Trial Verdicts

Ms. Harrigan obtained a defense verdict following a five-day jury trial in Maricopa County, Arizona, involving a chain reaction rear-end motor vehicle collision. The plaintiff demanded over $200,000 in damages, alleging our client negligently operated her vehicle by stopping abruptly, which caused the accident and her injuries. On cross-examination at trial, the plaintiff admitted that our client’s action of stopping her vehicle for traffic observed ahead would have been reasonable under the circumstances and would not have constituted negligence. Ms. Harrigan also obtained partial summary judgment as a matter of law on the plaintiff’s claims for permanent disfigurement, permanent disability, wage loss, loss of earning capacity, and past medical expenses, further reducing the amount the plaintiff could request from the jury. The jury deliberated for less than two hours and unanimously rendered a complete defense verdict.
