Generative AI tools have found their way into the legal profession — sometimes with disastrous results. From lawyers sanctioned for citing nonexistent cases to filings riddled with “phantom precedent,” these incidents have captured headlines and prompted courts and bar associations to issue guidance. This CLE explores several high-profile examples where legal professionals relied on hallucinated case law, analyzes what went wrong in each instance, and extracts practical lessons for avoiding similar mistakes. Participants will learn how to identify and verify AI-generated citations, adopt effective risk-mitigation strategies, and implement workflow safeguards that preserve professional responsibility. The session closes with best practices and ethical considerations for integrating generative AI into research, drafting, and litigation support — helping attorneys harness these tools without risking sanctions or reputational harm.
