Our court system has a hierarchy at both the federal and state levels. Lower courts hear less serious criminal cases and smaller civil claims, while appeals and more serious matters move up through higher courts. Original jurisdiction refers to the first hearing of a case, while appellate jurisdiction allows for appeals of decisions. The High Court of Australia hears constitutional matters and appeals from lower federal and state courts. Specialist courts like the Family Court and Federal Court handle specific areas of law, while state courts include the Court of Appeal, Supreme Court, District Court, and Magistrates Court which each have increasing or decreasing jurisdiction based on the seriousness or monetary value of a case.
