On October 1, 1975 the criminal justice system of the Commonwealth of Virginia began to operate under revised codes of criminal law and procedure. Enacted during the last legislative session, Titles 18.2 and 19.2 contain an impressive array of new laws with which judges, lawyers, and law enforcement officers should quickly become familiar. In many instances, these new laws go far beyond recodification of existing laws. Several represent substantive changes which are quite controversial and remain hotly debated since the close of the legislative session.
