Since the advent of legal reporting, citations have faced few challenges as significant as those posed by recent developments in artificial intelligence. This development was brought into sharp focus by the release of The Bluebook’s 22nd edition, which introduced Rule 18.3, a guideline for citing generative AI content. Designed to address new forms of digital content, the rule has nonetheless faced substantial criticism from legal scholars and practitioners.
Legal professionals like Cullen O’Keefe, Director of Research at the Institute for Law & AI, have expressed concerns that this rule lacks the precision for which The Bluebook is known. Meanwhile, Susan Tanner from the University of Louisville forthrightly described the rule as “bonkers” in her critique published on Medium.
Rule 18.3 categorizes citations into subsections: large language models, AI-powered search results, and non-textual AI content, each with specific requirements. For AI large language models, citations must include prompt authors, model names, exact text of the prompt, dates, and where the outputs are stored as PDFs. This specificity, however, has been met with criticism for its complexity and its burden on legal professionals, many of whom lack the necessary technical proficiency.
The rule also fails to clarify when citing AI is appropriate, leaving legal professionals questioning whether such citations reflect reliance on AI-generated authority or simply its use as a tool. Jessica R. Gunder of the University of Idaho College of Law further argues that this lack of clarity could lead to ethical issues, such as breaching client confidentiality when prompts involve sensitive information.
The criticisms emphasize not only the structural inconsistencies within Rule 18.3 but also highlight a fundamental misunderstanding of AI’s role in legal research and writing. As AI increasingly becomes integral to legal practices, these insights suggest a need for The Bluebook’s editors to reconsider and possibly revise the rule to align more accurately with the realities of AI usage in modern legal contexts.
