Plaintiff suffered injuries while a forty-year-old man struck a piñata at a birthday party. The judge charged both Model Jury Charges (Civil), 5.20F(4), "Social Guest – Defined and General Duty Owed" (rev. Dec. 2014) (the Model Charge), and Exception (2) to the Model Charge. That exception states that "[i]n cases where the host is conducting some 'activity' on the premises at the time of [the] guest’s presence, [the host] is under an obligation to exercise reasonable care for the protection of [the] guest." This court held that when a plaintiff sustains an injury resulting solely from an "activity" on the host's property – as opposed to an injury caused by a combination of that activity and a physical dangerous condition on the property – then the judge should only charge Exception (2).
