What term refers to the power to adjudicate or handle particular types of cases?

The term that refers to the power to adjudicate or handle particular types of cases is "Jurisdiction." This concept is fundamental in the legal system as it defines the scope and limits of a court's authority to make legal decisions and judgments. Jurisdiction can be categorized in various ways, such as geographical, subject matter, or personal jurisdiction, indicating what types of cases a court can hear.

Understanding jurisdiction is essential for both legal professionals and individuals interacting with the legal system, as it establishes where a case can be properly filed and which court has the authority to decide on specific issues. The concept ensures that cases are heard in appropriate forums, thereby maintaining the integrity and efficiency of the judicial process.

The other terms listed, while related to legal principles, do not specifically convey the idea of authority over certain types of cases. For example, "Authority" is a broader term regarding power or rights granted, "Adjudication" refers to the legal process of resolving a dispute or deciding a case, and "Power of Attorney" is a legal document giving one person the authority to act on behalf of another. Hence, "Jurisdiction" is the precise term that captures this notion aptly.
