Answer: The preliminary hearing typically occurs between ten and fourteen days after arrest.  A preliminary hearing (also known as a “probable cause” hearing, or “commitment” hearing) is a proceeding where the prosecutor must establish in court that they have enough evidence to detain the individual on the filed charges (i.e. warrant).  The hearing is designed primarily for the benefit of those incarcerated individuals who have been unable to post bond, to ensure that they are not held in jail on unfounded charges.  However, individuals out on bond are also permitted to request a preliminary hearing, and as a general rule an attorney should request one in almost every felony case regardless of whether the defendant is in jail.
