Brian Del Gatto (Partner-Phoenix), Colt Dodrill (Of Counsel-Phoenix) and Jenna Vance (Associate-Phoenix) obtained summary judgment in Maricopa County Superior Court for Wilson Elser’s clients, a peer-to-peer car sharing program and a shared vehicle’s owner. The plaintiff sought damages from our clients under the theory of negligent entrustment. Colt and Jenna established that of the co-defendants mother and daughter, only the mother was authorized to operate the shared vehicle, whereas her daughter who was operating it at the time of the accident, was not authorized to do so. The plaintiff argued that the mother’s prior return of a shared vehicle with a “weed smell” imposed on our clients a duty to remove her from client’s program and the breach of that duty caused the accident. Colt and Jenna successfully argued no causal link existed between the mother’s purported marijuana use and the daughter’s accident. Finding no duty of care owed to the plaintiff, the court entered summary judgment in favor of the peer-to-peer car-sharing program. Finding no proximate cause, the court entered summary judgment in favor of the shared vehicle’s owner.
