Following the 10th Circuit's April 21, 2026, decision affirming the disallowance of Liberty Global’s $2.4 billion deduction under the codified economic substance doctrine, I.R.C. § 7701(o), Liberty Global filed a petition for panel rehearing or rehearing en banc on June 5, 2026. That petition has since drawn significant amicus support from various industry groups representing large taxpayers, as discussed below.

On July 1, 2026, EPA proposed the sixth Unregulated Contaminant Monitoring Rule (UCMR 6), which will require public water systems (PWS) to monitor 30 unregulated contaminants — including certain PFAS chemicals — but not microplastics. For now, EPA is using other tools, such as the Contaminant Candidate List (CCL), to learn more about microplastics before requiring PWSs to monitor for them.

A recent enforcement action led by Minnesota Attorney General Keith Ellison along with a bipartisan coalition of state attorneys general signals an accelerating and coordinated crackdown on competitively sensitive information-sharing arrangements.

As schools, athletes, and other entities continue to navigate the boundaries of the House Settlement (In Re College Athlete NIL Litigation, No. 4:20-cv-03919-CW), at least one recent decision made clear a court’s position on what qualifies as an Associated Entity under the settlement. As noted previously, the College Sports Commission (CSC) sent out a rules reminder in January regarding Associated Entities. Under the House Settlement, these entities include those

RICO was built for the mob. But Congress gave trade secret victims access to it in 2016, and a recent U.S. Court of Appeals for the Fifth Circuit decision shows that access is real.

A Kansas federal court held that inconsistent enforcement of trade secret rights can defeat a claim under the Defend Trade Secrets Act (DTSA). In Edelman Financial Engines, LLC v. Mariner Wealth Advisors LLC, No. 2:23-cv-02515-HLT (D. Kan. June 5, 2026), the court applied a selective enforcement theory, holding that when a company does not consistently pursue legal remedies against similarly situated former employees, that inconsistency can be affirmative evidence that it failed to protect its trade secrets. While the selective enforcement theory has appeared in academic hypothetical discussions, the decision appears to be one of the clearest judicial applications of a “selective enforcement” theory in a trade secret case.

When the U.S. Court of Appeals for the Fifth Circuit vacated the FTC's Combating Auto Retail Scams (CARS) Rule in January 2025 on procedural grounds, some dealers may have interpreted the decision as a signal that federal regulatory pressure on the auto industry had eased. Recent developments make clear that such optimism was misplaced.

On May 27, 2026, the California State Assembly advanced AB 2564, which would prohibit surveillance pricing by retailers. Assemblymember Christopher Ward originally introduced AB 2564 on February 20, 2026, to “ensure that people are not being unfairly charged higher prices due to their actual or perceived characteristics.”

From June 11 to July 19, 2026, 16 cities across the United States, Mexico, and Canada will host the 2026 FIFA Men’s World Cup, the largest in history. For construction firms, vendors, and suppliers, this trinational event has presented a significant commercial opportunity. Yet, cross-border projects involving parties operating under three distinct legal systems — common law in the United States and Canada, and civil law in Mexico — also create fertile ground for commercial disputes. Given the scale, technical complexity, and commercial significance of the FIFA World Cup and all the projects surrounding it, disputes are often unavoidable. As companies navigate intricate contractual obligations across multiple jurisdictions, international arbitration may play a pivotal role in resolving conflicts tied to these major commercial undertakings.

The first applications to lift an automatic suspension under the Procurement Act 2023 (the Act) have recently been decided. In Parkingeye Limited v Velindre University NHS Trust & Anor [2026] EWHC 1019 (TCC), handed down on 1 May 2026, HHJ Keyser KC dismissed applications by two NHS contracting authorities to lift the suspension preventing them from concluding a car park management services contract. This is the first judicial consideration of the new test under section 102(2) of the Act.

The U.S. Court of Appeals for the Seventh Circuit recently vacated the U.S. Tax Court’s decision in Hyatt Hotels v. Commissioner, a case concerning the taxation of loyalty programs. The Seventh Circuit remanded the case to the Tax Court for further review.

PFAS in cosmetics is quickly becoming one of the highest-stakes compliance issues in the beauty and personal care industry.

The president of the Competition Appeal Tribunal (CAT) has signalled a more rigorous approach to scrutinising opt-out collective actions at the certification stage, with particular attention to whether the financial benefits of such claims flow to the claimant class or primarily to their lawyers and funders. Coming at a time when the UK Law Commission is consulting on expanding the scope of the opt-out regime, this development warrants careful consideration by all those with interests in the UK litigation funding market.

A recent Illinois appellate decision has narrowed a key protection that state and local government contractors have long been able to rely on under Illinois’ Biometric Information Privacy Act (BIPA). In Thomas v. Cornerstone Services, Inc., the Illinois Appellate Court held that BIPA’s government contractor exemption does not provide blanket immunity to contractors simply because they hold a contract or subcontract with a state agency or local unit of government. The ruling carries important compliance implications for contractors and subcontractors operating across both government and private-sector markets.

On April 6, 2026, the U.S. Environmental Protection Agency (EPA) published the draft Sixth Contaminant Candidate List (CCL 6), marking a significant step in the agency's effort to identify and evaluate unregulated contaminants in public water systems. The CCL 6 includes 75 chemicals, four chemical groups (disinfection byproducts (DBP), microplastics, per- and polyfluoroalkyl substances (PFAS), and pharmaceuticals), and nine microbes.

An Alabama mother filed suit on April 8, 2026, in the U.S. District Court for the Northern District of California against Roblox and Fortnite developer Epic Games, alleging that they design their platforms and games to be addictive through random reward tactics, especially targeting minors. The case is Turner et al. v. Epic Games Inc. et al., Case No. 3:26-cv-02975.

In its April 21, 2026, opinion, the U.S. Court of Appeals for the Tenth Circuit affirmed the lower court’s ruling in Liberty Global, holding that the codified economic substance doctrine applies even when a taxpayer mechanically utilizes the provisions of the Tax Code. The court also held that common mergers and acquisitions elements and basic business transactions are not categorically carved out from the economic substance doctrine. The court dismissed the taxpayer’s argument that a separate relevancy determination needs to be made before the economic substance doctrine can be applied.

The landscape of counterfeiting litigation is shifting in ways that place online marketplace operators at the center of disputes from two directions. Brand owners are escalating efforts to hold platforms liable for counterfeit goods sold through their sites, while some marketplace operators have begun joining brand owners as co-plaintiffs to pursue counterfeiters directly. This dual role has significant implications for how platforms manage their legal exposure and their relationships with brand owners.

Meta continues to face lawsuits around the country alleging that its platforms are designed to induce compulsive use by children. In March 2026, a California jury delivered a landmark verdict that Meta and YouTube were liable for allegedly addictive platform features that resulted in a child’s mental health distress.  

The Modernization of Cosmetics Regulation Act of 2022 (MoCRA) marked the most significant expansion of FDA’s authority over cosmetics in 80 years — and the agency is putting that authority to work. From the launch of a new adverse event reporting tool to forthcoming rules on fragrance allergens and good manufacturing practices (GMP), FDA is reshaping the regulatory landscape for manufacturers, packers, and distributors of cosmetic and personal care products.
