This chapter briefly sets out the purpose of the present text, namely to outline how a civil dispute may be dealt with in the most effective way, using litigation in a modern context. The text offers a sound guide to all the rules and principles that are most important at each stage of the litigation process, and what skills and practical considerations are relevant. The chapter then considers changes relating to the litigation process brought about by Sir Rupert Jackson' Review of Civil Litigation Costs: Final Report published in January 2010. This is followed by discussions of the meaning of ‘effective’ litigation, the overriding objective of litigation, the changing legal environment, and the time and financial aspects of litigation.
