In the UK we have ‘rule by law‘, as opposed to rule by one person, a group of people, or by a religion. This means that the law applies to every single citizen, including judges, aristocracy, celebrities, the police and government officials. No-one is entitled to carry out their own form of punishment or to behave in ways that are not allowed by the law of the country.
The rule of law means that everyone has access to justice and similar cases must be treated in exactly the same way, as no-one has the right to be held higher than someone else in the eyes of the law. Legal assistance in prosecution or defence must be affordable, understandable, incorruptible and effective. This basic principle of British life ensures a fair society.
