What is jurisdiction?
Jurisdiction is the power of a court to hear a case and make a binding decision over the parties and the subject matter.
Jurisdiction is a court’s authority to hear a case and bind the parties.
Where the word "Jurisdiction" comes from
Jurisdiction comes from the Latin jurisdictio, the saying of the law. It defines which court can act, covering both the court's authority over the type of case and its power over the specific parties, and it is the first question every case raises.
Why Jurisdiction matters
A court without jurisdiction cannot enter a valid judgment, no matter how strong the claim. Checking jurisdiction before filing saves wasted time and money, because a case filed in the wrong court is dismissed or transferred.
Common confusion about Jurisdiction
Subject matter jurisdiction and personal jurisdiction are different. Subject matter jurisdiction concerns the type of case, such as federal versus state; personal jurisdiction concerns the court's power over the defendant, which can depend on where the defendant lives or does business.
A real-world example of Jurisdiction
A California resident sues a Texas company over an online purchase. The court must decide whether it has personal jurisdiction over the Texas company, based on the company's contacts with California, before the case can proceed.
A worked example of Jurisdiction
A buyer in New York sues a small seller in Oregon over a one-time online sale. The seller has no contacts with New York beyond that single transaction, so a New York court may lack personal jurisdiction and dismiss the case, forcing the buyer to sue in Oregon. Conversely, a contract dispute under federal law with parties from different states may belong in federal court, so the analysis involves both the claim type and the parties' locations.
How Jurisdiction works in practice
Before filing, determine which court has both subject matter and personal jurisdiction, and consider the defendant's location, because a judgment from a court without jurisdiction is unenforceable. If you are sued in a distant court, challenge jurisdiction early, because appearing without objection can waive the defense. Ask a local attorney about venue and jurisdiction rules, since the details vary by court system. In federal court, jurisdiction may depend on the amount in controversy and the diversity of the parties' states, while state courts usually base jurisdiction on where the parties live or where the events occurred, so the analysis is different in each system.
