Multi-claimant injury cases require a common source theory and claimant-specific proof. Secure the product, batch, labels, purchase and distribution chain, suspected substance or emission, locations and exposure windows before recall, cleanup or disposal. Separate a defective-product case from environmental pollution, workplace exposure, food, drug or occupational-disease regimes because liability and procedure differ.
Preserve originals, serial or batch identifiers, screenshots with metadata, samples under chain of custody, inspection and repair records, medical evidence, complaints and proof of loss. Calendar contractual, statutory, administrative and litigation deadlines separately.
Subject to editorial and legal review. Product, consumer and injury claims are fact-sensitive. Urgent safety, recall, medical, evidence-preservation and limitation issues require case-specific advice.
Define the source and claimant groups
Build a source timeline and classify claimants by product, batch, route, dose, location, symptoms and outcome. Similar allegations are not enough; identify common questions and material individual differences.
Product defect and chain responsibility
Evaluate manufacturing, design and warning defects, compliance with mandatory standards and unreasonable danger. Trace producer, importer, seller, transporter, warehouse, platform and component supplier roles. Preserve samples under a documented chain of custody.
Exposure and causation evidence
Collect medical baselines, diagnoses, biomonitoring where appropriate, environmental or product testing, expert methods and alternative-cause evidence. Avoid premature causal conclusions from temporal association alone. Coordinate testing protocols so samples remain usable across claims.
Recall, reporting and remediation
Assess urgent stop-sale, warning, recall, regulator notification, medical monitoring and cleanup duties. Remediation protects people and may also destroy evidence, so document conditions and samples first where safely possible.
Coordinated proceedings
Chinese civil procedure permits representative mechanisms in qualifying disputes, while public-interest litigation may be available to authorized bodies. Consolidation, model cases or coordinated evidence may improve efficiency, but each claimant’s standing, exposure, causation and loss still require proof.
Damages and settlement design
Separate medical expense, disability, death, property damage, business loss and permitted punitive claims. Use transparent eligibility, proof, valuation, lien or benefit treatment, release and future-claim rules in any group settlement.
