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).

The AI Knows Too Much: When Employees Feed Trade Secrets into Generative AI Tools

April 14, 2026 — Kazim A. Naqvi & John V. Mysliwiec - Sheppard
Every time an employee pastes proprietary source code, a customer list, or a confidential business strategy into ChatGPT, Claude, or Google Gemini, they may be quietly dismantling the legal protections that make those secrets worth protecting. Courts and regulators are only beginning to grapple with this problem, and right now, the burden of preventing it falls squarely on employers. The Legal Stakes Under the federal Defend Trade Secrets Act (“DTSA”) and the Uniform Trade Secrets Act (“UTSA”) as adopted across most states, a trade secret plaintiff must show that the information at issue was subject to reasonable measures to maintain its secrecy. Courts have historically credited measures like confidentiality agreements, physical access controls, and employee training—but those safeguards were designed for a world of thumb drives and disgruntled employees. They were not built for a world where a well-meaning engineer can, in seconds, transmit an entire corpus of proprietary data to a third-party AI platform operating under terms of service that may permit the provider to use inputs for model training.

Supreme Court Rules Tariffs Unconstitutional: Why the Construction Industry Shouldn’t Expect Calm Just Yet

March 31, 2026 — Christopher Barnett - Construction Executive
The U.S. Supreme Court’s 6–3 decision in Learning Resources, Inc. v. Trump did what many expected: It held that the International Emergency Economic Powers Act (IEEPA) does not authorize the President to impose tariffs. What few anticipated was the speed of what followed: Within hours of the ruling, the administration announced replacement tariffs under Section 122 of the Trade Act of 1974, imposed a 10% global surcharge effective February 24, and signaled forthcoming Section 301 investigations against most major trading partners. For those in the construction industry hoping the Learning Resources ruling would restore market stability, the message was unambiguous. The constitutional question may be settled, but the market disruption is not. Reprinted courtesy of Christopher Barnett, Construction Executive, a publication of Associated Builders and Contractors.

DOI Finalizes Long-Awaited Modernization of Type A Natural Resource Damage Assessment Regulations

August 03, 2026 — Amanda G. Halter, Ashleigh K. Myers & Jillian Marullo - Gravel2Gavel Construction & Real Estate Law Blog
For nearly three decades, the U.S. Department of the Interior’s (DOI) simplified “Type A” Natural Resource Damage Assessment (NRDA) regulations were available more in theory than in practice, constrained by dated models, narrow geographic applicability and a $100,000 cap that rarely matched the economics of modern environmental claims. DOI has now finalized revisions to the Type A natural resource damages assessment procedures under 43 C.F.R. Part 11 for hazardous substance releases under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) and the Clean Water Act (CWA), with the final rule published in the Federal Register on July 13, 2026 and scheduled to become effective August 12, 2026. As discussed previously, DOI has sought to modernize what it views as an “inefficient and inflexible” process and restore the Type A procedure to its intended role as a more streamlined pathway for smaller, less contentious NRD claims. The final rule adopts a $5 million default damages threshold, allows use above that amount if all parties agree, clarifies that Type A may be used in all environments and for all natural resource types, and removes legacy model appendices that had tethered the process to outdated formulas.

Agent Not Liable for Loss Given Insured’s Vague Instructions for Coverage

April 08, 2026 — Tred R. Eyerly - Insurance Law Hawaii
The Illinois Appellate Court affirmed the district court’s grant of summary judgment to the insured’s agent because there was no breach of duty. Jon Van Order v. Hauk, et al., 2025 Ill. App. Unpub. LEXIS 2378 (Ill. Ct. App. Dec. 23, 2025). The insured began renovating a vacant home in October 2018. He met with agent Joseph Hauk and explained the property was vacant and would be going through renovations for the next several months. Hauk then procured a policy through Shelter Insurance Company insuring the vacant property against several specified perils. The policy provided coverage for water damage if “[t]he exterior of the building sustained a covered loss” and “that loss created an opening through which the water entered.” Damage caused by escaping water from within a plumbing system was excluded if: (1) the damage was caused by a “continuous or repeated leakage over a period of fourteen days or more” or (2) the insured premises had been vacant for 30 consecutive days immediately preceding the loss.

The GKN Aerospace Chemical Release and the Laws Designed to Address It

July 06, 2026 — Sean M. Sherlock - Snell & Wilmer
On May 21, 2026, a 34,000-gallon storage tank at the GKN Aerospace facility in Garden Grove, California began leaking methyl methacrylate (MMA), a volatile and highly flammable industrial chemical used to manufacture high-strength acrylic plastics. GKN Aerospace makes advanced military and commercial transparencies, such as aircraft canopies, windshields, cabin windows, bullet-resistant glass, and spacecraft windows. In polymer chemistry lingo, MMA is known as a monomer. Monomers are like individual links to a chain. Under the right conditions they link up (react) with each other to form long-chained polymers, or plastics. MMA is an unstable monomer that requires controlled storage conditions to avoid setting off a polymerization (chain) reaction. According to early reports, the MMA tank at GKN Aerospace overheated. The cause of the overheating is not yet clear, but the overheating may have created conditions enabling the MMA to initiate polymerization, which in turn generated heat, which in turn generated pressure, activating the tank’s pressure-relief system and releasing MMA vapor into the atmosphere. Concerns about a runaway reaction, massive release, and explosion led the Orange County Fire Authority to order evacuation of approximately 40,000 residents and closure of thirteen schools.
