The way cases move through the criminal justice system can be confusing. This animation shows how a case begins (with a crime being committed) and the path it takes to its conclusion. It also illustrates the checks and balances in place to ensure fair and equal justice is delivered.

A police officer may arrest someone on the spot if they have probable cause to believe a misdemeanor or felony crime has been committed. An arrest warrant is required in some situations. The officer will submit a request to the District Attorney’s Office requesting a formal complaint and a warrant. At this time, a District Attorney victim advocate will be assigned to the victim or to the victim’s family to connect them to services, to help them understand the criminal justice system and to guide them through the process. In California, victims have the right to be present during every hearing and shall be allowed to address the Judge at sentencing.

Suspect Arrested (If Not In Custody)
Suspect Arrested (If Not In Custody)
This is the defendant’s first court appearance. They are informed of the charges, advised of their constitutional rights and appointed an attorney. This is when the defendant pleads guilty or not guilty to the charges or pleads No Contest, which is when a defendant is convicted and receives his/her sentence but does not admit guilt.

Arraingement
If the defendant is charged with a misdemeanor and pleads guilty or no contest, the Judge may sentence them at that time or schedule the case for a future sentencing date. If the defendant pleads not guilty, the case will be scheduled for a pretrial conference. At a felony arraignment, the defendant enters a plea, and is advised of their constitutional right to a preliminary examination within 10 days.
If the defendant is charged with a misdemeanor and pleads guilty or no contest, the Judge may sentence them at that time or schedule the case for a future sentencing date.
Misdemeanor/Felony
The defendant’s attorney may cross examine each of these witnesses and present their own evidence of innocence.  If probable cause is established, the defendant is bound over for trial. If the Judge decides there is not probable cause the defendant committed the crime, the charge may be dismissed or reduced to a misdemeanor.
If the defendant is charged only with misdemeanor crimes, there will be no preliminary hearing. Misdemeanor cases proceed to a pretrial proceeding and trial after arraignment.
This is when the DDA presents witnesses to convince the judge there is probable cause to believe a felony offense was committed. Generally, this is when the victim, and/or eyewitnesses, and the police officer may testify.
Preliminary Hearing
2nd Arraignment
After the case is bound over for trial, the defendant is given formal notice of the charges during an arraignment. The charging document is called an information. The defendant is again advised of their constitutional rights and enters a plea to the charge (guilty, not guilty, no contest).
2nd Arrangement
Pretrial Proceedings
During these hearings, the Judge is called upon to resolve various issues such as whether the case should continue to trial, be resolved with a change of plea, or be dismissed.
Pretrial Proceedings
A trial is an adversarial proceeding in which the DA must present evidence to prove the defendant's guilt beyond a reasonable doubt. The defendant is represented by an attorney and if they can't afford an attorney, one will be provided at no cost. The defendant is not required to prove their innocence or to present evidence, but their attorney may challenge the evidence presented by the DA. After all evidence is presented, the Judge or jury will determine whether the evidence proved the defendant committee a crime. If they are found guilty, a sentencing date will be set.

Trial (Judge or Jury)
The Probation Department prepares a report for the Judge summarizing the crime, the defendant’s criminal record, and sometimes contacts the victim/s for a recommended sentence. The final phase is the sentencing and it can be the most confusing. Most often, sentences are at the judge’s discretion. The Judge takes into consideration Probation’s pre-sentencing report and listens to additional information from parties at this time. It is during this phase of the process the victim or the victim’s family may address the court to describe the trauma and harm the defendant’s behavior has caused them. The Judge will also consult “sentencing guidelines” in the California Rules of Court, which aids the court in deciding the appropriate sentence.  However, the Judge may consider different alternatives; fines, probation, community service, jail or prison. The Judge must order the defendant to pay restitution to any victims who have suffered harm.
