"The CPUC regulates privately owned electric, natural gas, telecommunications, water, railroad, rail transit, and passenger transportation companies. The CPUC serves the public interest by protecting consumers and ensuring the provision of safe, reliable utility service and infrastructure at reasonable rates, with a commitment to environmental enhancement and a healthy California economy. We regulate utility services, stimulate innovation, and promote competitive markets, where possible." - http://www.cpuc.ca.gov/
I would say that is a law enforcement agency. They are after all the agency responsible for ensuring that Über complies with state law relating to passenger transportation companies.
