Bangor Law School’s research into the work of the Administrative Court and the regional market for legal services in public law has challenged the orthodox view that public law is the preserve of London. It has; 1. Provided evidence that regional Administrative Courts are at least equal to the Royal Courts of Justice in terms of their service to users. 2. Influenced the National Assembly for Wales in assessing the case for establishing a separate legal jurisdiction. 3. Influenced solicitors’ instruction patterns in the English regions and Wales, leading to the direction of more work to regional courts and more local solicitors instructing local counsel. 4. Informed national debate about the constitutional role of judicial review. 5. Influenced the Administrative Court/ Public Law Project in developing training opportunities outside London.
