Jurisdiction is the legal power or authority to make decisions, judgments, or laws in a particular area or over certain people. It can refer to both a place and a type of case a court is allowed to handle.
From Latin “iurisdictio” meaning “the saying of the law”, from “ius” (law) and “dicere” (to say). It originally described the act of declaring legal rules, then the area where that power applied.
Jurisdiction is like an invisible fence around a court’s power: inside it, decisions count; outside it, they’re just opinions. Modern life is full of overlapping jurisdictions—national, local, online platforms—all quietly competing to be the voice of the law.
