The rule of law is an essential part of any democratic society. A central set of rules that everyone must follow is required to prevent arbitrary rule and, ultimately, total anarchy. Having said this, the rule of law does not simply lay down a set of rules and apply them tyrannically. The rule of law has a much wider scope and considers how the laws should be applied and adapted to deal with societal changes and local customs. It is this overall framework of rules tainted with a degree of political and judicial discretion that makes the rule of law an ongoing success in dealing with the vagaries of human nature.
