This marked the first time that the New Hampshire Supreme Court had been asked to rule whether a driver may validly consent to a warrantless search of the personal effects of a passenger. In this case, there was no claim that the driver had actual authority or joint ownership of the defendant's bag. Rather, the question was whether in the minds of the officers the driver had "apparent authority" to consent to a search of the bag.
The doctrine of "apparent authority" validates a search if the police reasonably but mistakenly believe the party consenting has the authority to do so. The U.S. Supreme Court has not yet applied the doctrine of apparent authority to automobile searches, but lower federal courts and some state courts have already done so. Courts that have already decided the issue have engaged in fact-specific inquiries. Generally, under the doctrine, the search is legal if, under the totality of the circumstances surrounding it, it is objectively reasonable for the officers to believe the suspect had consented.
Applying this doctrine to the facts of the case at issue, the New Hampshire court found that it was reasonable for the officer to search the passenger's zipper bag.
The officer made it clear, up front, that he was looking for drugs, so it was logical for him to believe he had consent to search containers inside the car that might contain drugs. In addition, the bag could have reasonably belonged to the driver and was a type that often is used to hold cassette tapes and CDs. It was found on the seat behind the driver, and there was nothing to alert the officer that the bag belonged to anyone other than the driver.
Further, there was no tag on it; it was a common type of container, and nobody denied ownership or claimed ownership of it. And finally, neither the driver nor the passenger objected to the search or attempted to withdraw their consent when the officer picked up the bag and sniffed it. So the circumstances were not ambiguous enough to require the officer to inquire further before opening the bag.
