Case Study: Class action defense in Americas

Defending a class action in the Americas is one of the most resource-intensive challenges a business can face. A single certification ruling can transform a manageable individual dispute into a liability exposure running into tens or hundreds of millions of dollars. This article examines the procedural architecture of class action defense across the United States, Brazil, Mexico, and Canada, identifies the critical intervention points, and maps the strategic choices available to corporate defendants at each stage. Readers will gain a practical framework covering pre-certification tactics, merits defense, settlement economics, and cross-border coordination.

Class action and collective action mechanisms vary significantly across the Americas, but they share a common structural logic: a representative plaintiff or public authority aggregates individual claims into a single proceeding, creating systemic exposure for the defendant.

In the United States, the Federal Rules of Civil Procedure Rule 23 (правило 23 Федеральных правил гражданского судопроизводства) governs class actions in federal courts. Rule 23 requires the plaintiff to satisfy four threshold requirements - numerosity, commonality, typicality, and adequacy of representation - before a class can be certified. Certification is not automatic; it is a contested judicial determination, and defeating certification is often the single most important objective in U.S. class action defense.

In Brazil, the Ação Civil Pública (public civil action) under Law No. 7,347/1985 and the Código de Defesa do Consumidor (Consumer Defense Code), Law No. 8,078/1990, Articles 81-104, create a robust collective litigation framework. Brazilian collective actions are typically brought by the Ministério Público (Public Prosecutor';s Office), consumer protection agencies, or civil associations. Individual opt-in is not required; the judgment binds the class automatically unless the individual opts out within a defined period.

In Mexico, the Acciones Colectivas (collective actions) were introduced into the Código Federal de Procedimientos Civiles (Federal Code of Civil Procedure) in 2011, Articles 578-625. The mechanism covers diffuse, collective, and individual homogeneous rights. Standing is restricted to the Procuraduría Federal del Consumidor (PROFECO), the Comisión Nacional para la Protección y Defensa de los Usuarios de Servicios Financieros (CONDUSEF), and certain civil associations, which limits the volume of filings compared to the U.S. model.

In Canada, each province has its own class proceedings legislation, with Ontario';s Class Proceedings Act (Закон об исках в защиту класса) of 1992 serving as the most influential model. Canadian courts apply a certification test that broadly mirrors Rule 23 but with a lower threshold for commonality, making certification somewhat easier to obtain than in U.S. federal courts.

Understanding which jurisdiction';s rules apply - and whether multiple jurisdictions are simultaneously engaged - is the first strategic decision in any cross-border class action defense.

The period before a class is certified is where defense resources generate the highest return. A successful challenge to certification eliminates the systemic exposure entirely, reducing the case to manageable individual claims or prompting early settlement on favorable terms.

The core pre-certification tools available to defendants include:

• Attacking numerosity by demonstrating that the proposed class is too small or too heterogeneous to warrant collective treatment.
• Challenging commonality and typicality by showing that individual issues predominate over shared questions, making collective adjudication impractical.
• Contesting the adequacy of the named plaintiff or class counsel, particularly where conflicts of interest or limited resources are present.
• Filing a motion to strike class allegations at the pleading stage, before full discovery begins, where the complaint itself reveals fatal deficiencies.
• Seeking an early Daubert hearing (слушание по стандартам допустимости экспертных заключений) to exclude the plaintiff';s expert whose model is used to establish class-wide damages.

In practice, the most effective pre-certification defense combines procedural challenges with substantive factual development. Defendants who invest in early discovery - deposing the named plaintiff, obtaining internal communications of class counsel, and retaining their own expert on class-wide injury - consistently achieve better outcomes than those who treat certification as a formality to be addressed later.

A common mistake made by international companies unfamiliar with U.S. procedure is to treat the class action as equivalent to a group of individual claims that can be managed sequentially. The certification ruling changes the litigation economics entirely: once a class of 500,000 consumers is certified, even a $10 per-person claim creates a $5 million floor for settlement, and litigation costs on both sides escalate sharply.

The certification hearing is a mini-trial on the class action';s structural validity. Courts in the United States, following the Supreme Court';s guidance in the Comcast line of decisions, require plaintiffs to demonstrate that damages are capable of measurement on a class-wide basis using a common methodology. Defendants who successfully challenge the damages model at certification can defeat the class even where liability questions are shared.

The evidentiary record at certification typically includes expert reports on market structure, consumer behavior, and damages methodology. Defense experts must address three questions: whether the alleged harm actually occurred on a class-wide basis, whether individual circumstances would require separate mini-trials to establish causation, and whether the plaintiff';s damages model is capable of distinguishing injured from uninjured class members.

In Brazilian Ação Civil Pública proceedings, the certification equivalent is the admissibility phase (fase de admissibilidade), where the court evaluates whether the action satisfies the legal requirements for collective standing. Brazilian courts apply a relatively permissive standard, and defendants should focus their early efforts on challenging the associational standing of the plaintiff entity rather than the merits of the underlying claim.

In Mexican collective actions under Articles 585-590 of the Federal Code of Civil Procedure, the court conducts a preliminary certification review within 30 days of filing. Defendants have a limited window to submit preliminary objections (excepciones previas) before the class is formally constituted. Missing this window forfeits important procedural rights.

A non-obvious risk in cross-border class actions is the parallel proceeding problem. A company facing a U.S. class action and a Brazilian Ação Civil Pública simultaneously must coordinate its litigation positions carefully. Admissions made in one jurisdiction can be used as evidence in another, and settlement of one proceeding does not automatically resolve the other.

The business economics at this stage are significant. Defense costs through the certification hearing in a major U.S. class action typically run from the mid-six figures to the low seven figures in legal fees alone, depending on the complexity of the expert work and the volume of discovery. The decision to fight certification aggressively must be weighed against the cost of early resolution.

When certification is granted, the litigation enters its most dangerous phase for the defendant. The certified class creates settlement pressure that is largely independent of the merits, because the cost and risk of a class-wide trial are so high that rational defendants often settle even strong cases.

Effective post-certification defense requires a parallel strategy: continue to develop the merits defense while simultaneously evaluating settlement economics at each procedural milestone.

The key merits tools available after certification include:

• Summary judgment motions targeting the absence of class-wide evidence of liability or causation.
• Interlocutory appeal of the certification order under Rule 23(f) in U.S. federal courts, which must be filed within 14 days of the certification ruling.
• Decertification motions, available when new evidence or changed circumstances undermine the basis for the original certification.
• Bellwether trials (пробные процессы по репрезентативным делам), where individual class members'; claims are tried first to generate data for settlement valuation.

In Canada, defendants may seek leave to appeal a certification order to the Court of Appeal, but the standard for granting leave is high. Canadian courts have shown increasing willingness to certify classes in product liability, financial services, and data privacy matters, making post-certification merits defense the primary battleground in many Canadian cases.

In Brazil, after the admissibility phase, the merits phase of an Ação Civil Pública proceeds similarly to ordinary civil litigation, with the important difference that the judgment has erga omnes (binding on all) effect for diffuse rights claims. A defendant who loses on the merits faces a judgment that automatically benefits all affected individuals without requiring them to file individual claims.

A practical consideration that many international defendants underappreciate is the role of the litigation funder on the plaintiff';s side. Third-party litigation funding is well-established in the United States, Canada, and Australia, and is growing in Brazil. A funded plaintiff';s counsel has the resources to sustain litigation through multiple years and multiple appeals, eliminating the attrition strategy that sometimes works against unfunded plaintiffs.

Settlement is the outcome in the overwhelming majority of certified class actions in the United States and Canada. The decision to settle, and at what stage, is one of the most consequential strategic choices a defendant makes.

Settlement economics in class actions are driven by four variables: the size of the certified class, the per-member damages model, the probability of prevailing on the merits, and the cost of continued litigation. A rational defendant settles when the expected cost of continued litigation - including the risk-adjusted value of an adverse judgment - exceeds the settlement amount.

The procedural requirements for class action settlement add complexity. Under Rule 23(e), any settlement of a U.S. class action must be approved by the court as fair, reasonable, and adequate. The court evaluates the settlement at a fairness hearing, where objectors may appear and challenge the terms. Class counsel';s fee award is also subject to judicial scrutiny, and courts have increasingly reduced fee requests that appear disproportionate to the benefit delivered to the class.

In Brazil, collective action settlements (Termos de Ajustamento de Conduta, or TAC) are negotiated with the Ministério Público or the relevant public agency and must be filed with the court. A TAC that resolves a Brazilian collective action can be a powerful tool for defendants because it provides broad release language and eliminates the risk of erga omnes adverse judgment.

In Mexico, collective action settlements under Article 617 of the Federal Code of Civil Procedure require court approval and must include a clear description of the class, the relief provided, and the distribution mechanism. Mexican courts have limited experience with large-scale class settlements, and the approval process can be slower than in the United States.

Common mistakes in class action settlement include:

• Settling too early, before the defendant has developed sufficient factual record to understand the true scope of the class and the strength of the merits defense.
• Agreeing to injunctive relief provisions that create ongoing compliance obligations without fully modeling the operational and financial cost.
• Failing to obtain a broad enough release, leaving residual individual claims or parallel regulatory proceedings unresolved.
• Underestimating the objector risk, particularly in high-profile consumer class actions where professional objectors may delay final approval for months or years.

The cost of a non-specialist approach to class action settlement is significant. Defendants who negotiate settlements without experienced class action counsel frequently agree to terms that appear favorable on paper but create substantial hidden liabilities through ambiguous release language or poorly structured injunctive provisions.

Class actions in the Americas rarely exist in isolation. A product liability class action in the United States is frequently accompanied by regulatory investigations by the Federal Trade Commission (FTC) or Consumer Financial Protection Bureau (CFPB), parallel proceedings in Canada or Brazil, and potential enforcement actions in the defendant';s home jurisdiction.

Coordinating defense across multiple jurisdictions requires a unified litigation strategy that addresses three distinct risks: the evidentiary spillover risk, the inconsistent position risk, and the regulatory escalation risk.

The evidentiary spillover risk arises because documents produced in U.S. discovery are often used by plaintiffs'; counsel in parallel foreign proceedings. Defendants must implement a document management protocol that accounts for the different privilege rules in each jurisdiction. Attorney-client privilege under U.S. law does not automatically protect communications that would be privileged under U.S. standards but were created in a foreign jurisdiction.

The inconsistent position risk is particularly acute for multinational companies. A factual concession made in a Brazilian TAC negotiation - for example, an acknowledgment that a product had a design defect - can be introduced as an admission in a U.S. class action. Defense counsel in each jurisdiction must be aware of the positions being taken in parallel proceedings.

The regulatory escalation risk reflects the fact that class action litigation often triggers or accelerates regulatory scrutiny. In the United States, the FTC and state attorneys general monitor class action filings in consumer protection matters and may open parallel investigations. In Brazil, PROCON (Programa de Proteção e Defesa do Consumidor) and the Agência Nacional de Vigilância Sanitária (ANVISA) have authority to impose administrative penalties independently of the outcome of civil collective actions.

Practical scenario one: a U.S.-based technology company faces a data privacy class action in California federal court under the California Consumer Privacy Act (CCPA), simultaneously with a collective action in Brazil under the Lei Geral de Proteção de Dados (LGPD), Law No. 13,709/2018. The company must coordinate its factual narrative on data handling practices across both proceedings while managing a regulatory inquiry from Brazil';s Autoridade Nacional de Proteção de Dados (ANPD). A unified defense team with leads in both jurisdictions is essential to prevent inconsistent positions.

Practical scenario two: a consumer goods manufacturer faces a product liability class action in Ontario, Canada, and a parallel Ação Civil Pública in São Paulo, Brazil. The Canadian proceeding is at the certification stage; the Brazilian proceeding has already been admitted. The company must decide whether to pursue aggressive pre-certification defense in Canada while simultaneously negotiating a TAC in Brazil, or whether a global settlement approach is more efficient. The answer depends on the relative strength of the merits in each jurisdiction and the cost of parallel litigation tracks.

Practical scenario three: a financial services company faces a wage and hour class action in California under the California Labor Code and a parallel collective action in Mexico City under the Ley Federal del Trabajo (Federal Labor Law), Articles 685-991. The California case involves a certified class of 12,000 employees; the Mexican proceeding is at an early stage. The company';s primary exposure is in California, but a Mexican judgment adverse to the company could influence the California settlement negotiations. Sequencing the resolution of the two proceedings is a critical strategic decision.

What is the single greatest risk a defendant faces after a class is certified?

The greatest risk is settlement pressure that is disconnected from the merits. Once a class is certified, the defendant';s potential liability is multiplied by the number of class members, creating a financial exposure that may be catastrophic even if the per-member damages are small. This pressure often forces defendants to settle cases they would win at trial, simply because the cost and risk of a class-wide trial are too high. Defendants who have not invested in a strong pre-certification defense find themselves negotiating from a weak position. The practical response is to treat the certification hearing as the primary battleground and allocate resources accordingly.

How long does a class action typically take to resolve, and what does it cost?

A contested U.S. federal class action from filing to final settlement approval typically takes between three and six years, though complex cases can extend longer. Defense costs through certification and into the merits phase can run from the mid-six figures to several million dollars in legal fees, depending on the size of the class, the complexity of the expert work, and the number of jurisdictions involved. Brazilian Ação Civil Pública proceedings tend to move more slowly through the merits phase but can be resolved more quickly through TAC negotiations. Mexican collective actions are generally the least developed procedurally and can be subject to significant delays. Defendants should model total defense costs across all jurisdictions before deciding on a litigation versus settlement strategy.

When should a defendant consider a global settlement rather than jurisdiction-by-jurisdiction resolution?

A global settlement makes sense when the same underlying conduct is the subject of proceedings in multiple jurisdictions, when the factual record is substantially developed in all jurisdictions, and when the defendant can negotiate a release broad enough to cover all parallel claims. The risk of a global settlement is that it requires simultaneous agreement with multiple plaintiff groups and regulatory authorities, which is logistically complex and may require court approval in each jurisdiction. A jurisdiction-by-jurisdiction approach is preferable when the strength of the merits defense varies significantly across jurisdictions, allowing the defendant to achieve favorable outcomes in some proceedings that improve its negotiating position in others. The choice between these approaches should be made with experienced counsel in each relevant jurisdiction.

Class action defense in the Americas demands early investment, coordinated strategy, and a clear-eyed assessment of litigation economics at every stage. The pre-certification phase offers the highest return on defense resources; the post-certification phase requires parallel merits development and settlement evaluation; and cross-border proceedings require unified coordination to prevent evidentiary and positional inconsistencies. Defendants who treat class actions as ordinary litigation and fail to engage specialized counsel early consistently face worse outcomes and higher total costs.
