The California Supreme Court ruled that police cannot search a vehicle simply because they find loose, scattered marijuana crumbs on the floor. The court said marijuana must be in a usable, imminently consumable condition to constitute an open container violation and give officers probable cause to search the car.

Why it matters

This ruling provides more protections for drivers who legally possess small amounts of marijuana, limiting when police can search vehicles based solely on the presence of the drug. It could impact how law enforcement handles routine traffic stops involving marijuana in the state.

The details

In a unanimous decision, the court reversed lower court rulings that had allowed police to search a vehicle after finding 0.36 grams of loose marijuana crumbs on the floor. The judges said that for marijuana to constitute an open container, it must be in a usable quantity and readily accessible for immediate consumption, like a can of beer. Scattered crumbs on the floor do not meet that standard.

What they’re saying

“We hold that at a minimum, to constitute a violation of (the open container law), marijuana in a vehicle must be of a usable quantity, in imminently usable condition, and readily accessible to an occupant.”

— Goodwin Liu, Associate Justice, California Supreme Court

What’s next

The ruling could lead to changes in how police handle traffic stops involving small amounts of marijuana in California, as officers will now need to find the drug in a more readily consumable state to justify vehicle searches.

The takeaway

This decision provides more legal protections for drivers who possess small amounts of marijuana, limiting when police can search vehicles based solely on the presence of the drug. It reflects the evolving legal landscape around cannabis in California since the state legalized recreational use in 2016.
