U.S. Supreme Court Decision Alters Course of $745M Louisiana Coastal Damage Judgment

June 15, 2026 — Jennifer Kretschmann & Jennifer E. Michel - Lewis Brisbois
The U.S. Supreme Court has issued a unanimous decision allowing oil and gas companies to move Louisiana coastal erosion lawsuits from state court to federal court under the federal officer removal statute. While the ruling is procedural, it carries significant implications for environmental- and energy-related risks. The case, Chevron U.S.A. Inc. v. Plaquemines Parish, Louisiana, Slip Op. 24-813 (April 17, 2026), addressed a threshold jurisdictional question but has broader significance for environmental and climate related litigation. State courts are often viewed as more favorable forums for plaintiffs asserting environmental damage claims, particularly those brought by governmental entities. The opinion issued on April 17, 2026 is the latest development in long-running Louisiana coastal litigation that began more than a decade ago. Starting in 2013, Louisiana parishes filed 42 lawsuits against oil and gas companies alleging environmental damage related to historic oil field operations. The parishes alleged that oil and gas companies violated state coastal management laws by failing to properly restore impacted areas. Chevron sought to remove the cases from state court under 28 U.S.C. § 1442(a)(1), known as federal officer removal, which provides federal jurisdiction over “any person acting under [an] officer” of the United States "for or relating to any act under color of such office." The Fifth Circuit rejected the argument and remanded the case, and others like it, to state court. Trial began in March 2025 in Point à la Hache, Louisiana. On April 4, 2025, the jury awarded a total of $745 million to compensate for land loss, contamination and abandoned equipment. On June 16, 2025, the U.S. Supreme Court agreed to review the question of whether a federal contractor can remove to federal court when sued for oil-production activities undertaken to fulfill a federal oil-refinement contract.

LA Scores Major Victory in a High-Exposure Premises Liability Action

July 06, 2026 — Dolores Montoya - Bremer Whyte Brown & O'Meara LLP
Our firm is proud to announce a decisive defense victory obtained by Partner Daniel Crespo and Associate Lauren Landau for our client in a high-exposure premises liability action arising from a 2022 incident at an active school construction site in Perris, California. On March 10, 2026, the Riverside County Superior Court granted Summary Judgment in full for our client, dismissing all claims brought by Plaintiff, who alleged she tripped and fell over a curb while picking up her daughter from school and sustained ankle and wrist injuries as a result. Through meticulous preparation and the strategic use of construction plans, contractual documents, and onsite surveillance video evidence, our team demonstrated that our client had no ownership, possession, or control over the portion of the existing sidewalk where the incident occurred, with construction plans unambiguously designating the area as pre-existing concrete outside our client’s scope of work, and the Construction Services Agreement expressly reserving control over all existing site improvements to the school district.

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.

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.

Seattle’s Residential Zoning Transformation: What Property Owners, Buyers, and Investors Should Understand

May 14, 2026 — Lawrence S. Glosser - Ahlers Cressman & Sleight PLLC
Seattle is in the midst of a significant transformation in residential land use policy. Longstanding neighborhood zoning patterns that historically favored detached single-family development are being reexamined in response to housing supply pressures, affordability concerns, and evolving state mandates. For homeowners, purchasers, investors, and builders, these changes may create substantial new opportunities. They also create a heightened need for careful legal and practical due diligence. While zoning reform can expand potential uses of property, it does not eliminate the many other constraints that may still govern what can actually be built. Read the full story...
