On May 18, 2026, the U.S. Supreme Court quietly closed one chapter in the long‑running fight over who gets to ship alcoholic beverages directly to consumers. In a one‑line order denying review, the Court declined to hear Day v. Henry (No. 25-788).. For people in the alcohol business, that short order carries real weight, so it’s worth unpacking what it does and, just as importantly, what it doesn’t do.
What a “denial of certiorari” actually means
The Supreme Court hears only a tiny fraction of the cases it is asked to review. When the Court declines — a “denial of certiorari” — it is not saying the lower court got it right. It is simply choosing not to weigh in. The practical effect is that the lower court’s decision stands. Here, that means the Ninth Circuit’s 2025 ruling in Day v. Henry, 152 F.4th 961, is now the controlling law across the Ninth Circuit — which includes California.
A quick recap of Day
Day was about Arizona law. Arizona lets out-of-state wine retailers ship directly to Arizona consumers, but only if the retailers have a physical store in the state. A group of out‑of‑state retailers argued that rule was unconstitutional discrimination: in‑state shops could ship, but they could not.
The Ninth Circuit disagreed and upheld Arizona’s rule. The court ruled that the in-state physical presence requirement is an “essential feature” of Arizona’s three-tier system, which regulates the production, wholesale, and retail of all spirituous liquors and alcoholic beverages. The court’s reasoning, in plain terms: even if the requirement treats out‑of‑state wine retailers differently, the physical‑presence rule is an essential part of Arizona’s three‑tier system — the legal framework banning vertical integration between the state’s producer, wholesale, and retail alcohol businesses. The court worried that allowing out‑of‑state retailers without a footprint in Arizona to ship to the state would let them skip the wholesale tier entirely and slip out of Arizona’s regulatory reach. In the court’s words, that would cut so many holes in the system that it “would functionally cease to exist.”
Important: Day is about Arizona, not California
It is tempting to read Day as the last word on out-of-state retailers’ direct‑to‑consumer shipping everywhere in the Ninth Circuit. It is not. Day interpreted Arizona’s specific statutes. The Supreme Court has repeatedly said that each state’s alcohol laws must be judged on their own features. California’s laws are different from Arizona’s — and the differences matter.
How California’s law is different
For out‑of‑state retailers hoping to ship wine to California, the key provision is California Business and Professions Code section 23661.2. Unlike Arizona, California law does not require out-of-state retailers to have a physical presence in the state. Instead, California imposes a reciprocity requirement: wine can be shipped to the state only if the shipper’s home state grants California retailers and residents an “equal reciprocal shipping privilege.” In plain English: you can send your award-winning Cabernet to California only if your state lets California retailers ship into yours. Even then, out-of-state retailers are limited to shipping 2 cases of wine per month (up to 18 liters) to each California consumer.
(A neighboring provision, section 23661.3, is sometimes confused with this one. That section is California’s winegrower direct‑shipper permit. It lets wineries licensed in any state ship to California consumers on equal terms, and it does not turn on reciprocity. It governs producers, not retailers, and is a different animal.)
What Granholm said about reciprocity
This is where an older Supreme Court case becomes central. In Granholm v. Heald (2005), the Court struck down state laws that let in‑state wineries ship directly to consumers while blocking out‑of‑state wineries. Along the way, it took a hard look at the national patchwork of shipping laws — including reciprocity requirements — and it was blunt. Conditioning one state’s market access on a “reciprocal right in the shipping State,” the Court said, is exactly the kind of arrangement the Commerce Clause was written to prevent. It described the patchwork of bans and reciprocity rules as “essentially the product of an ongoing, low‑level trade war,” warning that such laws breed the “trade rivalries and animosities” the Constitution sought to avoid. The Court even singled out California’s own reciprocity law as an obvious piece of economic protectionism.
Why section 23661.2 still looks shaky — even after Day
Here is the key takeaway for the industry: Day does not rescue reciprocity-based limitations on out-of-state retailers’ direct shipping to California consumers. Under Granholm, California’s section 23661.2 is still likely unconstitutional.
The reciprocity requirement does nothing to support California’s three-tier system. It gives no additional oversight and doesn’t ensure alcohol flows through licensed wholesalers. Nor does it advance advance any public health or safety objective. It simply gates access to leverage California retailers’ access to other markets.
The bottom line
For the vast majority of wine retailers outside of Arizona, the Supreme Court’s denial of certiorari in Day dashed the hope that they might reach millions of new consumers in the state. However, it did not close the door to a challenge in California. California’s reciprocity‑based approach to retailer direct shipping sits in real tension with Granholm. Any company whose business model depends on shipping wine across state lines should watch this space closely — and should not be surprised to see the reciprocity requirement tested sooner rather than later.
