California continues to lead the nation in artificial intelligence (“AI”) regulation with the recent enactment of Senate Bill (“SB”) 53—the Transparency in Frontier Artificial Intelligence Act (“TFAIA” or the “Act”)[1]. Signed by Governor Gavin Newsom earlier this fall, the TFAIA takes effect January 1, 2026, and establishes significant oversight, accountability, and reporting requirements for advanced developers at the cutting edge of artificial intelligence. This law sets a framework for transparency and public safety, and is expected to set a nationwide precedent for future AI legislation to come.Continue Reading California Enacts SB 53: A Defining Step in Responsible AI Governance for Frontier AI Developers

On October 8, 2025, Governor Newsom signed the California Opt Me Out Act (the “Act”) into law, which expands on the California Consumer Privacy Act (“CCPA”). Most notably, the Act mandates that businesses developing or maintaining internet browsers must include functionalities enabling consumers to automatically communicate their preference to opt out of the sharing or selling of personal information. The functionalities must be readily accessible to consumers and must be “easy for a reasonable person to locate and configure,” which will spare consumers from the hardships of navigating oftentimes confusing mechanics to identify and enable opt outs.Continue Reading Opting Out of Web Tracking Has Never Been Easier in California

Healthcare organizations of every shape and size are rapidly expanding their use of artificial intelligence solutions from high-risk applications like clinical decision-support interventions, ambient listening, and charting to lower-risk administrative activities like automated patient communications and scheduling. While adoption is widespread and increasing in depth and breadth across the industry, not every healthcare organization has established governance around AI or a monitoring process for exploration and adoption of new tools – including those contemplating a sale of assets or equity. For buyers in healthcare mergers and acquisitions today, AI diligence needs to be a focus, given the potential risk of compliance and class action concerns related to high-risk AI solutions, particularly those that have any interaction with protected health information (“PHI”) regulated under the Health Insurance Portability and Accountability Act, as amended and pursuant to its implementing regulations (collectively, “HIPAA”).Continue Reading AI Due Diligence in Healthcare Transactions

California’s physician assistant (“PA”) practice landscape is set to undergo significant transformation following the enactment of California Assembly Bill 1501 (AB 1501), which was signed into law by Governor Newsom on October 1, 2025, and will take effect on January 1, 2026. Among its key provisions, AB 1501 extends the authority of the California Department of Consumer Affairs’ Physician Assistant Board (the “Board”) through January 1, 2030, increases the physician-to-PA supervision ratio from 1:4 to 1:8 in all settings, and directs the Board to study scope-of-practice structures—with input from stakeholders—to evaluate potential models from other states that could benefit California. These modernization efforts are designed to enhance healthcare access and better align PA practice with current workforce demands. This article summarizes the key reforms implemented by AB 1501 and offers guidance on how PAs and their practices can prepare for these new requirements.Continue Reading AB 1501 Becomes Law: How It Will Reshape California PA Practice

Effective January 1, 2026, the law represents a significant expansion of the authority of the California Office of Health Care Affordability (“OHCA”), which already has broad review power over transactions involving many different provider and payor entities.Continue Reading Governor Newsom Signs AB 1415 Expanding OHCA Oversight to Private Equity and MSOs
