Final answer:
The subject of the question is jurisdiction in the U.S. legal system, specifically SMJ and PJ. SMJ refers to a court's authority over a particular type of case, while PJ refers to a court's authority over the parties involved. SMJ can be based on federal law, while PJ is based on the defendant's contacts with the forum state.
Step-by-step explanation:
The subject of the question pertains to jurisdiction in the United States legal system, specifically regarding Subject Matter Jurisdiction (SMJ) and Personal Jurisdiction (PJ).
Subject Matter Jurisdiction refers to the authority that a court has to hear cases of a particular type or subject matter. It is determined by the type of claim or issue being raised in the case. For example, if the claim involves a federal question or a claim arising under federal law, federal courts would have subject matter jurisdiction.
Personal Jurisdiction, on the other hand, refers to the authority that a court has over the parties involved in a case. It is based on the court's power to exercise control over the individuals or entities that are being sued. Personal Jurisdiction can be established if the defendant has sufficient contacts with the forum state, such as living or doing business there.
