"A lack of territorial jurisdiction means that the specific court where a lawsuit has been filed does not have the legal authority to hear the case because the dispute lacks a sufficient connection to that court's geographic boundaries, such as where the defendant lives, where a contract was signed, or where the injury occurred; this single issue can lead to the complete dismissal of an otherwise valid case because courts are powerless to adjudicate matters over which they have no authority, ensuring that defendants are not subjected to litigation in unfairly distant or inconvenient forums, and thus, even if the plaintiff's claims are legally sound, the case must be thrown out unless it can be refiled in a court that possesses the proper territorial power."
