Jurisdiction is the constitutionally or statutorily defined authority of a court to hear and determine a case. Whether a court can exercise this power depends on several key factors:12

  • Legal Framework: Jurisdiction is typically defined by statute or constitutional provisions that establish the sphere of a court's influence.32
  • Subject Matter: Courts are often specialized by the type of case, such as probate courts for estates or juvenile courts for minors.4
  • Geography and Territory: A court’s authority is often limited to a specific territory. In federal systems, rules determine whether a case belongs in state or federal court.12
  • Due Process: In the United States, constitutional protections like the due process clause limit a court's reach to prevent unreasonable burdens on defendants.2
  • Connection and Convenience: Courts may decline to hear cases—even if they have technical jurisdiction—if they lack a meaningful connection to the parties or the controversy, or if the forum is deemed forum non conveniens (an inconvenient place for trial).2
  • Consent: Parties may sometimes agree to a court's jurisdiction through contracts or by appearing in court to litigate without objection.2
