What does "jurisdiction" refer to in legal terms?

Jurisdiction in legal terms refers to the authority granted to a court to hear and decide cases. This concept ensures that a court has the power over the parties involved and the subject matter of the case. Effective jurisdiction is crucial, as it dictates whether a court can proceed with a case or if the case should be heard elsewhere. For instance, a court's jurisdiction can be limited by geographic boundaries, the nature of the legal issue, or the amount of money involved in civil cases. Understanding jurisdiction helps in determining the appropriate venue for legal disputes and ensures that cases are adjudicated within the correct legal framework. This foundational concept underpins the functioning of the judicial system, making it essential for legal practitioners and anyone involved in the legal process.
