Forum non conveniens example
Al sues Bob after a car accident which injures both parties. The accident took place in New Jersey, and the bulk of the evidence, including police reports, wreckage and witnesses, is located there. Both of the cars involved in the accident were registered an insured in New Jersey. In addition, Al is a citizen of New Jersey. However, Bob is a citizen of California. Al sues Bob in California. Even though the the California court has jurisdiction, it can dismiss the suit based on forum non conveniens, because having the trial in California will be nearly impossible, and a suit in New Jersey would be both convenient and jurisdictionally proper (as the location where the accident took place).
