Duhaime's Ancient Common Law Dictionary

Duhaime's Ancient Common Law Dictionary

  • The common law is an old man; well over a thousand years old. As law evolved to the modern yet complex body that it is today, many ancient concepts, theories and terms have been left on the wayside. Many are criminal in nature but many reflect civil law issues as well. Some are Latin or French in origin as both languages permeated deeply into the English law psyche. Many were only weeded out more recently in the history of the common law. In some cases (eg. novation), some still have a strong yet foreign-language heartbeat within the fortress of the common law.
  • Duhaime's Ancient Common Law Dictionary sets down for time immemorial those old, disused and sometimes lost terms otherwise forever buried in the cemetery of the common law, and so we can remember from whence our law came.
