Risks of Using an AI Chatbot for Legal Advice: Lessons from United States v. Heppner

April 08, 2026 — Payne & Fears LLP
Imagine that you are an executive (who is not a lawyer) and are concerned about what your company plans to do is legal. You could call your lawyer who might bill you for the call. Or, you can ask your AI chatbot, such as Claude or ChatGPT, about the legal risk. The chatbot will likely compliment you on the incisive question, provide you with highly confident answer (that may or may not be right) and will not bill you on an hourly basis. That is essentially what financial services executive Bradley Heppner did. It did not end well. A federal court recently ruled that Heppner’s chats with the AI tool Claude were not protected by attorney-client privilege or the work-product doctrine. That means that the other side (in this case, the federal government) could get access to his chatbot prompts, uploads and responses, and learn a great deal about, for example, whether Heppner knew what he was doing was illegal.

Jurisdiction Over Foreign Manufacturers in Construction Litigation

May 14, 2026 — Timothy J. Repass & Miki J. Saito - Wood Smith Henning Berman
A recent decision from the Washington Court of Appeals provides important guidance on personal jurisdiction over foreign product manufacturers in construction and infrastructure litigation. In King County v. Aquatherm GmbH, No. 85572-7-I (Wash.Ct. App.Div.I)(unpublished), the court addressed whether a German manufacturer could be sued in Washington for alleged defects in piping used in major public infrastructure projects. The ruling offers a detailed, fact-driven roadmap for how Washington courts evaluate jurisdiction over foreign manufacturers operating through layered distribution networks. It also reflects a broader trend toward focusing on real-world commercial conduct rather than formal corporate structure. Background of the Case King County sued after widespread failures in polypropylene piping installed at the King County Correctional Facility. The pipe, manufactured by Aquatherm GmbH in Germany, was marketed, distributed, and installed through a network of U.S.-based entities. Following a six-week trial, the jury returned a verdict exceeding $18 million on claims under the Washington Product Liability Act and Consumer Protection Act. Aquatherm challenged, among other things, the trial court's exercise of personal jurisdiction. Reprinted courtesy of Timothy J. Repass, Wood Smith Henning Berman and Miki J.

Ninth Circuit Holds That Policies Covering Environmental Claims Do Not Have Aggregate Limits

May 12, 2026 — Lorelie S. Masters & Joseph T. Niczky - Hunton Insurance Recovery Blog
In the case of County of San Bernardino v. Insurance Company of the State of Pennsylvania, the Ninth Circuit recently addressed the issue of whether general liability policies issued in the 1960s and 1970s included aggregate limits for claims arising under the premises-operations coverage in CGL policies. The difference between the policyholder’s interpretation of the policies’ limits clauses and the insurer’s interpretation was worth hundreds of millions of dollars in exposure for the insurer. The Court closely examined the policy language and extrinsic evidence from both the insurance industry’s drafting history and the parties before concluding that the policies were ambiguous. The Court construed that ambiguity in favor of the policyholder and ruled that aggregate limits did not apply to the claims at issue. The Court’s decision underscores the importance of carefully examining a policy’s limits, especially for older policies written before 1986 when the insurance industry revised the standard-form CGL policy to state the aggregate limits apply not only to products liability claims but to premises-operations claims as well. Decades of insurance industry drafting history confirms, as the policyholder’s submissions in this case indicate, that the industry well understood that operations claims like the environmental waste-disposal claims at issue here typically were not subject to aggregate limits.

The Firm Turns 16!

July 20, 2026 — Christopher G. Hill - Construction Law Musings
I have always found it appropriate that my jump to solo practice and Independence Day are so close in time. Today marks the 16th anniversary of my first day as a solo practitioner of construction law at The Law Office of Christopher G. Hill, PC. Time sure has flown by thanks to the great clients and friends who followed me to solo practice and whom I have met since the firm’s founding on July 1, 2010. I also could not have made the transition and had the fun and success I have enjoyed over the past 16 years without the support of the best wife and family that any construction lawyer could want. Since the firm’s last anniversary, my youngest child (who was 7 when this journey began!) has graduated from N. C. State University with a fisheries and wildlife biology degree and is currently in Casper, Wyoming working for Wyoming Game & Fish, my second oldest is an assistant director of admissions at Appalachian State University in Boone, NC, and has celebrated his second wedding anniversary, and my oldest has celebrated her fifth marriage anniversary. Our home in Captiva, Florida continues its recovery from from Hurricane Ian and subsequent hurricanes. Read the full story...

Supreme Court Strikes Down IEEPA Tariffs: The Refund Process Will Be Messy

March 10, 2026 — Brett W. Johnson, Derek Flint, T. Troy Galan & Thomas Williams - Snell & Wilmer
On February 20, 2026, the U.S. Supreme Court held in Learning Resources, Inc. v. Trump, and the consolidated case Trump v. V.O.S. Selections, Inc., that the International Emergency Economic Powers Act (IEEPA) does not authorize the President to impose tariffs unilaterally.1 The decision invalidates both the “reciprocal” tariffs and the drug-trafficking tariffs imposed under IEEPA. For importers, the immediate question is whether, how, and when refunds can actually be obtained. On that issue, the U.S. Supreme Court provided no roadmap. To the contrary, the dissent warned that the United States “may be required to refund billions of dollars,” that the process is likely to be a “mess,” and that the majority opinion “says nothing today about whether, and if so how, the Government should go about returning the billions of dollars that it has collected from importers.” Reprinted courtesy of Brett W.
