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.

Settlement Agreements and Contracts Require a Meeting of the Minds

July 20, 2026 — David Adelstein - Florida Construction Legal Updates
A settlement agreement does not need to be executed for it to be enforceable as long as there was a MEETING OF THE MINDS. The same rings true for any contract regardless of whether the contract is signed – THERE NEEDS TO BE A MEETING OF THE MINDS. In a recent case dealing with the settlement agreement on a construction lien, the essential settlement terms (money and mutual release) were memorialized in an e-mail exchange between the parties (owner and subcontractor). The settlement required the owner to pay the principal amount plus some attorney’s fees and then a mutual general release would be prepared. In response to the confirmatory email, the owner sent a check, which the subcontractor deposited, but the owner refused to sign the release signed and sent by the subcontractor. The owner further claimed it doesn’t need to pay the attorney’s fees because the lien amount was paid in full. The subcontractor sued arguing the owner breached the terms of the settlement. The appellate court agreed. Read the full story...

Doctrine of Substantial Performance When It Comes to Payment

July 27, 2026 — David Adelstein - Florida Construction Legal Updates
A recent non-construction case touches upon the doctrine of substantial performance when it comes to payment. In this case, a club was to make two payments to secure a rapper’s attendance. The first payment was made. The second payment was made but was a few hundred dollars short of the agreed amount. The rapper did not show up. The club claimed it substantially performed its obligations. At first glance, the argument makes sense because the second payment fell only a few hundred dollars short. But that wasn’t the case when it comes to pre-commencement payment obligations:

Substantial performance applies only when the variance from the contract terms “is inadvertent or unintentional and unimportant so that the work actually performed is substantially what was called for in the contract.” However, when one party agrees to pay the other on or before a specific date, time is of the essence, and the payor is required to pay the payee on or before that date. “There is almost always no such thing as ‘substantial performance’ of payment between commercial parties when the duty is simply the general one to pay. Payment is either made in the amount and on the date due, or it is not.”

Big Gate Records, LLC v. Washington, 51 Fla.L.Weekly D1281a (Fla. 2nd DCA 2026) (internal citations omitted).

For Urban Walkers, a Patchy Dilemma: Who Owns the Sidewalk?

July 06, 2026 — Linda Poon – Bloomberg
In 2007, New York City’s sanitation department threatened Natalie Shea with a $300 fine for defacing public property with graffiti. Her crime: drawing a blue flower in front of her family’s Park Slope home with sidewalk chalk. She was six years old. The incident, which made local and national news at the time, captures the fraught role that sidewalks often play in US cities. These patches of pavement do more than carry pedestrians to their destinations: They’re also places for commerce, social interaction and childhood play, from chalking to learning how to ride a bike. Urbanist Jane Jacobs once likened the range of activities that city sidewalks attract to an “intricate ballet.” In the new book Sidewalk Nation: The Life and Law of America’s Most Overlooked Resource (Harvard University Press), author Michael Pollack explores the “tangled web of state and local regulation” that governs sidewalks, with cities often passing along responsibilities for tasks like clearing snow and keeping walkways safe. He paints a portrait of the American sidewalk a disorderly and often neglected network, filled with literal and metaphorical cracks that give rise to all sorts of conflict, from mundane clashes over maintenance to more consequential fights over accessibility and inequality.

A Permitting Base Checklist for Data Centers and Power Plants

June 02, 2026 — Michael S. McDonough, Stephen J. Humes & Stacey C. Wright - Gravel2Gavel Construction & Real Estate Law Blog
There is a lot of talk these days about “license to operate” for data centers, meaning management of the relationships with stakeholders and broader communities concerning both the benefits and adverse consequences of locating a facility in a particular locale. Here, we are speaking of “license to operate” more literally—namely, the legal and regulatory permitting and approval requirements for a privately owned data center whether by itself or colocated with a power generating plant. Our Base Checklist includes generally and potentially applicable permitting requirements for development and operation, using California as an example. (Taking legal authority Frank Sinatra out of context, “If you can make it there, you can make it anywhere.”) The actual requirements for a given facility would depend, in part, on local law, including planning and zoning laws and plans, and the environment of the site. Just as examples, additional permitting and mitigation requirements might apply if sensitive receptors are located nearby (e.g., noise mitigation for residential dwellings), if sensitive and protected biological resources (e.g., jurisdictional waters and/or protected species) would be impacted, or if the present or former land uses require additional measures (e.g., hazardous materials remediation, mitigation for conversion of prime farmland, or protection of cultural resources). The scope of permit requirements would ultimately be determined by the applicable regulatory agencies and by the lead and responsible agencies under the applicable state environmental land use regime—in our reference case here, the California Environmental Quality Act (CEQA).

2026 Construction Outlook: Dampening Outlook With Some Potential Bright Spots

February 17, 2026 — Garret Murai - California Construction Law Blog
According to Dodge Construction Network’s Outlook 2026 Ebook, “the construction industry came roaring into 2025” – with large government investments through the Infrastructure Bill and the CHIPS Act (promoting investment in the domestic semiconductor industry), as well as outsized spending on data centers to support cloud and AI technology – but “throttled back significantly” due to “rapid changes to economic and fiscal policies.” These changes include short-term cost impacts due to tariffs and labor impacts due to the federal government’s immigration crackdown and long-term concerns following enactment of the One Big Beautiful Bill (OBBBA) which is anticipated to add $3.4 trillion to the federal deficit over ten years.
