Even if Javier was suing for $100,000.00, he could only file in state court, as according to the diversity jurisdiction, there must be complete diversity to file suit in federal court. Since Javier and Energy-Auto are both ‘citizens’ of New York, there is no complete diversity of jurisdiction between the plaintiff and defendant. As to whether it is more advantageous to file in a state or federal court, it comes down to the details of the suit. The plaintiff should take into consideration the governing rules of each court, their potential jury pools, and even how quickly the case might move through the courts. I believe that the case would have to be evaluated on its own facts and merits.
