Principle and Policy in Malicious Prosecution

Judicial consideration by the Judicial Committee of the Privy Council, and the United Kingdom Supreme Court, of the tort of malicious prosecution – historically confined to criminal prosecution and limited civil proceedings – demonstrates considerable confusion in Common Law systems over the roles of principle and policy in judicial reasoning. As judgements extending malicious prosecution to maliciously motivated civil claims demonstrate, the principles and policies underpinning malicious prosecution and abuse of process, and the relationship between these torts – regarded by judges and jurists as anomalous – remain unclear. Other common law jurisdictions are yet to positively affirm the revised malicious prosecution tort’s applicability to civil proceedings, and the few plaintiffs to plead the expanded tort to date have been unsuccessful. While the harms arising from maliciously brought civil proceedings understandably excite sympathy, this article contends that expanding malicious prosecution to civil claims via common law reform is a problematic solution resting on unsound jurisprudential foundations, which faces potentially insurmountable evidentiary barriers and necessitates further litigation. We suggest that a better alternative is to encourage greater use of the court’s existing inherent jurisdiction to award compensatory costs and propose introduction of punitive statutory costs powers, available in extreme cases, to deter litigants from initiating civil claims prompted by malice.
