==Law, government, and politics== ===Government=== {{Main|Government of Los Angeles County}}

[[Image:Arthur J. Will Memorial Fountain.jpg|thumb|right|The [[Kenneth Hahn Hall of Administration]] is the seat of the [[government of Los Angeles County]].]] The [[Government of Los Angeles County]] is defined and authorized under the [[California Constitution]], [[California law]] and the Charter of the County of Los Angeles.<ref>California Government Code § 23004</ref> 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{{nbsp}}million people. The board operates in a legislative, executive, and [[Quasi-judicial body|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{{nbsp}}billion annual budget and over 112,000 employees.<ref>Sachi A. Hamai, [https://ceo.lacounty.gov/wp-content/uploads/2020/04/1.-2020-21-Recommended-Budget-Transmittal-Letter.pdf Transmittal Letter, Fiscal 2020–21 Recommended County Budget] {{Webarchive|url=https://web.archive.org/web/20200522085245/https://ceo.lacounty.gov/wp-content/uploads/2020/04/1.-2020-21-Recommended-Budget-Transmittal-Letter.pdf |date=May 22, 2020 }}, April 28, 2020, 2.</ref> 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:

The cities of [[Long Beach, California|Long Beach]] and [[Pasadena, California|Pasadena]] have their own autonomous Public Health departments assuming county functions, and county public health orders are not applicable in those cities. * Los Angeles County Department of Public Social Services – administers many federal and state welfare programs * [[Los Angeles County Department of Public Works]] – operates countywide flood control system, constructs and maintains roads in unincorporated areas. * [[Los Angeles County District Attorney]] – prosecutes criminal suspects. * [[Los Angeles County Public Defender|Los Angeles County Office of the Public Defender]] – defends indigent people accused of criminal offenses. * [[Los Angeles County Probation Department]] * [[Los Angeles County Sheriff's Department]] – provides law enforcement services for the unincorporated parts of Los Angeles County, as well as 42 cities.

On November 4, 2008, Los Angeles County was almost evenly split over [[California Proposition 8 (2008)|Proposition 8]], which amended the California Constitution to ban same-sex marriages. The county voted for the amendment 50.04% with a margin of 2,385 votes.<ref>{{Cite web |url=http://www.sos.ca.gov/elections/sov/2008_general/sov_complete.pdf |archiveurl=https://web.archive.org/web/20121018225250/http://www.sos.ca.gov/elections/sov/2008_general/sov_complete.pdf|title="Statement of Vote: 2008 General Election" |archivedate=October 18, 2012}}</ref>

===Legal system=== {{further|Los Angeles County Superior Court}}

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.<ref>''A look at your Superior Court'', Public Information Office, Los Angeles Superior Court</ref><ref>{{cite web |url=http://www.lasuperiorcourt.org/aboutcourt/history.htm |title=LA Court |work=lasuperiorcourt.org |url-status=dead |archive-url=https://web.archive.org/web/20090219135841/http://lasuperiorcourt.org/aboutcourt/history.htm |archive-date=February 19, 2009}}</ref>

Many celebrities have been seen in Los Angeles courts. In 2003, the television show ''Extra'' (based in nearby [[Glendale, California|Glendale]]) 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, Los Angeles|Civic Center]], and then to the [[Supreme Court of California|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 [[United States Court of Appeals for the Ninth Circuit|Court of Appeals for the Ninth Circuit]], which hears them at its branch building in [[Pasadena, California|Pasadena]]. The court of last resort for federal cases is the [[Supreme Court of the United States|U.S. Supreme Court]] in [[Washington, D.C.]]

===Rail=== Los Angeles is a major freight-railroad transportation center, in great part due to the large volumes of freight moving in and out of the county's seaport facilities. The ports are connected to the downtown rail yards and to the main lines of [[Union Pacific]] and [[Burlington Northern Santa Fe]] headed east via a grade-separated freight rail corridor known as the [[Alameda Corridor]].

Passenger rail service is provided in the county by [[Amtrak]], [[Los Angeles Metro Rail]] and [[Metrolink (California)|Metrolink]].

Amtrak has the following intercity Amtrak service at [[Los Angeles Union Station|Union Station]] in the city of Los Angeles: * The ''[[Pacific Surfliner]]'' to [[Santa Barbara, California|Santa Barbara]], [[San Luis Obispo]], and [[San Diego]]. * The ''[[Coast Starlight]]'' to [[San Francisco Bay Area]], [[Portland, Oregon|Portland]] and [[Seattle]]. * The ''[[Southwest Chief]]'' to [[Albuquerque, New Mexico|Albuquerque]], [[Kansas City, Missouri|Kansas City]] and [[Chicago]]. * The ''[[Sunset Limited]]'' to [[Tucson, Arizona|Tucson]], [[Houston]] and [[New Orleans]].

Union Station is also the primary hub for Metrolink commuter rail, which serves much of the [[Greater Los Angeles Area]].

Light rail, subway (heavy rail), and long-distance bus service are all provided by the [[Los Angeles County Metropolitan Transportation Authority]] (Metro). Other smaller regional transit agencies that provide public transit to specific regions of Los Angeles County include [[LADOT]], [[Long Beach Transit]], [[Montebello Bus Lines]], [[Norwalk Transit (California)|Norwalk Transit]], [[Santa Monica]]'s [[Big Blue Bus]] serving the [[Westside (Los Angeles County)|western LA region]], [[Santa Clarita Transit]], [[Torrance Transit]], [[Glendale Beeline]], [[Foothill Transit]] serving the [[San Gabriel Valley]] region, and the [[Antelope Valley Transit Authority]] serving the [[Lancaster, California|Lancaster]] and [[Palmdale, California|Palmdale]] area in the [[Antelope Valley]] region.

===Sea=== The county's two main seaports are the [[Port of Los Angeles]] and the [[Port of Long Beach]]. Together they handle over a quarter of all [[containerization|container]] traffic entering the United States, making the complex the largest and most important port in the country, and the third-largest port in the world by shipping volume.

The Port of Los Angeles is the largest cruise ship center on the [[West Coast of the United States|West Coast]], handling more than 1{{nbsp}}million passengers annually.

The Port of Long Beach is home to the [[Sea Launch]] program, which uses a floating launch platform to insert payloads into orbits that would be difficult to attain from existing land-based launch sites.

[[Catalina Express]] ferries link the Catalina Island city of [[Avalon, California|Avalon]] to the mainland at [[San Pedro, Los Angeles|San Pedro]] and [[Long Beach, California|Long Beach]], as well as [[Dana Point, California|Dana Point]] in [[Orange County, California|Orange County]].
