Summary
The Supreme Court of Hawaiʻi held that probable cause to arrest requires more than mere suspicion but less than certainty, rejecting the Intermediate Court of Appeals' characterization of the standard as less demanding than proof by a preponderance of the evidence. Applying the correct standard, the court held that police had probable cause to arrest Shanelle Maganis for unauthorized control of a propelled vehicle as either a principal or an accomplice, making her post-arrest confession admissible.

Questions Presented
- Whether the ICA misstated Hawaiʻi's probable-cause standard by characterizing probable cause as less demanding than proof by a preponderance of the evidence.
- Whether the facts known to the arresting officer established probable cause to arrest Maganis for unauthorized control of a propelled vehicle as a principal or accomplice.
- Whether Maganis's post-arrest confession was admissible when the arrest was supported by probable cause.
Holdings
- Probable cause to arrest requires more than a mere suspicion but less than a certainty; the ICA's formulation that probable cause is less demanding than proof by a preponderance of the evidence improperly watered down the governing standard.
- The officer had probable cause to arrest Maganis for unauthorized control of a propelled vehicle either as a principal or as an accomplice.
- Because the arrest was supported by probable cause, Maganis's post-arrest confession was admissible and the circuit court erred in dismissing the charge on that basis.
Key quotations
“Probable cause exists when the facts and circumstances within one's knowledge and of which one has reasonably trustworthy information are sufficient in themselves to warrant a person of reasonable caution to believe that an offense has been committed. This requires more than a mere suspicion but less than a certainty.” (682)
“The rule of probable cause is a practical, nontechnical conception affording the best compromise that has been found for accommodating these often opposing interests.” (683)
“common enterprise is not a substitute for the mandate in our jurisdiction that probable cause based on specific "facts leading sensibly to their conclusions of probability," must be established in each case.” (684)
Factual background
Police observed Maganis in the passenger seat of a black Acura parked at a residence and later learned that the vehicle had been reported stolen. Officers found that the vehicle's ignition had been damaged, that its front and rear license plates did not match, and that the plate issued to the vehicle was on the floorboard of the front passenger seat where Maganis had been sitting. A resident identified Maganis as someone he knew and stated that Cambra, whom he did not know, had backed the Acura into his driveway. Maganis was arrested and later confessed that she and Cambra had taken turns driving the Acura while knowing it was stolen.
Procedural history
The Circuit Court of the First Circuit dismissed Count II of the amended complaint, concluding that the arrest lacked probable cause and that Maganis's confession was fruit of the poisonous tree. The ICA reversed, holding that probable cause existed. The Supreme Court held that the ICA misstated the probable-cause standard but reached the correct result on the record; it vacated the offending portion of the ICA opinion, affirmed the remainder, and remanded to the circuit court.
Remand instructions
Remanded to the circuit court for proceedings consistent with the opinion. Section III.A. of the ICA's opinion was vacated to the extent it mischaracterized the probable-cause standard, and the ICA's opinion was affirmed in all other respects.
