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.

Defend Now, Allocate Later? An Unresolved Tension in Colorado Construction Law

August 16, 2026 — David McLain - Colorado Construction Litigation Blog
For decades, Colorado law has recognized an important distinction between the duty to defend and the duty to indemnify. The former ordinarily arises at the beginning of litigation; the latter generally cannot be determined until the underlying liability is known. That distinction makes intuitive sense. A defense that becomes due only after litigation concludes is not much of a defense. But Colorado’s construction anti-indemnity statute, C.R.S. § 13-21-111.5(6), raises an interesting question about how that familiar rule operates in construction disputes. The statute expressly regulates contractual obligations not only to indemnify, but also to insure and defend, and it reflects a legislative policy that construction businesses should bear financial responsibility for their own negligence. Those principles have developed along separate tracks. At some point, a Colorado appellate court may have to decide precisely how they fit together. Read the full story...

From CERCLA to Drinking Water: D.C. Circuit’s PFAS Ruling Enters a Second Regulatory Fight

October 06, 2026 — Ashleigh K. Myers, Amanda G. Halter & Jillian Marullo - Gravel2Gavel Construction & Real Estate Law Blog
On August 18, 2026, a unanimous panel of the U.S. Court of Appeals for the D.C. Circuit upheld EPA’s designation of perfluorooctanoic acid (PFOA) and perfluorooctanesulfonic acid (PFOS) as hazardous substances under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA or Superfund). In Chamber of Commerce of the United States v. EPA, the court rejected challenges to EPA’s interpretation of CERCLA Section 102(a), the adequacy of its notice and comment process, its analysis of costs and benefits, and its decision to proceed despite uncertainty about future response actions and costs. This decision is already being invoked in a separate D.C. Circuit challenge to EPA’s 2024 PFAS drinking water rule promulgated under the Safe Drinking Water Act (SDWA). Six days after the CERCLA decision, respondent intervenors cited it as supplemental authority in American Water Works Association v. EPA, No. 24-1188, ahead of oral argument scheduled for September 18, 2026. The Chamber of Commerce decision may assist the respondent intervenors on certain notice and comment and economic analysis arguments, but its significance should not be overstated. The principal challenges to the standards for the four PFAS subject to EPA’s Hazard Index-based maximum contaminant level (MCL) turn on requirements specific to the SDWA, and EPA itself now agrees that those provisions were promulgated through an unlawful process.

Building in Arizona’s Data Center Boom: How Federal Executive Orders, State Regulation, and National-Security Policy Are Reshaping the Rules for Developers

June 02, 2026 — Ryan J. Regula - Snell & Wilmer
Developers and practitioners evaluating data center projects in Arizona face a regulatory environment shifting on three fronts simultaneously. Federal executive orders are opening new land, streamlining permitting, and channeling financial incentives toward qualifying projects — but they are not preempting the state and local rules that most directly affect project economics. A carve-out in the December 2025 Artificial Intelligence (AI) Framework Executive Order preserves Arizona’s authority over data center infrastructure, meaning the Arizona Corporation Commission’s (ACC) rate-classification docket, municipal zoning restrictions, water-use ordinances, and pending grid cost-allocation legislation remain the binding constraints on project feasibility. Understanding where federal tailwinds end and state and local headwinds begin is essential for any developer sizing risk or selecting sites in the state. The Federal Landscape: An Interlocking Framework of Executive Orders Five interlocking executive orders are accelerating data center development nationally, but none overrides Arizona’s authority over siting energy, or infrastructure.
