What is the difference between subject matter and personal jurisdiction?

Jurisdiction in personam (jurisdiction over the person)-

This refers to the power of a court over the person of a

defendant. The court may acquire such jurisdiction

when someone commits a crime, or performs an act

causing injury to another within the court's jurisdictional

area. By doing such acts, the person is said to

have consented to the court's jurisdiction.

• Jurisdiction of the subject matter-This refers to the

power of the court to hear the type of case. Courts of

general jurisdiction have subject matter jurisdiction over

felonies and cases of high value (commonly $25,000 or

more). Courts of limited jurisdiction (authorized to hear

only misdemeanors, for example) can't sit in judgment

in a murder case. They have no jurisdiction.
