Answer: Persuasive authority
Explanation:
Persuasive authority is a decision that a court may follow but does not have to. The decision may be from courts with lower, equal, or higher standing with the court it is brought to but from another jurisdiction.
The case in question here will be dealt with according to Iowa state law so bringing a decision by the Nebraska Supreme Court is from another jurisdiction. The Iowa judge can either choose to follow the precedent set by Nebraska or not at their own discretion.
