The Iowa Supreme Court has released an opinion in Thompson v. Kaczinski, 2009 WL 3786632 (Iowa 2009) and adopted the Restatement (Third) of Torts approach to both duty and causation. The case arose after "a motorist lost control of his car on a rural gravel road and crashed upon encountering a trampoline that had been displaced by the wind from an adjoining yard to the surface of the road. He and his spouse sued the owners of the trampoline." The lower court dismissed the case, holding that the defendants did not owe a duty to the plaintiffs and that causation did not exist as a matter of law.
“An actor ordinarily has a duty to exercise reasonable care when the actor’s conduct creates a risk of physical harm.” Restatement (Third) of Torts: Liab. for Physical Harm § 7(a), at 90 (Proposed Final Draft No. 1, 2005). As the Court explained, "
[I]n most cases involving physical harm, courts “need not concern themselves with the existence or content of this ordinary duty,” but instead may proceed directly to the elements of liability set forth in section 6. Id. § 6 cmt. f, at 81. The general duty of reasonable care will apply in most cases, and thus courts “can rely directly on § 6 and need not refer to duty on a case-by-case basis.” Id. § 7 cmt. a, at 90.
