The individuals granted pardons all completed their sentences and have been released from custody for more than a decade without further criminal activity.
Individuals who have been convicted of a crime in California may apply to the Governor for a pardon. Most applicants for a pardon have obtained a Certificate of Rehabilitation, which is an order from a superior court declaring that a person convicted of a crime is now rehabilitated. A gubernatorial pardon may be granted to people who have demonstrated exemplary behavior and have lived productive and law-abiding lives following their conviction. Pardons are not granted unless they are earned.
When a pardon is granted, the California Department of Justice and the Federal Bureau of Investigation are notified so that they may update their records on the applicant. The pardon is filed with the Secretary of State and the Legislature, and it is a public record.
