Law is a body of rules supported by the power of govern-ment. It governs the behaviour of all members of society. It is not possible to have a society without laws, as there would be anarchy in society then. Governments make laws and enforce them against all citizens within their power. They have two motives in making and enforcing laws. One is social control; the other is the implementation of justice. To establish social control governments use public law and civil law. Public law ensures the authority of the government itself and civil law provides framework for interaction among people. Justice is a concept that most people feel is very important but few are able to define. Sometimes a just decision is simply a decision that most people feel is fair. New laws appear all the time as our life is changing very fast. But no country has been successful in producing laws, which are entirely satisfactory. Ordinary people start thinking about law only when everyday informal ways of settling disputes break down. When we buy a train ticket, a lawyer may tell us it represents a contract with legal obligations, but to most of us it is just a ticket that gets us on the train. If our neighbour plays loud music late at night, we will probably try to discuss the matter with him rather than consulting the police, lawyers or courts. Only when we are injured in a train accident or when a neighbour refuses to behave reasonably, we start thinking about the legal implications of our everyday activities.
