How a case moves here

Delaware County follows Pennsylvania law on arrests, release, and courts. These rules are the same in every county in the state; the full set covers prosecutors, defense, and jails too.

Who decides release first

Outside Philadelphia, a magisterial district judge sets bail at the preliminary arraignment. In Philadelphia, an arraignment court magistrate appointed by the Municipal Court sets it; magistrates need not be lawyers if they complete a training program. Neither may set bail for murder or voluntary manslaughter; a Common Pleas judge does.

Time to see a judge

A person arrested without a warrant must have a preliminary arraignment without unnecessary delay. The rule sets no hour limit. The U.S. Supreme Court's 48-hour rule for a probable cause finding applies as the federal floor.

Pa.R.Crim.P. 516(A)
Money bail

Money bail is allowed. The rules list five kinds of release, from release on recognizance to a money condition no larger than needed to ensure the person appears.

Pa.R.Crim.P. 524(C)
Courts

The Court of Common Pleas, organized in 60 judicial districts, tries felonies and misdemeanors. Magisterial district judges hear summary offenses, the lowest grade, and hold first arraignments and preliminary hearings. In Philadelphia, the Municipal Court tries crimes punishable by up to five years without a jury.

Judges and magistrates

Common Pleas judges win a contested election for a 10-year term, then run in yes-or-no retention elections without party labels. Magisterial district judges are elected in contested elections to six-year terms and need not be lawyers. All other judges must be members of the bar.
