Litigation, Disputes & Special Situations

Class Action Litigation

Defense-side counsel for companies facing class and aggregate litigation. We handle class-certification strategy, multidistrict coordination, and class-wide resolution, and we run the matter to contain the exposure before it compounds.

A defendant has 30 days from service to remove a putative class action under the Class Action Fairness Act, which reaches most classes of 100 or more on minimal diversity once the aggregate claims clear its floor; the one-year limit and forum-defendant bar of ordinary removal do not apply. That decision, and whether the first motion aims at the claims or the class definition, is made before the answer is due.

Certification is decided on evidence rather than pleadings, and the order must define the class and the claims it covers. A damages class receives individual notice and the right to opt out; an injunctive class under Rule 23(b)(2) gets neither. Either ruling can go up on a Rule 23(f) petition within 14 days, at the court of appeals' discretion.

A class complaint tolls the limitations period for every absent member until certification is denied, so a defeated class is often followed by individual suits that would otherwise be time-barred, though the tolling does not reach a second class action. We run a company's defense across every forum as one matter under one partner.

What we do

Class and aggregate-litigation defense for companies, from the first exposure assessment through certification, coordination, and resolution.
01

Class-Certification Strategy

Building and arguing the certification position under Rule 23, contesting commonality, typicality, and adequacy, and working to narrow or defeat a class at the stage that so often decides a case.

02

Early Exposure Assessment

Early assessment of a putative class complaint. We size the aggregate exposure, map the claims and defenses, and set a strategy before the matter gathers its own momentum.

03

Multidistrict & Aggregate Coordination

Coordinating a unified defense across consolidated proceedings, including multidistrict litigation, with common discovery, bellwether selection, and a single strategy managed across many related filings.

04

Discovery & Evidence Management

Disciplined management of the document-heavy discovery that class and aggregate matters generate, preserving the record, controlling cost, and shaping the proof on which certification and merits turn.

05

Class-Wide Settlement & Resolution

Structuring class-wide settlements where resolution serves the enterprise, addressing court approval, class notice, and the terms that bind absent class members, all weighed against the cost of contesting the case.

06

Trial & Regulatory Coordination

Trial preparation where a class matter goes the distance, with coordination of the regulatory and insurance exposure that frequently travels alongside it, so the defense is run as one coherent effort.

What you should know

The realities that shape a class action defense strategy.
01

Commonality means common answers

Rule 23(a)(2) is satisfied by a question whose answer is the same for every class member, not by a question every member can ask. Since 2011 the inquiry has been evidentiary and often overlaps the merits, and a defendant who shows the answers vary by store, manager or contract usually wins.

02

Standing is counted per member

In federal court every class member who would recover damages must have a concrete injury, and a statutory violation with no downstream harm is not one. That rule can shrink a technical-violation class to a fraction of the defined one, and the settlement number with it.

03

Damages models are certified too

A class seeking money must show damages can be measured classwide by a method matching the liability theory the court will try. A model that sweeps in losses from conduct not before the court fails predominance under Rule 23(b)(3), so defense experts are retained before certification briefing, not after.

04

The MDL is for pretrial only

The Judicial Panel on Multidistrict Litigation sends related federal cases to one judge for pretrial proceedings under section 1407, and the statute requires remand for trial unless the parties consent otherwise. Bellwether trials there happen by consent, and which cases go first is bargained hard.

05

Settlements are served on the government

A proposed class settlement must be served within 10 days of filing on the U.S. Attorney General and every state attorney general with a resident class member, and final approval cannot issue until 90 days after that service. A member the notice missed may refuse to be bound.

06

Class waivers are tested first

An arbitration clause with a class waiver is enforceable under the Federal Arbitration Act, so a motion to compel individual arbitration often comes first. Whether the plaintiff agreed is state contract law, so the assent record, the click, the checkbox and the version in force, is pulled immediately.

The arc of a defense

How this work runs

From one complaint to one resolution.
  1. Stage 01

    The Putative Class

    A complaint lands with one named plaintiff and a class definition drafted to be as wide as the pleading allows. Before an answer is due, we size the aggregate exposure, map removal and forum options under CAFA, and decide where to aim the early motion: at the claims or at the class itself.

  2. Stage 02

    The Certification Fight

    Discovery is built backward from the Rule 23 elements of commonality, typicality, adequacy, and predominance. Expert work, class-definition attacks, and the certification briefing are constructed as one argument, because the ruling on certification usually sets the settlement value of everything that follows.

  3. Stage 03

    Consolidation & Bellwethers

    When parallel filings are gathered into coordinated or multidistrict proceedings, the defense is run as a single matter: one document record, one privilege posture, and one strategy for bellwether selection, with locally admitted counsel engaged where a forum requires it.

  4. Stage 04

    Resolution That Binds

    The class may be defeated, narrowed, or settled, and in each case the endgame is engineered, from settlement structure and class notice to objectors and final approval under Rule 23(e), so the judgment closes the exposure and leaves no opening for the next complaint.

In a class action, the case is usually decided before the merits are ever reached. Certification is the trial.

Frequently asked

Common questions on class action litigation.
What is class action litigation?

A suit in which one or more named plaintiffs ask to represent everyone similarly situated, so that a judgment or settlement binds people who never appeared. Under Rule 23 the court must find the class numerous, its questions common, its representatives typical and adequate, and, for a damages class, that common questions predominate and a class action is superior to individual suits. Members of a damages class receive notice and may opt out; members of an injunctive class may not. The certification order defines who is in, and from that day the exposure is the class's, not the plaintiff's.

Does Hart David Carson LLP represent plaintiffs or defendants in class actions?

Defendants. Our clients are the companies, boards and funds named in putative class and aggregate matters, and the individuals named alongside them. We also advise before any complaint on the arbitration clauses and class waivers that decide whether a class can be brought at all, and on the disclosure, pricing and data practices that most often generate one. The practice is defense-side only, so no plaintiffs' bar relationship sits across the table from a client's interest.

Why does class certification matter so much?

Because it converts one plaintiff's claim into everyone's. Before certification the defendant faces a single claim and can settle it without court approval; after certification it faces the aggregate, and any settlement needs notice, a fairness hearing and the court's approval under Rule 23(e). The ruling is made on evidence, usually after expert discovery, and it can be appealed within 14 days under Rule 23(f) if the court of appeals agrees to hear it. A denial does not end the matter: tolling stops, and the individual suits begin.

How are multidistrict and aggregate-litigation matters handled?

Related federal cases are centralized by the Judicial Panel on Multidistrict Litigation before a single transferee judge for pretrial proceedings under 28 U.S.C. § 1407, on a motion any party can file. The transferee court manages common discovery, rules on the common motions and typically tries bellwether cases by consent; the statute otherwise requires remand to the original districts for trial. State-court cases cannot be transferred into an MDL, so parallel state proceedings are coordinated by agreement and by protective orders that let one production serve both. We run the company's defense across all of it as one matter, with locally admitted counsel where a forum requires it.

Is settlement always the right outcome in a class action?

No, and the sequence matters more than the instinct. A settlement with the named plaintiff alone before certification needs no court approval but binds no one else. A class-wide settlement must be found fair, reasonable and adequate under Rule 23(e)(2), after notice to the class, the chance to object or opt out, and a hearing, and it cannot receive final approval until 90 days after the state and federal attorneys general have been served with it. Terms that invite objectors, among them a reversion to the defendant or a fee out of proportion to what the class actually receives, cost more in delay than they save. We price the alternatives, including contesting certification and trying the case, before the first number is spoken.

What is at stake for a company in a class action beyond money?

Three things in particular. The settlement must be served on the attorney general of every state with a resident class member, so a private resolution becomes a regulatory briefing, and the class notice itself is a public document that the trade press reads. A certified class judgment binds the company as to every absent member, and findings made along the way can be used against it in the next case. And the insurance program has its own rules: a consent-to-settle clause means the carrier is brought along before the number is agreed, and late notice can forfeit coverage. We manage all three alongside the docket, because they outlast it.
