Common misconceptions that judicial review (JR) has grown in usage due to claimants abusing the system, makes public services less efficient, and is a technical detour that rarely alters decisions, are all “at best misleading and at worst false”, according to a 20-month study of 198 JRs by the Public Law Project and the University of Essex. It found that claimants often benefit from JRs and that the rate of success (43%-50%) “does not point to high levels of abuse”.
