Scope of Products Requiring Proposition 65 Warnings in California Poised to Grow

February 23, 2026 — Brian M. Ledger & Chassen B. Palmer - Gordon Rees Scully Mansukhani
The scope of products to be drawn into the warning requirements under California’s Proposition 65 law may soon be growing. California’s Office of Environmental Health Hazard Assessment (OEHHA) requested information from the public on the reproductive toxicity of p,p’-bisphenol chemicals. OEHHA is the lead agency for the implementation of Proposition 65, formerly known as the Safe Drinking Water and Toxicity Enforcement Act of 1986. OEHHA’s request for information is a step toward regulators classifying all p,p’-bisphenol chemicals as reproductive toxicants under Proposition 65. California’s Proposition 65 Under Proposition 65, businesses are required to post clear and reasonable warnings before individuals are exposed to chemicals listed by the state of California as carcinogens or reproductive toxicants. To date, California has listed approximately 900 chemicals that fall under Proposition 65 regulation. Businesses may be held liable for up to $2,500 per violation per day. Proposition 65 can be enforced by public prosecutors (e.g., the California attorney general or district attorneys) or by private enforcers (known as “bounty hunters”). Reprinted courtesy of Brian M.

GRSM Secures Illinois Appellate Victory for Architectural Firm in Implied Warranty Dispute

May 14, 2026 — Gordon Rees Scully Mansukhani
Gordon Rees Scully Mansukhani Partner Jonathan Federman, Partner Thomas Cronin, and Senior Counsel Garrett Lee recently secured a victory in the Illinois Appellate Court, Fifth District, on behalf of the firm’s client, an architectural firm, in a liability dispute. The case arose following an entity’s purchase of a 111-unit building for use as an investment or rental property. The plaintiff made claims against the architect of the building, alleging that there were design defects that breached an implied warranty, as well as a negligence claim. GRSM argued that an architect could not be liable for implied warranties, particularly for an implied warranty which no Illinois court has ever recognized. GRSM further argued that Illinois law bars an architect from liability for negligence arising from a duty pursuant to contract under the economic loss doctrine. 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.

Arizona Court of Appeals Clarifies Homeowners Association Open Meeting Requirements

June 29, 2026 — Jill Casson Owen, Benjamin J. Hawkins & Stephen Wright - Snell & Wilmer
A Z N H Revocable Trust v. Sunland Springs Village Homeowners Association, No. 1 CA-CV 25-0424 (Ariz. Ct. App. Apr. 28, 2026) OVERVIEW The Arizona Court of Appeals issued an opinion clarifying how homeowners associations must conduct meetings under A.R.S. § 33-1804. The decision reinforces the legislative policy favoring transparency in association governance, bringing association meeting requirements more in line with the open meeting standards applicable to public bodies under A.R.S. § 38-431 et seq. (Arizona’s Open Meeting Law). KEY HOLDINGS 1. All Voting and Formal Actions Must Occur in Open Meetings The Court affirmed that association boards cannot vote or take formal action during closed (executive) sessions. Under A.R.S. § 33-1804(A), associations may close portions of meetings only for “consideration” of certain enumerated topics, such as legal advice, pending litigation, or personal/financial information about individual members. The Court interpreted “consideration” to mean discussion and deliberation, not voting. The Court noted that dictionaries define “consider” as “spending time thinking about a possibility” and “formulating an opinion,” which are processes that precede formal action. This interpretation mirrors how Arizona’s Open Meeting Law (A.R.S. § 38-431.03(D)) prohibits public bodies from voting in executive session.

Modular Construction’s Big Boom: New Risks Outpacing Standard Contracts in Industrial Projects

March 24, 2026 — Chad Theriot & Jack Mayo - Construction Executive
Modular construction is revolutionizing the construction industry, tackling labor shortages, sustainability goals and supply-chain challenges, with the global market for modular and prefabricated construction projected to reach over $200 billion by 2030. While residential builders have embraced modular’s speed and affordability, the greatest risks—and opportunities—are emerging in the industrial sector, where project scale and complexity demand new legal strategies. In 2023, Chad Theriot explored industrial and infrastructure applications of modular construction, addressing risks like offsite fabrication and integration complexities in his article, “The Rise of Modular Construction—Impacts for Consideration.” Since that time, modular construction has continued to experience significant advancements and has been increasingly adopted by contractors across a broad spectrum of industrial and commercial projects. As modular construction continues to reshape the industrial landscape, contractors and owners alike must be mindful of the legal implications associated with its use, specifically as it relates to liability and risk allocation, regulatory compliance, quality control and upstream factors such as transportation and intellectual property concerns.
