How a case moves here
Derry follows Pennsylvania law on arrests, release, and courts; 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.
Pa.R.Crim.P. 51942 Pa.C.S. 1515(a)(4)42 Pa.C.S. 1123(a)(5)- 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)
Read from the statutes and court rules cited, 2026-09-30. The prison board statute covers counties of the third to fifth class and those that opt in; Philadelphia and Allegheny run jails under other arrangements not read here.
