““Almost all modern legal practice is derived from one of two distinct traditions. The first, the so-called civil law tradition, is a direct successor to the jurisprudence of the Roman Empire, and it dominates most of the legal systems of continental Europe; the second is the institution known as the common law, used in Britain and its former colonies.
