The New Jersey Supreme Court ruled on June 22, 2023, that the smell of marijuana in a vehicle does not automatically allow police to search the trunk or engine compartment without additional evidence. This decision affects how law enforcement can conduct searches based on the odor of marijuana and has implications for future traffic stops and searches across the state.

The case, State v. Cornelius C. Cohen (A-50-21), arose from a traffic stop on January 17, 2016, when State Trooper Charles Travis pulled over Cohen's vehicle after receiving a tip from a confidential informant. The informant claimed that Cohen was involved in transporting firearms from the Carolinas to New Jersey. During the stop, Trooper Travis detected a strong odor of raw marijuana and observed marijuana residue on Cohen's clothing. Despite not finding any marijuana in the vehicle's passenger compartment, the trooper searched the engine compartment and trunk without a warrant, discovering a rifle, a revolver, and ammunition.

Cohen moved to suppress the evidence seized during the search, arguing that the trooper's actions exceeded the legal boundaries set by the automobile exception to the warrant requirement. The trial court denied his motion, stating that the odor of marijuana justified the search. The Appellate Division upheld this decision, leading Cohen to appeal to the New Jersey Supreme Court.

The Supreme Court's unanimous opinion, written by Justice Pierre-Louis, reversed the lower court's ruling. The court found that while the smell of marijuana can establish probable cause for a search, it does not automatically extend to areas beyond the passenger compartment of the vehicle. The court emphasized that the initial search of Cohen and the passenger compartment was valid, but the subsequent searches of the engine compartment and trunk were not justified. Justice Pierre-Louis stated, "the trooper's initial search yielded no results and provided no justification to extend the zone of the... search further than the persons of the occupants or the interior of the car."

The ruling clarified that a general smell of marijuana does not give police carte blanche to search all areas of a vehicle. Instead, there must be specific indicators that suggest contraband is present in those areas. The court referenced previous cases, noting that searches extending beyond the passenger compartment typically involved additional evidence or circumstances that warranted such actions.

This decision is significant as it sets a precedent for how law enforcement in New Jersey can conduct searches based on the smell of marijuana. It limits the scope of searches, requiring police to have more than just the odor of marijuana to justify searching a vehicle's trunk or engine compartment. This ruling could impact future cases involving traffic stops and searches, as it reinforces the need for probable cause and reasonable scope in law enforcement actions.

Moving forward, the ruling may lead to fewer searches based solely on the smell of marijuana, particularly as New Jersey continues to navigate the legalization of cannabis. It signals a shift towards protecting individuals' rights against unreasonable searches and emphasizes the importance of adhering to constitutional standards.

The court's decision also raises questions about whether this ruling can be appealed or if there are related cases pending. As of now, there is no indication that the decision will be appealed to a higher court, and it stands as the current legal standard in New Jersey regarding searches based on the odor of marijuana.
