He discusses the need for regulation and institutionalization in the mediation system. He compares the arguments for and against regulation. He continues the theme by exploring ways in which a mediation system and the criminal justice system can and need to work together. Ivari ends the discussion by developing a prevention (deterrence) theory around mediation.
