Who Issues Warrants in Portsmouth
In New Hampshire an arrest warrant is signed by a judge. For Portsmouth that means the Rockingham County Superior Court, which hears felonies, civil cases tried to a jury, and appeals; the Circuit Court issues its own warrants on the cases before it.
A bench warrant follows a missed court date in any of those courts. Whichever kind it is, the warrant is part of the file of the case it was issued in, and the clerk of each court keeps that file.
