"Probable cause" has long been one of those terms that made the jump from legal jargon to household term, especially with regards to drivers who get pulled over. The struggle over what that allows on American roads — and what it doesn't — took a new turn last week with a Florida ruling that threw out a conviction stemming from a police officer who found something wrong with the color of a car.

In 2010, a deputy in Florida's Escambia County saw one Kendrick Van Teamer drive by in a bright green Chevrolet. The deputy ran his plates, and found the registration matched a blue Chevrolet. There were no warrants out for Teamer, no reports of stolen vehicles and no pending crimes that involved either a blue or green Chevy. Teamer also wasn't violating any traffic laws.

But the deputy pulled Teamer over anyway, simply because of the mismatch of the car's color. Teamer said the car had been recently painted, which was true. It also contained small amounts of cocaine, marijuana and $1,100 in cash. Teamer was charged with drug trafficking and possession, convicted and sentenced to six years in prison.

Teamer appealed, and last week as noted by The Newspaper, the Florida Supreme Court ordered him freed on a 5-2 decision, upholding a lower appeals court ruling that the deputy was wrong to stop Teamer simply becuase the color of his car didn't match its registration. The court noted that in numerous U.S. Supreme Court rulings, justices have found police can't pull someone over for everday behavior that's not linked to a crime, saying Teamer's stop was not different from those triggered by the race of the driver:

The color discrepancy here is not “inherently suspicious” or “unusual” enough or so “out of the ordinary” as to provide an officer with a reasonable suspicion of criminal activity, especially given the fact that it is not against the law in Florida to change the color of your vehicle without notifying the DHSMV.

The dissenting judges noted that courts across the country faced with this same challenge have come down on both sides, and contended that a question about a car's color was far more than a simple hunch: "A stop in such circumstances cannot fairly be called an 'arbitrary and abusive' police practice."

The fine details about what constitutes probable cause in traffic stops has come up numerous times before; it's a guiding principle in DUI roadblocks, where police must either randomly stop vehicles or pause every one. Don't be surprised if the Supreme Court itself has to weigh in someday soon on whether motorists can be considered suspicious simply for the color of their rides.
