Where does jurisdiction collide?

In procedural law, jurisdiction is a court's legal power to hear a particular case and to render a binding judgment: it comes in two forms, authority over the type of dispute (subject-matter jurisdiction) and authority over the parties (personal jurisdiction), and a court that lacks either cannot decide. The 1945 decision in International Shoe Co. v. Washington set the modern American test, holding that a court may exercise power over an out-of-state defendant only where that defendant has certain minimum contacts with the forum, so that the suit does not offend traditional notions of fair play. Here the word names an abstract, relational competence that a tribunal either holds or lacks for a given lawsuit, established or defeated case by case. That is different from a mapped territory a government administers, from a profession's claim over a body of work, and from the spiritual power of a church officer.[3][1]

In the sociology of professions, jurisdiction is the link between a profession and the work it claims the exclusive right to perform, and professions compete for it inside a connected system. Abbott's 1988 The System of Professions made this the central idea: an occupation asserts jurisdiction over a set of tasks, defends it in the workplace, in public opinion, and before the law, and wins or loses ground as rivals press competing claims, so that gains by one profession force settlements on its neighbours. Here the word names a contested claim of occupational control, a relationship between a group of workers and a domain of expert labour. That is not a court's power to decide a case, not a governed patch of land, and not a church officer's authority over souls.[2]
