Federal Court Highlights the Strategic Value of Additional Insured Coverage

June 22, 2026 — Michael S. Levine - Hunton Insurance Recovery Blog
A recent decision from the District of Maryland underscores a recurring—but often underutilized—opportunity for policyholders: securing and enforcing additional insured coverage under another party’s liability policy. In Charter Oak Fire Insurance Co. v. Builders Premier Insurance Co., the court held that an equipment lessor qualified as an additional insured under the lessee’s policy and was entitled to a primary defense. The decision is a useful reminder that additional insured coverage can fundamentally shift defense obligations and materially reduce a policyholder’s exposure. We build on the decision to highlight the practical steps policyholders should take to ensure that all potentially available insurance is identified and pursued. Read the full story...

Understanding the EPA’s Latest Proposed Drinking Water Contaminant Monitoring Rule, Published in Law360

September 01, 2026 — Gordon Rees Scully Mansukhani
The U.S. Environmental Protection Agency’s (EPA) proposed Sixth Unregulated Contaminant Monitoring Rule (UCMR 6) represents another step in the federal government’s ongoing effort to identify and evaluate emerging contaminants in drinking water. The proposal would require certain public water systems to monitor and report on 30 unregulated drinking water contaminants from 2028 through 2030, while generating occurrence data that could inform future regulation and affect environmental, commercial, litigation and risk assessments. In an article published by Law360, Gordon Rees Scully Mansukhani Senior Counsel, Ayodeji Ayolola, analyzes the scope and practical implications of UCMR 6, including the contaminants selected, the proposed monitoring requirements for public water systems, and the EPA’s continued focus on PFAS and related organofluorine compounds. The article also touches upon the potential significance of publicly available monitoring data for businesses and property stakeholders. Read the full story...

EPA Expands PFAS Reporting Requirements with Addition of New Chemical to Toxics Release Inventory, Published by Law360

June 08, 2026 — Gordon Rees Scully Mansukhani
The U.S. Environmental Protection Agency’s (EPA) addition of sodium perfluorohexanesulfonate (PFHxS-Na) to the Toxics Release Inventory (TRI) introduces new federal reporting requirements for businesses that manufacture, process, or use the chemical. Because reporting obligations apply retroactively to the start of the year, affected facilities must quickly evaluate their compliance and recordkeeping practices. In a recent Law360 article, Gordon Rees Scully Mansukhani Senior Counsel, Ayodeji Ayolola, explains why PFHxS-Na was automatically added to the TRI, how the EPA’s public reporting system works, and which businesses may be affected by the new rule. The article also touches upon key compliance considerations, including supply chain reviews, reporting thresholds for chemicals of special concern, and preparation for public disclosure requirements.

The “Pay When Paid” Clause in California Construction—Strategies as the Battle Continues

August 03, 2026 — William L. Porter - Porter Law Group
It is well known in California Construction circles that the “Pay If Paid” clause is illegal in this state. There is a great distinction, though, between this clause and a similar clause, known as a “Pay When Paid” clause. A pay if paid clause allows a contractor to tell a subcontractor that if the contractor is unpaid for the subcontractor’s work, then the contractor has no legal obligation to pay the subcontractor, ever. For a great variety of reasons, the California Supreme Court, in the case of Wm. R. Clarke Corp v. Safeco Ins. Co. of America (1997) 15 Cal.4th 882, declared this type of clause illegal in California Construction. Although the pay if paid clause is illegal in California, the pay when paid clause is still perfectly legal and is found in many subcontracts that contractors issue to their subcontractors. The pay when paid clause allows a contractor to delay paying its subcontractors until the dispute between the contractor and the property owner over payment has been resolved and the contractor is paid by the property owner. Although seemingly reasonable (since it merely delays payment until the contractor is paid by the owner, thereby providing a funding source to pay subcontractors), significant problems still arise.

Kahana Feld Obtains Favorable Result in High-Exposure NY Premises Liability Case

June 15, 2026 — Leigh Katz - Kahana Feld
Kahana Feld partner Leigh Katz obtained a significant victory in a recent matter involving a videotaped alleged trip and fall on the sidewalk in front of the client’s commercial residence. The plaintiff claimed he suffered a knee injury that necessitated surgery, along with other assorted injuries that prevented him from continuing high-level athletic activities. Leigh was able to demonstrate that the fall was staged and received a voluntary discontinuance with prejudice. At mediation, Leigh emphasized that KF’s expert witness challenged the plaintiff’s claim that the fall was caused by a sidewalk height differential after reviewing the videotape footage and determining the plaintiff’s fall began before his feet made contact with the alleged defect. Based on this analysis, the expert concluded the reported height differential did not initiate the fall, which supported KF’s position that the incident depicted in the video was unrealistic and appeared staged.

New York Climate Superfund Rulings Put Vermont Law in Focus

October 20, 2026 — Amanda G. Halter, Ashleigh K. Myers, Jillian Marullo & Marcus Manca - Pillsbury
A second federal judge has struck down New York’s Climate Change Superfund Act and barred its enforcement. On September 23, 2026, Judge P. Kevin Castel of the U.S. District Court for the Southern District of New York issued a decision granting summary judgment to the United States and the U.S. Environmental Protection Agency (EPA), declaring the Act unconstitutional, and permanently enjoining New York officials from enforcing it in United States v. New York, No. 1:25-cv-03656 (S.D.N.Y. Sept. 23, 2026). Judge Castel’s decision closely tracks the Northern District of New York’s August 31 decision in West Virginia v. James, Case No. 1:25-cv-00168 (N.D.N.Y. Aug. 31, 2026). Both courts held that the Clean Air Act (CAA) preempts New York’s effort to impose strict liability through a climate attribution and cost recovery framework based on interstate greenhouse gas (GHG) emissions. Both also held that the foreign affairs doctrine preempts the Act as applied to fossil fuel activity outside the United States. On September 24, the Northern District entered Rule 54(b) judgment implementing its August 31 decision, enjoining Attorney General Letitia James and DEC Commissioner Amanda Lefton from implementing or enforcing the Act and permitting an immediate appeal of the preemption claims.
