Much of the Government of California is in practice the responsibility of local governments such as the Government of Los Angeles County. The county's voters elect a governing five-member Los Angeles County Board of Supervisors. The small size of the board means each supervisor represents over 2 million people. The board operates in a legislative, executive, and quasi-judicial capacity. As a legislative authority, it can pass ordinances for the unincorporated areas (ordinances that affect the whole county, like posting of restaurant ratings, must be ratified by the individual city). As an executive body, it can tell the county departments what to do, and how to do it. As a quasi-judicial body, the Board is the final venue of appeal in the local planning process, and holds public hearings on various agenda items. As of 2020, the Board of Supervisors oversees a $35.5 billion annual budget and over 112,000 employees. The county government is managed on a day-to-day basis by a Chief Executive Officer and is organized into many departments, each of which is enormous in comparison to equivalent county-level (and even many state-level) departments anywhere else in the United States. Some of the larger or better-known departments include: * Los Angeles County Department of Consumer and Business Affairs – offers consumers in the county a variety of services including: consumer and real estate counseling, mediation, and small claims counseling investigates consumer complaints, real estate fraud and identity theft issues. The department also provides small business certifications and helps entrepreneurs navigate the process of opening a business. * Los Angeles County Department of Children and Family Services – administers foster care * Los Angeles County Fire Department – provides firefighting services for the unincorporated parts of Los Angeles County, as well as 58 cities. *

Legal system

The Los Angeles County Superior Court is the county's court of general jurisdiction, while the U.S. District Court for the Central District of California may hear cases where federal jurisdiction is present. Both are headquartered in a large cluster of government buildings in the city's Civic Center. Historically, the courthouses were county-owned buildings that were maintained at county expense, which created significant friction since the trial court judges, as officials of the state government, had to lobby the county Board of Supervisors for facility renovations and upgrades. In turn, the state judiciary successfully persuaded the state Legislature to authorize the transfer of all courthouses to the state government in 2008 and 2009 (so that judges would have direct control over their own courthouses). Courthouse security is still provided by the county government under a contract with the state. Unlike the largest city in the United States, New York City, all of the city of Los Angeles and most of its important suburbs are located within a single county. As a result, both the county superior court and the federal district court are respectively the busiest courts of their type in the nation. Many celebrities have been seen in Los Angeles courts. In 2003, the television show ''Extra'' (based in nearby

) found itself running so many reports on the legal problems of local celebrities that it spun them off into a separate show, ''Celebrity Justice''. State cases are appealed to the Court of Appeal for the Second Appellate District, which is also headquartered in the Civic Center, and then to the California Supreme Court, which is headquartered in San Francisco but also hears argument in Los Angeles (again, in the Civic Center). Federal cases are appealed to the
