All agencies established through legislation will be given a statutory remit that defines the scope of their authority. A simple paradigm is of agency established on the following terms: if an employee is injured at work the agency may grant compensation. Courts will have to decide on the appropriate test for review when it is claimed that the agency adopted an incorrect meaning of the term employee, injury or work. The test adopted will reflect judicial choice as to the correct balance between agency autonomy and judicial control. Courts in the USA and in the UK have not always been of like mind on this issue.
