$1.$ Ms$.$ Simpson could potentially file this lawsuit in several courts, including:$-$ The Superior Court of Pierce County, Washington, as the incident occurred within the jurisdiction where the injury took place.$-$ A federal district court in Washington if diversity jurisdiction applies due to Ms$.$ Simpson being a resident of California, Quikktripp being incorporated in Arizona, and the amount in controversy exceeding $$75,000.-$ Potentially, she could also file in a federal district court in Nevada or Arizona due to Quikktripp's headquarters and incorporation locations respectively, though this would depend on the specific circumstances and legal strategy$\mathrm{.}2.$ The chosen court$($s$)$ would have jurisdiction over this lawsuit as follows:$-$ The Superior Court of Pierce County, Washington, would have jurisdiction based on personal jurisdiction since the injury occurred within its geographic boundaries.$-$ A federal district court in Washington would have jurisdiction under diversity jurisdiction as Ms$.$ Simpson, a California resident, is suing Quikktripp, an Arizona corporation, and the amount in controversy exceeds $$75,000.$ This is provided that Quikktripp has sufficient minimum contacts with the state of Washington to establish personal jurisdiction.$-$ If filing in a federal district court in Nevada or Arizona, jurisdiction would similarly be based on diversity jurisdiction, considering Quikktripp's headquarters in Nevada and incorporation in Arizona.
