In each of the statutory categories of cases in which claims may be pursued in group proceedings (see: When are the group proceedings allowed?), the claimant, in principle, may bring – as in every civil case – one of the three types of actions: an adjudication action, a declaratory action, or an action for a shaping of a legal relation or right. Furthermore, the Act permits the claim to be limited to establishing defendant’s liability despite the fact that an action for payment could be brought.
