In the early 1900s, the California State Legislature transformed the CDI into a law enforcement agency when it passed new anti-fraud insurance legislation.

On November 8, 1988, California voters passed Proposition 103, by a narrow margin (51%), on the promise of providing consumers with a 20% rate rollback.

In 2001, the CDI implemented and began overseeing the Slavery Era Insurance Registry, as per new legislation requirements signed into law in 2000.

The CDI issues cease and desist orders against service contract providers operating without the required legal documentation as part of its efforts to protect California consumers.

[2] The CDI, Enforcement Branch, is charged with responsibility of detecting, investigating and arresting those who commit insurance fraud, in order to protect the public from economic loss and distress.

In recent years, the some notable cases the Fraud Division has brought to prosecution are: The CDI publishes brochures and maintains a website to help consumers become aware of their rights, and to aid them in making informed insurance decisions.
