What are the key differences between federal and state court systems in terms of jurisdiction and authority?

The key differences between federal and state court systems lie in their jurisdiction and authority. Federal courts have jurisdiction over cases involving Federal Laws, the Constitution, and disputes between states. State courts have jurisdiction over cases involving state laws, local ordinances, and most civil and criminal matters within their state. Federal courts have authority to interpret federal laws and the Constitution, while state courts have authority to interpret state laws and their own state constitution.
