In brief
Overview
Police stopped the car and found drugs packaged for distribution in the rear‑seat armrest and a large amount of cash in the glove compartment.
According to Justice O'Connor, the central legal question is whether the officers had probable cause to arrest all three occupants based on those findings.
Background and question before the Court
According to Justice O'Connor, justice O’Connor asked whether the rear‑seat armrest was pushed up.
According to Justice O'Connor, justice O’Connor asked if there was probable cause for the arrest of all three occupants at the time they were found.
What each side argues
Maryland (Petitioner)
The totality of the circumstances, including the packaged narcotics, established probable cause to arrest all occupants.
According to Mr. Srinivasan, when drugs packaged for distribution are readily discoverable by passengers, a reasonable officer may infer that each passenger is likely aware of the drugs.
According to Ms. Forster, the driver can be imputed knowledge of the contents of the car and therefore may be arrested.
Pringle (Respondent)
According to Ms. Forster, possession requires not just knowledge, but also the intent to exercise dominion and control over the drug.
According to Ms. Forster, because the drugs were concealed and not visible to the occupants, the situation is analogous to Di Re, where mere presence does not create probable cause.
According to Mr. Srinivasan, innocent persons may be arrested, and the probable cause standard accepts that possibility as a cost of effective law enforcement.
What happened at oral argument
According to Justice O'Connor, justice O’Connor asked whether the rear‑seat armrest was pushed up.
According to Justice O'Connor, justice O’Connor asked if there was probable cause for the arrest of all three occupants.
According to Justice O'Connor, justice O’Connor referenced a brief suggesting a broad rule that probable cause exists to arrest all occupants when commercial quantities of narcotics are found.
According to Justice O'Connor, justice O’Connor asked whether different factors, such as the presence of a young child, would affect the analysis.
According to Justice, the driver’s knowledge was questioned, noting it might be harder for the driver to place the bags in the backseat than for passengers.
