Restitution

The law of restitution is the law of gains-based recovery. It is to be contrasted with the law of compensation, which is the law of loss-based recovery. Obligations to make restitution and obligations to pay compensation are each a type of legal response to events in the real world. When a court orders restitution it orders the defendant to give up his gains to the claimant. When a court orders compensation it orders the defendant to compensate the claimant for his loss.

Restitution, like other legal responses, can be triggered by any one of a variety of causative events. These are events in the real world which trigger a legal response. Broadly speaking, an obligation to make restitution can be triggered by two different types of causative event:

However, it is largely an analysis of principle rather than case law and therefore should have considerable relevance for most common law systems.
