Full Text of Art. 1
Plain-English Summary
Every lawsuit needs a court with the power to hear it. Article 1 supplies the baseline definition: jurisdiction is a court's legal power and authority to hear and determine a case, and to grant whatever relief the winning party deserves. Without it, nothing that follows in a case carries any legal weight.
Louisiana breaks this single idea into several distinct pieces, unlike states that treat jurisdiction as one common-law concept. The articles that follow separate jurisdiction over the subject matter (Article 2), over the person (Article 6), over property (Article 8), and over status — things like marriage, adoption, and custody (Article 10). Each kind answers a different question: can this court hear this type of case, reach this defendant, control this property, or decide this person's legal status?
A court needs the right kind of jurisdiction for what it's being asked to do. A small claims court might have subject-matter jurisdiction over a modest debt dispute but no power over a custody fight. A Louisiana court might have jurisdiction over property located in the state even when it has no power to reach the out-of-state owner personally. Article 1 is the anchor point for all of it.
Frequently Asked Questions
What does ‘jurisdiction’ mean in a Louisiana lawsuit?
It means the court has the legal power and authority to hear the case and to award the relief a party is entitled to. Without it, any judgment the court issues carries no legal force.
Why does Louisiana split jurisdiction into so many categories?
Because different aspects of a case can call for different kinds of power. A court may decide a person's marital status without being able to reach that person personally, or may control property in the state without reaching its nonresident owner. Louisiana's Code spells out each category separately rather than treating jurisdiction as one blanket concept.
Can a court have jurisdiction over the type of case but not over the defendant?
Yes. Subject-matter jurisdiction (the power to hear that category of case) and jurisdiction over the person (the power to bind a specific defendant) are separate requirements, and a court needs both before it can enter a valid personal judgment.
Is jurisdiction the same thing as venue?
No. Jurisdiction asks whether a court has the power to decide the case at all; venue asks which parish is the proper place to bring it. A court can have full jurisdiction over a case and still be the wrong venue.
