What happens at a criminal law preliminary hearing?
Every individual who is charged by warrant is entitled to a preliminary hearing. If a person remains in jail, he or she is entitled to a preliminary hearing usually within 10 days of arrest. If a person is released from jail on bond, he or she is entitled to a preliminary hearing usually within 30 days of arrest.

A preliminary hearing is an examination of the charge against the accused. The prosecutor must present evidence and witnesses that prove an offense has been committed, and that there is probable cause to believe that the accused committed the offense. The accused may cross-examine witnesses, and may present evidence if he or she chooses.

If the judge finds probable cause after hearing the evidence, the charge is sent to the grand jury. If the judge does not find that an offense appears to have been committed, or that the accused is not likely the person who committed the offense, the accused is released and the charge is dismissed. 

What is the sentencing hearing?
Except for minor offenses, such as infractions, a sentencing hearing is held where the final sentence or penalty is determined. The character of and circumstances surrounding the defendant can be as important as the severity of the crime, in determining what sentence will be imposed.

At the sentencing hearing, both the prosecution and the defense are given the opportunity to present evidence and testimony to recommend an appropriate sentence. The judge is free to ignore these recommendations, even if the prosecutor and defense lawyer have agreed to a sentence as a part of a plea agreement.
