Courts are the backbone of our legal system, but not all courts are created equal. Federal and state courts have different powers and handle different types of cases. Understanding these distinctions is crucial for navigating the legal landscape.

Jurisdiction is the key to unlocking a court's power. Subject matter jurisdiction determines what types of cases a court can hear, while personal jurisdiction governs its authority over the parties involved. Venue rules ensure cases are heard in the most appropriate location.

Federal vs State Court Jurisdiction

Jurisdictional Differences

• Federal courts possess limited jurisdiction derived from Article III of the U.S. Constitution
• State courts maintain general jurisdiction over a wide range of cases
• Federal courts primarily hear cases involving federal laws, constitutional issues, and disputes between citizens of different states
• State courts handle most criminal cases and civil disputes within their state
• Supremacy Clause establishes federal law precedence over state law when conflicts arise, affecting case adjudication in both court systems

Concurrent and Supplemental Jurisdiction

• State courts can hear federal claims under concurrent jurisdiction
• Federal courts cannot hear state law claims unless they have supplemental jurisdiction or diversity jurisdiction
• Supplemental jurisdiction allows federal courts to hear state law claims closely related to a federal claim already properly before the court
• Removal process enables defendants to transfer certain cases from state to federal court if they meet specific criteria (diversity of citizenship or federal question jurisdiction)

Jurisdiction: Subject Matter, Personal, and Venue

Subject Matter Jurisdiction

• Refers to a court's authority to hear specific types of cases based on the nature of the controversy or parties involved
• Cannot be waived and can be raised at any time during litigation
• Examples include federal question jurisdiction for cases involving federal law and diversity jurisdiction for disputes between citizens of different states

Personal Jurisdiction

• Court's power over the parties in a lawsuit
• Typically established through minimum contacts with the forum state or consent
• Can be waived if not timely asserted
• Concepts of general and specific personal jurisdiction determine court authority over out-of-state defendants based on their connections to the forum state
• Examples: A company regularly conducting business in a state (general jurisdiction) or a car accident involving an out-of-state driver (specific jurisdiction)

Venue

• Determines the specific geographic location where a case should be heard within a court system that has both subject matter and personal jurisdiction
• Can be waived if not timely asserted
• Examples: Federal venue statutes specifying proper districts for filing lawsuits or state laws designating appropriate counties for case hearings

Factors for Court Jurisdiction

Amount in Controversy and Long-arm Statutes

• Amount in controversy requirement sets a monetary threshold for cases to be heard in federal court under diversity jurisdiction (currently exceeds $75,000)
• Long-arm statutes extend a state's personal jurisdiction over non-resident defendants who have sufficient minimum contacts with the state
• "Purposeful availment" test, established in International Shoe v. Washington, determines whether a defendant's contacts with a forum state are sufficient for personal jurisdiction

Jurisdictional Limitations and Forum Selection

• Subject matter jurisdiction limitations restrict where certain types of cases can be filed (exclusive federal jurisdiction over patent and copyright cases)
• Forum selection clauses in contracts can dictate where disputes will be heard, subject to reasonableness and public policy considerations
• Doctrine of forum non conveniens allows courts to dismiss or transfer cases when another forum is significantly more convenient for parties and witnesses

Diversity vs Federal Question Jurisdiction

Diversity Jurisdiction

• Requires complete diversity between plaintiffs and defendants and an amount in controversy exceeding $75,000
• Class Action Fairness Act (CAFA) modifies diversity jurisdiction requirements for certain class actions, allowing federal jurisdiction with minimal diversity
• Example: A California resident suing a New York corporation for $100,000 in damages

Federal Question Jurisdiction

• Arises when a case involves a substantial question of federal law, as determined by the well-pleaded complaint rule
• Artful pleading doctrine prevents plaintiffs from avoiding federal jurisdiction by omitting necessary federal issues from their complaints
• Complete preemption doctrine converts certain state law claims into federal claims when a federal statute wholly displaces the state law cause of action
• Example: A lawsuit alleging violation of federal environmental regulations or constitutional rights
