All lawyers in Chicago are required to know the difference between state and federal law so that they can represent their clients accordingly. Each part of the court system has specific cases and offenses that it deals with. The punishments may even change depending on whether a person is charged with a state or federal crime.
The differences started right from the time that the two courts were established. Each state that makes up the USA is allowed to establish its own local and state courts. This would allow justice to be implemented by local people for local people. The role of local courts extends to counties, cities, and municipalities.
