated equitably relative to each other.

The Federal Judicial Center's guide treats the hearing as essential even when only the settling lawyers appear, and describes some courts as treating the judge in the settlement phase as a fiduciary of the class. Section 1715 requires the settling defendant to serve notice on the appropriate federal official and the appropriate state official of each state where a class member lives within 10 days of filing, and bars final approval earlier than 90 days after service. Section 1713 bars paying some class members more than others solely because they live closer to the court.

The Revance securities case is the tracked case closest to this stage. It was filed on 10 December 2021, dismissed on 17 January 2025 and appealed, and the docket shows settlement papers filed on 10 August 2026. The terms and any hearing date were not verified for this guide, so the next step the rule requires is a hearing before approval.

Attorney's fees and who pays them

Fees are decided by the judge, not by the lawyers and the defendant alone. Rule 23(h) says that in a certified class action the court "may award reasonable attorney's fees and nontaxable costs that are authorized by law or by the parties' agreement". Class counsel asks by motion at a time the court sets, notice of the motion goes to class members in a reasonable manner, a class member or the paying party may object, and the court may hold a hearing and must state its findings.

The pocket guide explains how courts usually calculate the number. The primary method is a percentage of the actual value to the class of a settlement fund plus the value of any nonmonetary relief. The second multiplies reasonable hours by a market hourly rate, the lodestar, which many appeals courts want as a cross-check. The guide's instruction to judges is plain: do not award fees until the true value of the settlement is known, which means counting claims actually filed. For coupon settlements, 28 U.S.C. 1712 ties the fee to the value of the coupons redeemed.

How to claim and what payouts look like

A claim exists only after a settlement or judgment that pays money, and the official notice is where the details live: the deadline, the way to submit, the proof asked for and how payment will be made. The pocket guide asks judges to consider first whether a claims process is needed at all, since a defendant may hold the data to pay some members automatically, and to keep claim forms simple, with no confusing questions or onerous proof requirements. Where a form is needed, the parties usually propose a claims administrator and a call center with a toll-free number.

A payment equals each valid claim's share of what remains after fees, costs and administration, so its size depends on the fund, the deductions and the number of valid claims. This tracker quotes no typical payout, because the Federal Judicial Center says the data are thin: claims rates and actual recoveries are often unavailable to judges, who should order the parties to report them and place them in the public record.

The guide describes cy pres relief, which literally means "as near as possible", as a distribution to a recipient whose activities come as close as possible to the class's interests, used where each member's loss is so small that the cost of administering a single claim would exceed the benefit. Payments also take time: a judgment approving a settlement can be appealed, and Rule 23(e)(5)(B) and (C) address such appeals, so when payments begin depends on the settlement terms.

Class action versus an individual suit, a mass action and multidistrict litigation

What is a class action lawsuit next to an individual suit? An individual suit has one plaintiff or a few named plaintiffs who each sue for their own claims and nobody else's. Two entries on this tracker show one on a docket. Wann v. Theater Development Fund was filed on 8 November 2022 and terminated on 7 December 2022 after a stipulated dismissal, and Wilkins v. University of Wyoming was filed on 19 September 2022 and ended on 18 August 2023. A suit by a state for its own claims is also not a class action, as in State of Ohio v. Norfolk Southern, filed on 14 March 2023.

A mass action is a different device that the statute defines. Under 28 U.S.C. 1332(d)(11)(B)(i) it is a civil action in which the monetary relief claims of 100 or more persons are proposed to be tried jointly on the ground that they share common questions, and each of those people is a plaintiff, unlike the absent members of a class. Cases coordinated solely for pretrial proceedings are excluded from the definition.

Multidistrict litigation is a coordination tool and not a class action. Under 28 U.S.C. 1407, when civil actions with common questions of fact are pending in different districts, a judicial panel may transfer them to one district for coordinated or consolidated pretrial proceedings and remands each action to its home district at or before the end of those proceedings unless it has ended. The tracker lists Garrison v. Bankman-Fried as stayed, with its claims proceeding in the FTX multidistrict litigation.

Typical timeline: what the tracked cases show

How does a class action lawsuit work on the clock? No rule fixes how long it takes, and the tracked cases give a range with real dates. The Black Rifle Coffee complaint was filed on 3 November 2025, and by 3 March 2026 the defendants' motions to dismiss and to strike were submitted without oral argument. The Eargo and Silverback cases took about 21 and 17 months to reach a dismissal order, and the Ninth Circuit affirmed the Eargo dismissal on 10 January 2025, about 14 months after the notice of appeal of 10 November 2023.

The Revance case ran from December 2021 to a dismissal in January 2025, an appeal and settlement papers in August 2026. The Ticketmaster case was filed on 4 January 2022 and has a trial date of 6 July 2027.

Common myths about class actions

"A class member has to sign up first." In a damages class that has been certified, people who fit the definition are included unless they ask out by the deadline. Signing up, in the sense of filing a claim form, comes later and only if the result pays money.

"Everyone in the class receives a check." Payment depends on the settlement design. Some settlements pay from the defendant's records without a form, many need a valid claim, and some provide only a fund-wide remedy such as cy pres relief or an injunction. The Federal Judicial Center's guide says claims-rate and payout data are often missing, which is why a headline settlement figure says little about what a member receives.

"A filed class action shows the company was in the wrong." A complaint states allegations, and the defendant is entitled to contest every one of them. The Eargo and Silverback cases ended on motions to dismiss, and the dockets record no finding of wrongdoing against anyone. The same holds for Bakker v. Black Rifle Coffee, where the plaintiffs allege and the court has decided nothing on the merits.

The next fixed date among the class actions on this tracker is the Ticketmaster jury trial, set for 6 July 2027 at 9:00 a.m. Pacific in Courtroom 9D of the First Street U.S. Courthouse in Los Angeles, a date the administrator's page itself says may move.
