Understanding Discovery in Mass Tort Cases

Discovery is the formal process where parties obtain evidence and information from each other before trial. In mass tort litigation involving thousands of claimants, discovery happens at both individual and collective levels. This phase typically takes the longest and costs the most, often consuming years and generating millions of pages of documents.

The scope of discovery is deliberately broad. Parties can obtain any information reasonably calculated to lead to admissible evidence, even if that information itself wouldn't be admissible at trial. In mass tort cases, courts permit extensive discovery given the substantial claims involved and complex scientific issues requiring thorough investigation.

Coordinated discovery in multidistrict litigation establishes common document repositories, standardized requests, and shared strategies. Court-appointed leadership structures coordinate these activities to prevent chaos when dozens of law firms represent thousands of claimants. This coordination ensures comprehensive evidence development while avoiding duplicative efforts.

Electronic discovery has transformed mass tort litigation by expanding discoverable information while creating technical challenges. Modern corporations generate vast electronic communications and digital files that may contain evidence about product development, safety knowledge, and business decisions. Finding relevant information within millions of files requires sophisticated search technologies and substantial expertise.

Written Discovery Tools

Written discovery includes interrogatories, document requests, and requests for admission. These tools establish factual frameworks and identify evidence before depositions occur.

Interrogatories are written questions requiring written answers under oath, typically limited to 25 questions per party. In mass tort cases, common interrogatories to defendants seek identification of people with product knowledge, descriptions of development processes, and lists of relevant documents. Plaintiffs receive interrogatories about exposure circumstances, medical history, treating physicians, economic losses, and witnesses.

Contention interrogatories ask parties to explain their claims or defenses, forcing specific positions and identifying supporting evidence. These help opposing parties understand what they must disprove and facilitate case resolution.

Document production requests seek paper documents, electronic files, photographs, videos, and other materials. In mass tort cases, these typically seek internal corporate communications about product development, scientific studies, regulatory submissions, manufacturing records, marketing materials, adverse event reports, and prior litigation files.

Privileged documents protected by attorney-client privilege or work product doctrine need not be produced. Parties must create privilege logs describing withheld documents specifically enough for opponents to evaluate privilege claims. These logs may list thousands of documents in major cases.

Document review requires systematic processes for organizing, reviewing, and producing responsive materials. Large productions may need document review attorneys, technology-assisted review using algorithms, and quality control procedures. Parties negotiate production formats including file types, metadata inclusion, and redaction methods.

Requests for admission ask parties to admit or deny specific facts or document authenticity, narrowing trial issues by eliminating need to prove undisputed matters. Failure to respond timely results in automatic admissions.

Depositions and Testimony

Depositions create sworn testimony outside court where attorneys question witnesses while court reporters record everything. This testimony can be used at trial, in motions, or during settlement talks.

Fact witness depositions explore individual knowledge about relevant events and circumstances. Categories include plaintiffs describing their experiences, corporate employees with product knowledge, healthcare providers, researchers, regulatory officials, and others with relevant information. Questioning typically covers background information, then specific topics through detailed questions.

Corporate representative depositions under Federal Rule 30(b)(6) require organizations to designate witnesses prepared to testify about specified topics on behalf of the organization. This ensures corporations cannot evade responsibility by claiming no individual knows the answers. Organizations must prepare designated witnesses through document review and consultation with knowledgeable employees.

Expert witness depositions test qualifications, methodologies, and opinions before trial. These explore educational background, prior testimony history, methodologies used, data considered, assumptions made, alternative approaches considered, and opinion foundations. Defense counsel use plaintiff expert depositions to develop challenges arguing opinions lack scientific foundations.

Deposition preparation requires attorneys to develop questioning outlines, review documents and prior testimony, understand technical subjects, and anticipate responses. Witness preparation involves educating witnesses about deposition processes, reviewing relevant topics, and conducting practice sessions. Proper preparation emphasizes truthful testimony based on actual knowledge rather than coaching false or evasive answers.

Deposition objections preserve rights to challenge questions at trial while allowing depositions to proceed. Common objections address question form, foundation, or privilege. Videotaped depositions create visual records useful for impeaching witnesses or presenting testimony when witnesses are unavailable.

Medical Records and Privacy

Medical records establish injury diagnoses, treatment histories, pre-existing conditions, and causation foundations. However, HIPAA and other privacy laws create requirements that parties must navigate.

Medical authorization forms signed by plaintiffs permit healthcare providers to release records. These must comply with HIPAA by identifying what information may be released, to whom, and for what purposes. Relevant time periods typically extend substantially before and after exposure to identify pre-existing conditions and track disease progression.

Medical record organization requires obtaining records from multiple providers, ensuring completeness, organizing systematically, and conducting detailed review. Medical chronologies summarize records highlighting key events. Expert review evaluates whether records support claimed injuries and causation.

HIPAA-qualified protective orders permit providers to release records in response to discovery when protective orders meeting regulatory requirements are in place. Courts routinely enter these orders in mass tort litigation.

Mental health and substance abuse records receive heightened privacy protections. Discovery may require showing particular relevance and enhanced confidentiality protections.

Independent medical examinations allow defendants to have plaintiffs examined by defense physicians. Federal rules permit such examinations when physical or mental conditions are in controversy and parties show good cause.

Electronic Discovery Challenges

Electronic discovery encompasses identifying, preserving, collecting, reviewing, and producing electronically stored information including emails, databases, social media, and digital files. The volume and complexity require sophisticated approaches and substantial resources.

Preservation obligations arise when litigation is reasonably anticipated, requiring litigation holds preventing destruction of relevant information. Failure to preserve evidence may result in sanctions including adverse inference instructions or evidence exclusion.

Custodian identification determines whose files will be searched. Plaintiff custodians typically include claimants whose communications might be relevant. Defendant custodians include executives, product developers, regulatory staff, and safety personnel.

Search methodology development establishes processes for identifying relevant documents within repositories containing millions of files. Keyword searching uses specific terms while technology-assisted review employs algorithms trained on attorney-coded samples. Parties negotiate methodologies, testing effectiveness and validating reasonable results.

Social media discovery obtains relevant content from platforms where parties may have posted information about injuries or activities. However, discovery must be proportional and relevant rather than seeking embarrassing but irrelevant information.

Cost allocation may require requesting parties to bear some costs when requests are particularly burdensome. Courts consider issue importance, amounts in controversy, and party resources.

Third-Party Discovery

Third-party subpoenas compel non-parties to produce documents or testify. This proves essential for obtaining regulatory submissions, scientific studies, healthcare records, and materials parties themselves don't possess.

Regulatory agency subpoenas seek documents submitted to FDA, EPA, or other agencies. These often prove critical for establishing what defendants told regulators about safety, what testing occurred, and whether information was withheld.

Healthcare provider subpoenas obtain medical records from hospitals, clinics, and physicians. These must comply with HIPAA requirements through protective orders or patient authorizations.

Employer subpoenas seek employment records, payroll information, and benefit records establishing income and economic losses.

Non-party objections may claim requests are burdensome, seek irrelevant information, demand privileged materials, or violate privacy rights. Courts balance non-party interests against legitimate discovery needs.

Discovery Disputes

Discovery disputes arise when parties disagree about scope, production obligations, or privilege claims. Courts resolve these through motion practice.

Meet and confer requirements mandate good faith negotiation attempts before seeking judicial intervention. Parties must demonstrate reasonable efforts toward resolution.

Motions to compel seek court orders requiring discovery compliance. These must specify what information is sought, explain relevance, describe negotiation efforts, and address objections.

Protective orders seek court limits on discovery scope, confidential information protection, or other shields from improper demands. Parties must show good cause such as irrelevant information requests or undue burdens.

Sanctions for violations punish non-compliance through monetary penalties, adverse evidentiary consequences, or case-dispositive sanctions. Courts impose these for bad faith or deliberate non-compliance causing prejudice.
