With court calendars already overcrowded and the number of civil cases steadily mounting, prolonged litigation and successive lawsuits are becoming an increasing burden on plaintiffs, defendants, and the court system alike. The doctrines of res judicata and collateral estoppel, which are well respected by both the bench and the bar, offer the best means for avoiding such situations and for reaching swift and definitive judgement. This volume is the first work to provide clear, fully documented discussion of the subject, even for the nonspecialist attorney or manager. Written by a seasoned legal professional, it incorporates citations and systematic analyses of the most recent applicable case law.
