Role of The District Attorney's Office
The prosecution of crimes in Pennsylvania is delegated to local government officials.
Pennsylvania is comprised of 67 counties. Each county has a District Attorney and
a Court of Common Pleas. Jurisdiction over crimes committed in a county falls to
the Court of Common Pleas. In Allegheny County, as in all counties in Pennsylvania,
there is also a minor judiciary. Magisterial District Judges preside in the courtrooms
of the minor judiciary, throughout Allegheny County. The first steps of any criminal
prosecution take place before the minor judiciary.
