Book excerpt: While litigation is often considered a last resort for achieving regulatory objectives, its use can have significant impacts on the regulator and regulated entity, and a consequential impact on industry, government and the public. REGULATION, LITIGATION AND ENFORCEMENT examines the procedural aspects of litigation in the regulatory context from the perspective of theory, policy and practice. It considers litigation issues common to all regulatory schemes, such as investigation and information gathering powers, and criminal law aspects of regulatory litigation. The different regulatory regimes are considered together so that they can be compared and contrasted. REGULATION, LITIGATION AND ENFORCEMENT reviews the need for regulation, forms of regulation and techniques of regulation. Pre-litigation steps are covered; coercive investigatory powers examined; and the limitations imposed by privilege discussed.
