N.D. Cent. Code § 60-01-24: Presumption of willfulness or gross negligence

If a thing is lost or injured during its deposit and the depositary refuses to inform the depositor of the circumstances under which the loss or injury occurred so far as the depositary has information concerning them, or if the depositary willfully misrepresents the circumstances to the depositor, the depositary is presumed to have permitted the loss or injury to occur willfully or by gross negligence.
