Final answer:
The question deals with the concept of concurrent jurisdiction where both federal and state courts have the authority to hear certain types of cases.
Article III, Section 2 outlines the original and appellate jurisdiction of the Supreme Court, including cases involving state parties. Section 3 discusses the enforcement powers granted both to Congress and the states.
Step-by-step explanation:
Understanding Concurrent Judicial Authority
The mention of Article XVII(3)(a)(ii) and the reference to the right to exercise jurisdiction being concurrent pertains to situations where more than one legal authority may have the power to govern or legislate in certain cases. This often comes up in the context of federal and state law within the United States.
According to Section 2 of Article III, the Supreme Court has original jurisdiction over all cases affecting Ambassadors, other public Ministers and Consuls, and those in which a state is a party. However, for cases not specifically outlined under this original jurisdiction, the Supreme Court holds appellate jurisdiction. Concurrent jurisdiction means that both federal and state courts have the authority to hear certain types of cases.
Furthermore, Section 3 indicates that both Congress and the states have concurrent power to enforce articles of the Constitution through appropriate legislation. An example of this in action is the 19th Amendment where it states that both Congress and the states have the power to enforce the rights granted by the amendment.
