Although it is rare, it is possible for charges to be dropped at an arraignment. This may happen through a probable cause hearing, which typically occur during an arraignment. A probable cause hearing is made after a criminal defense lawyer Los Angeles, CA requests a judge to hold this type of hearing.
During a probable cause hearing, a judge will determine if there is probable cause to believe that a crime was committed and that you were the person who committed that crime. These hearings are held in cases where a person was arrested on a misdemeanor crime without a warrant and then are held in custody at the time of arraignment. If a judge finds that there is no probable cause, then the charges could be dropped.
