Background
When California voters legalized recreational marijuana, the Legislature kept some restrictions on how it can be carried in vehicles. One of those restrictions, in Health and Safety Code section 11362.3, makes it an infraction — the lowest level of offense, similar to a parking ticket — to have an “open container” of marijuana in a vehicle. The case before the court asked whether scattered marijuana crumbs on the floor of a car count as an open container, and whether finding such crumbs gives police probable cause to conduct a warrantless search.
Three Sacramento officers pulled over a car for failing to fully stop behind a crosswalk limit line before turning. The driver and her front-seat passenger, Davonyae Sellers, were cooperative; a records check came back clean; and there was no indication the driver was impaired. The officers shined flashlights into the car, asked about marijuana and guns, and noticed a rolling tray on the back seat plus what they called “weed crumbs” scattered on the rear floorboard. The driver explained the residue came from the tray. The officers ordered everyone out, searched the car and the driver’s purse, and found 0.36 grams of unidentified plant material on the floor (which was never tested) and an unregistered pistol near the front passenger seat.
Sellers was charged with unlawful firearm possession and moved to suppress the gun, arguing the search was illegal. The trial court denied the motion, the Court of Appeal affirmed, and both lower courts reasoned that even though marijuana itself is legal, the loose residue qualified as contraband under the open-container rule, which alone supplied probable cause. One Court of Appeal justice dissented, calling the stop a pretext and emphasizing that an “open container” violation requires an actual container. The Supreme Court granted review.
The Court’s Holding
The California Supreme Court reversed in a unanimous opinion by Justice Liu. The court held that loose marijuana scattered on the floor of a car is not an “open container” within the meaning of section 11362.3. The plain meaning of “open container” requires a container — a packet, bag, jar, or similar receptacle — that has been opened or whose seal is broken. Stray crumbs on the floor, separated from any wrapping, simply do not fit that definition. The Attorney General had conceded as much in the lower courts, and the court agreed that reading the statute to forbid any uncontained marijuana in a car would rewrite the Legislature’s chosen language.
Because the small amount of residue was not itself unlawful — possession of small quantities of marijuana by adults is legal in California, and there was no evidence the material on the floor was being used or readily accessible for use — observing it did not give the officers probable cause to believe the car contained evidence of a crime. The court also rejected the alternative ground the Court of Appeal had relied on: that the totality of the circumstances (a rolling tray, a denial of marijuana in the car, an officer’s perception of nervousness) supplied probable cause. None of those facts, alone or combined, suggested ongoing criminal activity. The court emphasized that legal items and innocent behavior do not become suspicious just because they are present together during a routine traffic stop.
Because the search was unlawful, the gun should have been suppressed. The court issued a peremptory writ directing the trial court to grant the suppression motion.
Key Takeaways
- An “open container” of marijuana under California law requires an actual container that has been opened. Loose residue on a car floor does not qualify, and merely seeing it does not justify a search.
- Because adult possession of small amounts of marijuana is legal in California, the smell or sight of marijuana — without more — generally cannot supply probable cause for a warrantless vehicle search.
- Police cannot stack legal observations (a rolling tray, residue, denial of having marijuana, perceived nervousness during a traffic stop) into probable cause when none of the underlying facts indicate a crime.
- Defense attorneys handling traffic-stop suppression motions should look closely at whether the officer’s stated basis for searching survives the legalization of recreational marijuana.
- Police agencies need updated training on how the post-legalization landscape limits the use of marijuana indicators as a basis for vehicle searches.
Why It Matters
This decision has immediate, practical consequences for traffic stops across California. For years after legalization, officers continued to use the visible presence of marijuana — including small amounts of residue or paraphernalia — as the gateway to wider warrantless searches. The court has now made clear that the open-container infraction is a narrow rule about actual containers, not a license to treat any marijuana indicator as criminal evidence. Searches that rely on that theory will face serious challenges, and convictions built on the resulting evidence may be vulnerable on appeal.
For the broader public, the ruling reinforces a simple principle: legal conduct does not become unlawful because it makes a police officer curious. Drivers and passengers who comply with the open-container rules — keeping marijuana in a sealed or closed receptacle when traveling — should not face vehicle searches based on stray crumbs, rolling trays, or other artifacts of legal use.
