Jurisdiction - technical definition

Jurisdiction and power accorded to judges are intimately related. Power is constitutionally conferred on a judge to decide whether there has been a breach of law, the causes of the breach, and the kind of prison sentence or penalty that is appropriate for such a breach. The physical land area or geographical district within which a judge has jurisdiction is called his or her “territory.” Thus, a judge’s power relative to the territory is called “the territorial jurisdiction.” Judges have power only in their jurisdictions, and the decisions of judges in upper courts preside over decisions of judges in inferior courts.
