Why It Matters
A recent Congressional Research Service (CRS) report identifies legal conflicts that could reshape federal policy across multiple domains. Published in July, the CRS analysis tracks new and widening circuit splits from June 2026 decisions spanning six distinct legal areas, signaling potential flashpoints for legislative action or Supreme Court intervention.
When federal appeals courts reach conflicting conclusions on the same legal question, the nation's laws operate differently depending on geography. Federal law is applied inconsistently depending on where a case is heard.
The Big Picture
Circuit splits create legal uncertainty that Congress is designed to address. The CRS report alerts lawmakers to unresolved disagreements that may require legislative action or that may be candidates for Supreme Court review. Three of the splits carry immediate policy weight.
The Energy Policy and Conservation Act (ECPA) preemption question divides the Second and Ninth Circuits on whether states and cities can ban fossil-fuel appliances in new buildings. The Second Circuit held that the law does not preempt such measures, reasoning that EPCA preempts standardized energy efficiency rules, not rules about how consumers use appliances. The Ninth Circuit reached the opposite conclusion, finding EPCA's preemption provision covers restrictions on consumer use of appliances as well. This split directly affects whether state and local governments can enact fossil fuel bans in buildings.
In the EPCA cases, the Second Circuit focused on an appliance's standardized energy use under test conditions before reaching the consumer, while the Ninth Circuit interpreted the statute's reference to a product's point of use to include consumer-facing restrictions.
The Federal Debt Collection Procedures Act (FDCPA) split concerns whether courts can overlook violations of mandatory venue transfer rules. The Second Circuit held that when a debtor timely requests a venue transfer, transfer is mandatory and denial is not subject to harmless error review. The Sixth Circuit disagrees on whether such violations warrant harmless error review.
The FDCPA venue transfer split hinges on whether mandatory statutory language truly forbids harmless error analysis. The Ninth Circuit has reached similar conclusions as the Second Circuit about the mandatory language and the inapplicability of harmless error review, but the Sixth Circuit has not.
The Seventh Circuit split with the D.C. Circuit on the nonconstitutional claims issue regarding the Adam Walsh Act but joined the Third, Fourth, Sixth, Eighth, Ninth, and Eleventh Circuits on the nonconstitutional claims issue. The Seventh Circuit largely agreed with the Fourth and Sixth Circuits that such claims are only reviewable in the context of a removal order.
The Adam Walsh Act disputes turn on how broadly courts read statutory bars to judicial review. These splits affect immigration proceedings where aliens petition for immediate relative status to adjust to lawful permanent resident status, a process governed by the Immigration and Nationality Act.
The Bottom Line
The longer these disagreements persist across circuits, the greater the incentive for one side to seek Supreme Court review, potentially forcing a nationwide resolution Congress could have shaped itself.
