3.3 Judicial Review
The judiciary in the UK works separately from other parts of the governmentThe public authority that provides services, collects taxes, sets laws and regulations, and helps manage the economy., like Parliament and the Prime Minister. This follows Montesquieu's idea of separation of powers, which means no single part of the government has all the power. Judges have the job of understanding and applying the law. They make sure the law is obeyed and that people's rights are respected and protected.
