Britain doesn't have a written constitution but it doesn't mean there is no constitution at all. Unlike the majority of countries in the world, Britain doesn't have a single legal document which states all the fundamental laws. British unwritten or uncodified constitution exists in an abstract sense and is presented in a form of written Acts of Parliament, court judgments and conventions. British Constitution basically means that the Parliament, using the power of the Crown, makes and approves law which no other body can challenge. As the Parliament is the supreme legislative body, when it comes to the courts, the judges may only refer to parliamentary statutes. So in this case, although there is no constitution the way the majority of the world has it, the Acts of Parliament are pretty much the constitution. An Act of Parliament is a primary legislation which contains the formal description of a policy passed in regards to every crime and it is easier to change than a written constitution in the future if there is a necessity to do so.
