All In: Embedding AI in the Law School Classroom

What is the irreducibly human element in legal education when AI can pass the bar exam, generate effective lectures, and provide personalized learning and academic support? This article by law professor Gregory M. Duhl confronts that question head-on by documenting the planning and design of a comprehensive transformation of a required doctrinal law school course—first-year Contracts— with AI fully embedded throughout the course design. Instead of adding AI exercises to conventional pedagogy or creating a stand-alone AI course, this approach reimagines legal education for the AI era by integrating AI as a learning enhancer rather than a threat to be managed. The transformation serves Mitchell Hamline School of Law’s access-driven mission: AI helps create equity for diverse learners, prepares practice-ready professionals for legal practice transformed by AI, and shifts the institutional narrative from policing technology use to leveraging it pedagogically.

2023 Developments in Legal AI and the Courts

Jocelyn Stilwell-Tong, Law Librarian, California Court of Appeal, Sixth Appellate District, has determined that although free AI online is useful, the developing products from major legal research platforms show great promise. These paid products control for issues like hallucinations, and provide citations supporting their work so a researcher can confirm the accuracy and context of the materials the AI is pulling from. Issues surrounding data governance (what the company does with your uploaded material and search history) can be controlled by contract, and the legal vendors understand that this is a concern for most legal clients.

The Case For Large Language Model Optimism in Legal Research From A Law & Technology Librarian

The emergence of Large Language Models (LLMs) in legal research signifies a transformative shift. This article by Sean Harrington critically evaluates the advent and fine-tuning of Law-Specific LLMs, such as those offered by Casetext, Westlaw, and Lexis. Unlike generalized models, these specialized LLMs draw from databases enriched with authoritative legal resources, ensuring accuracy and relevance. Harrington highlights the importance of advanced prompting techniques and the innovative utilization of embeddings and vector databases, which enable semantic searching, a critical aspect in retrieving nuanced legal information. Furthermore, the article addresses the ‘Black Box Problem’ and explores remedies for transparency. It also discusses the potential of crowdsourcing secondary materials as a means to democratize legal knowledge. In conclusion, this article emphasizes that Law-Specific LLMs, with proper development and ethical considerations, can revolutionize legal research and practice, while calling for active engagement from the legal community in shaping this emerging technology.

Finding People Resources and Sites 2022

This guide by Marcus Zillman identifies a wide range of free and fee based resources from which to choose to conduct people searches as well as brand and company reputation research, for business or personal reasons. It is important to note that the largest and most prominent data aggregators resell their content to other sites. In addition, data on free and some fee based sites may not be cleansed and can include inaccuracies that range from minor to critical. Also, many sites offer free search but charge a fee to review the results. It is therefore advisable to use multiple sources in your research and compare and contrast results before pursuing the use of these data.

His precise and expert review of the site, accompanied by relevant screen shots, is a must read guide for legal researchers as they consider whether to transition to this new platform.

But the added features that I described above — Search Tree, Missing and Must Include, Search Term Maps, and Ravel View — are valuable in that they give researchers more control over their searches and results without requiring them to be power researchers.”
