United States District Court for the Northern District of California
The United States District Court for the Northern District of California, cited in legal papers as N.D. Cal., is a federal trial court headquartered in San Francisco. Its name sounds like a regional courthouse, yet its caseload is tied closely to one of the most powerful industries on earth. This documentary asks a handful of questions. Why do so many disputes involving technology companies end up before this court? How did a court created in the opening months of California statehood arrive at that position? How did its borders shift, merge, and split over the following century? And who has stood in its courtrooms to represent the federal government?
Fifteen California counties fall under the court's authority, running alphabetically from Alameda to Sonoma. The full list is Alameda, Contra Costa, Del Norte, Humboldt, Lake, Marin, Mendocino, Monterey, Napa, San Benito, San Francisco, San Mateo, Santa Clara, Santa Cruz, and Sonoma. Judges hear cases in courtrooms in four cities: Eureka, Oakland, San Francisco, and San Jose. When a party loses at this level and wants a second look, the case goes up to the United States Court of Appeals for the Ninth Circuit.
San Francisco and Silicon Valley both sit inside this court's territory, and that overlap shapes everything about its modern reputation. Large class actions and multi-district litigation against "Big Tech" defendants have become presumptive business for the court. Many of these cases turn on patent law and other intellectual property questions. Those include copyright, DMCA disputes, trademarks, and trade secrets, especially in semiconductors, telecommunications, and software. Antitrust and securities law also appear often. So does technology law in the broad sense, covering cybersecurity, internet law, computer law, and software cases. The foundations of this role were laid in the middle of the nineteenth century.
On the 9th of September 1850, California became a state, and Congress moved quickly to give it federal courts. An act approved on the 28th of September 1850, recorded at 9 Stat. 521, divided the new state into a Northern and a Southern district. The dividing line followed the 37th parallel of North Latitude. The act also gave each court powers beyond those of an ordinary district court, modeled on the Southern District Court of New York. Each could exercise concurrent jurisdiction with the Circuit Courts of the United States in civil cases. Appeals from those judgments could go directly to the Supreme Court of the United States. Within two years, Congress began to blur the line it had just drawn.
The Act of the 31st of August 1852, found at 10 Stat. 76, 84, made the judge of the Northern District the judge of the Southern District as well. That arrangement lasted only until Congress provided otherwise, which meant California had a single district in all but name. An act of the 18th of January 1854 supplied a separate judge for the Southern District. The separation did not last. On the 27th of July 1866, an act recorded at 14 Stat. 300 abolished the Southern District and made the whole state one court, the United States District Court for the District of California. Twenty years later, Congress reversed course again.
On the 5th of August 1886, Congress re-created the Southern District of California through 24 Stat. 308. Erskine M. Ross was appointed judge of the new district. He served there until he was promoted to the Circuit Judgeship, and Olin Wellborn succeeded him. A much larger change came on the 18th of March 1966, when 80 Stat. 75 created the Eastern and Central Districts. Both were carved out of portions of the Northern and Southern Districts, so the Northern District gave up territory in the process. The court's judges changed over the decades, and so did the lawyers who appeared on the government's side.
Calhoun Benham opens the long list of United States attorneys for the Northern District, serving from 1850 to 1853. He returned to the post from 1860 to 1861. Joseph P. Russoniello also served twice, from 1981 to 1990 and again from 2008 to 2010. The office represents the United States in both civil and criminal litigation before the court. Robert S. Mueller held it from 1998 to 2001, and Melinda Haag led it from 2010 to 2016. Some names on the roll are brief appearances. Frank M. Pixley served only in 1869, and B. L. McKinley only in 1913. The 2025 entries show the office changing hands repeatedly in a single year, passing from Ismail Ramsey to Patrick D Robbins in an acting role, and then to Craig H. Missakian.
