Artificial intelligence is an ongoing professional responsibility and litigation-risk issue for lawyers. The California State Bar recently published new guidance. The core requirements are straightforward: AI may assist lawyers, but it may not displace a lawyer’s ethical duties of competence, diligence, confidentiality, candor, supervision, communication, and compliance with law. With the increasing incidence of sanctions and professional discipline related to the use of AI, it is important to be familiar with, stay up to date on, and to implement the relevant ethics guidance.

The Fifth Circuit's en banc decision in Sterling v. City of Jackson tests whether residents exposed to lead-contaminated municipal drinking water can sue under Section 1983 for substantive due process violations.
