The Robinsons' Oklahoma attorney brought the lawsuit in state court in Creek County, Oklahoma, the county in which the accident had occurred. Creek County was at that time known as home to some of the most plaintiff sympathetic juries in the country. However, since the lawsuit met requirements for concurrent jurisdiction in both state and federal court, Audi and Volkswagen would have had the ability to ask for the case to be removed from state court in Creek County and taken directly to federal court. One of the factors which governs concurrent jurisdiction is diversity of citizenship, or whether a defendant and plaintiff are from the same state. In the case of multiple defendants, if one defendants' state citizenship matches the plaintiff's, concurrent federal jurisdiction does not apply and the case cannot be removed to federal court unless the case concerns a matter of federal law. It has therefore been stated that the reason the Robinsons' attorney added the New York regional distributor and New York dealership as defendants was to prevent Audi and Volkswagen from being able to remove the case from what was generally seen as a Creek County pro-plaintiffs' jury to what would be a federal court jury in Tulsa that might be more sympathetic to the car manufacturers' case. The Robinsons had not yet completed a move to Arizona, so they were still considered to be legal residents of New York.
