Although the legal assistant must be familiar with all aspects of the American legal system, the practice of law typically revolves around the judicial branch. The function of the judicial branch is to apply law to facts in resolving disputes between adversaries, which is accomplished through the trial and appellate processes.
Each legal system has its own judicial branch, which operates through a system of courts. A court is classified by the system in which it operates and by the types of cases which it is authorized to hear. These classifications are part of a court’s jurisdiction. Jurisdiction is the power or authority of a court to hear a specific case. Both subject matter jurisdiction and personal jurisdiction must exist before a court can decide the merits of a particular case.
Subject Matter Jurisdiction
Subject matter jurisdiction relates to the type of case in which a court is authorized to hear. If a court does not have subject matter jurisdiction, it lacks the power to decide the merits of the case. In that situation, any action taken by it is void; it has no effect whatsoever. Because it relates to a court’s power to act, subject matter jurisdiction never can be waived.
Limited or General Jurisdiction
Every court is either a court of limited jurisdiction or a court of general jurisdiction. No court can be both. Limited Jurisdiction means that the court cannot hear every type of case presented to it; it can hear only those types of cases which are listed in its creating constitutional provision or statute. Because of the federal government is one of limited powers, every federal court is a court of limited jurisdiction.
General Jurisdiction means that the court can hear any type of case presented to it unless exclusive jurisdiction has been granted to some other court for a particular type of case. Every state has at least one court of general jurisdiction, sometimes called a district or superior court.
Original or Appellate Jurisdiction
Every court is either a court of original jurisdiction or a court of appellate jurisdiction, but some courts are both. Original Jurisdiction means that actions are commenced in this court for particular types of cases. A court of original jurisdiction is the trial court for those types of cases specified in its creating constitutional provision or statute.
Appellate Jurisdiction means that the court is authorized to review decisions of an inferior court in certain types of cases. A single court may have original jurisdiction in one type of case and appellate jurisdiction in another type of case.
Concurrent Jurisdiction
Concurrent jurisdiction means that more than one court is authorized to hear a specific type of case. This allows a plaintiff to choose between those courts having concurrent jurisdiction of the subject matter of the case.
Personal Jurisdiction
A court must have both subject matter jurisdiction and personal jurisdiction, some times called in personam jurisdiction, before it can hear and decide the merits of a particular case.
Personal Jurisdiction refers to the court’s power or authority over the parties to the litigation.
A court acquires personal jurisdiction over a plaintiff when they file their complaint or petition. Personal jurisdiction over a defendant usually can be acquired with one of the following ways.
- Defendant’s consent;
- Defendant’s domicile in the same state where the action is file;
- Long-arm statutes
