Federal Judges Embrace AI Tools in Widespread Adoption

A recent study from Northwestern University highlights the growing role of artificial intelligence in the federal judicial system. Conducted among federal judges, the survey reveals that over 60% of judges are utilizing AI tools in their judicial duties.

Study Overview

Led by Daniel Linna, a senior lecturer at Northwestern Pritzker Law, and V.S. Subrahmanian, a professor at McCormick School of Engineering, the research involved a stratified random sample. It included 502 federal judges, covering various tiers of the judiciary such as bankruptcy, magistrate, district, and appellate judges. The data was collected from December 2 to December 19, 2025, and aimed to assess the use and perspectives on AI’s role within the courts.

Key Findings

• Over 60% of judges reported using at least one AI tool.
• Only 22.4% of judges use these tools on a daily or weekly basis.
• 38% have never used any AI tools in their work.

The survey included questions on various AI tools such as ChatGPT, Claude, Copilot, and several legal-specific applications including CoCounsel and Westlaw AI. Legal research emerged as the primary use case for AI tools among judges, constituting 30% of reported usage, followed by document review at 15.5%.

Judge Perspectives on AI

While many judges see potential in AI for enhancing access to justice, there is also caution about its implications. Linna noted that understanding how to integrate AI into the judiciary safely and effectively is crucial. Currently, many judges express optimism mixed with concern regarding AI’s impact on their work.

• 45.5% of judges reported lacking AI training from court administration.
• Only 33.3% permit or encourage AI usage in their chambers.
• Approximately 20% have formal prohibitions on AI use.

Future Directions

The researchers emphasize the importance of training and policy development regarding AI tools in the courts. They aim to conduct further studies to enhance understanding and inform best practices for judicial AI usage.

With AI’s growing presence, Linna and Subrahmanian underscore the importance of proactive measures. Judges and legal professionals should spearhead efforts to ensure AI applications promote justice and uphold the rule of law. This study serves as a critical starting point for evaluating AI’s integration into the federal judiciary.
