We have published the second briefing in a two-part series examining the intersection of artificial intelligence (AI) and legal professional privilege in the context of investigations. Part 1 in this series addressed: (i) a recap on key privilege principles and their interaction with generative AI tools; and (ii) privilege considerations arising in internal firm-led reviews and investigations, including in relation to document collation and review, AI-generated outputs, board reporting and the use of AI transcription tools. In Part 2, we address: (i) privilege risks when responding to Financial Conduct Authority regulatory inquiries and investigations; and (ii) practical implications and recommendations for firms.
