The . legal system is admired around the world for the freedoms it allows the individual and the fairness with which it attempts to treat all persons. On the surface, it may seem simple, yet those who have delved into it know that this system of federal and state constitutions, statutes, regulations, and common-law decisions is elaborate and complex. It derives from the English common law, but includes principles older than England, along with some principles from other lands. The . legal system, like many others, has a language all its own, but too often it is an unfamiliar language: many concepts are still phrased in Latin.
