The dramatic growth of medical malpractice litigation in recent decades has contributed significantly to an overall increase in health care costs in this country. Although lawmakers, physicians, and other responsible citizens have proposed numerous solutions in an effort to curb the crisis, these proposals have generally been ineffective. In this Article the Author endorses countersuits as the most appropriate response to frivolous medical malpractice actions. The Author also suggests that contingent fee systems, coupled with the economic motivation of private insurers to settle claims quickly, provide incentive for plaintiffs to initiate frivolous claims. This Article analyzes the general legal approaches available for countersuits, emphasizing recent successful actions based on malicious prosecution and abuse of process, and proposes more widespread use of these approaches.
