One of the issues that has bedevilled common law courts is the law of state liability: when does official misconduct give rise to a right of action in damages? Various answers have been given. Usually there is a threshold test of proximity, related in some way to the statute that empowers the decision-maker. And there is usually a blanket exclusion of liability in some circumstances, for what are sometimes described as non-justiciable or policy decisions.
