China does not use a single US-style class-action procedure for every mass claim. Multi-claimant disputes may proceed through ordinary or necessary joinder, representative litigation under the Civil Procedure Law, securities ordinary or special representative proceedings, public-interest litigation, demonstration cases, coordinated individual cases, mediation or another statutory mechanism.
The first task is to define the claimant population, defendants, common and individual issues, remedy, jurisdiction and procedural basis. Preserve claimant-level identity, transaction, causation and loss evidence while building a common record that can be tested consistently across the group.
Subject to editorial and legal review. Court notices, registration periods, limitation and settlement elections can be decisive. Obtain matter-specific advice before organising claimants, publishing solicitations or making procedural elections.
Choose the correct aggregation mechanism
Identify whether claims share the same subject matter, the same type of subject matter, common facts or only a common defendant. Compare joint litigation, representative litigation, separate coordinated cases, a demonstration judgment, public-interest litigation and sector-specific mechanisms. Aggregation must have a legal basis; a large claimant list does not itself create a representative action.
Claimants known when the case begins
Where one side in joint litigation is numerous, the parties may select representatives. The representative's procedural acts bind represented parties, but changing or abandoning claims, admitting the opposing claim or settling requires the represented parties' consent under the Civil Procedure Law. Record identity, authority, claim and consent for each claimant.
Claimants not yet identified
Where claims are of the same type and the numerous parties are not all identified at filing, the court may issue a notice describing the case and claims and set a registration period. Registered rights holders may select representatives; if selection fails, the court may consult with them. The resulting decision binds registered rights holders, while a qualifying person who did not register may bring a claim within the limitation period and seek application of the decision under the statutory framework.
Ordinary securities representative litigation
Securities disputes arising from misrepresentation, insider trading or market manipulation may use ordinary representative procedures under the Civil Procedure Law, Securities Law and the SPC's 2020 provisions. Confirm eligible securities, transaction periods, common facts, defendants, jurisdiction, registration scope, representative selection and investor-specific loss data.
Special securities representative litigation
Under Securities Law Article 95, a qualified investor-protection institution that receives authorisation from at least 50 investors may act as representative. Eligible investors identified through securities-registration information are included unless they expressly opt out. The institution decides whether to participate under its rules; investors cannot assume every securities case will become a special representative proceeding.
Do not confuse public-interest litigation
Public-interest actions protect specified public interests and may be brought only by authorised bodies or procuratorates under governing law. They are not simply private damages claims with many claimants. Consumer, environmental, personal-information and other regimes require separate standing, relief and coordination analysis.
Jurisdiction, notices and registration
Identify the competent court, including special jurisdiction for securities representative cases. Monitor court notices and official registration channels. Build controls for eligibility review, duplicates, withdrawn authority, address changes and late submissions. Avoid collecting excessive personal information or promising an outcome.
Representative authority and governance
Define what representatives and counsel may do, how instructions are obtained, and which decisions require individual consent or special authorisation. Establish conflicts, communications, funding, expenses, confidentiality, privilege and complaint protocols. Maintain an auditable register of appointments, notices, votes and elections.
Common and individual evidence
Separate common evidence—defendant conduct, product design, disclosure, event or policy—from individual evidence of exposure, reliance where relevant, injury, causation and loss. Use standard questionnaires and data dictionaries without erasing material differences. Preserve raw data, source documents, sampling assumptions and expert methods.
Damages and claimant-specific variation
A finding on common liability does not necessarily make every claimant's recovery identical. Model transaction dates, use, exposure, medical or property loss, mitigation, limitation, prior payments and other individual factors. Reconcile aggregate models to claimant-level evidence and design a transparent correction process.
Settlement, mediation and notice
Confirm who can negotiate and bind whom, what consent is required, and whether the court must review or approve the arrangement. Address allocation, proof thresholds, unresolved claims, fees, tax, releases, confidentiality, opt-out or objection rights and default remedies. Communicate material terms in a form claimants can understand.
Defendant coordination and due process
Defendants should build a claimant and issue matrix, preserve common and individual defenses, and test whether aggregation obscures material differences. Challenge unreliable claimant data or expert assumptions through the permitted process while maintaining consistent positions across related cases, regulators and public disclosures.
