This book helps candidates preparing for SQE1 to revise the constitutional theories and their workings in the UK, including legitimacy, the rule of law and the separation of powers. It explains how the core institutions of the state interrelate and their respective roles in the constitution. And it covers the key areas of public order, human rights and the status of EU law in the UK constitution following Brexit.
