A preliminary hearing is usually held shortly after the arrest (a week to 10 days). It is generally a simple and brief procedure which takes place only in cases where there are felony charges. The victim/witness testifies to the basic facts of his/her assault. Then the judge decides whether there is enough evidence to move the case to trial. At the preliminary hearing charges may be added or dropped depending on the attorney. Bail may be raised, lowered or remain the same.
