 These do not exist in most countries, and what will usually happen is that one case will be funded as a "test case", and if judgment falls in the claimants' favour the tortfeasor will settle remaining claims.Class actions are justified on the basis that they ensure equal treatment of similarly situated victims, avoid the risk of conflicting judgments on similar issues, and allow an efficient resolution of a large number of claims.In the US, class actions have been used (and by some views abused) in order to overcome the differences applicable in different jurisdictions, including the perceived predispositions of judges, juries, and differences in substantive or procedural law.
