Last time, we reviewed which Districts and Divisions of the Court of Appeal produced the Supreme Court’s civil and criminal dockets.  This week, we’re drilling down a bit more and looking at the originating trial courts.  Since we reviewed this data about eighteen months ago, we’re looking at it this time in a slightly different way – five years at a time, which of the counties assigned to each District produced the Court’s cases.  We begin with the First District.

Twelve counties are assigned to the First District: Alameda, Contra Costa, Del Norte, Humboldt, Lake, Marin, Mendocino, Napa, San Francisco, San Mateo, Solano and Sonoma.  To make the comparison to case numbers easier, we calculate population as a percentage of the total population of the District’s counties, using the 2010 census.  Alameda county accounts for 26.57% of the District’s population.  Contra Costa county is 18.45%.  San Francisco county is 14.16% and San Mateo county is 12.64%.  Sonoma county is 8.51% of the District’s population, Solano is 7.27%, Marin is 4.44%, Napa is 2.4%, Humboldt is 2.37%, Mendocino is 1.55%, Lake is 1.14% and Del Norte county accounts for 0.5% of the District.

In 1990, the Court decided three civil cases from San Francisco, two from Alameda and Contra Costa and one each from San Mateo and Sonoma counties.  In 1991, the Court decided two cases from San Francisco and one apiece from San Mateo, Solano, Alameda and Contra Costa.  The following year, the Court decided five cases from San Francisco, two each from Alameda and Contra Costa and one from San Mateo.  In 1993, the Court decided two cases from San Francisco and one each from Alameda, Solano and Sonoma. In 1994, the Court decided four cases from San Francisco, three from Marin and one each from Contra Costa, Humboldt, Lake, Mendocino, San Mateo, Solano and Sonoma counties.

In 1995, the Court decided eight civil cases from San Francisco, two apiece from Alameda, Contra Costa and San Mateo, and one each from Marin, Napa and Solano counties.  In 1996, the Court decided three cases from San Francisco, two from Mendocino and San Mateo and one from Alameda and Marin.  In 1997, the Court decided four cases from San Mateo county, three from Alameda, two each from San Francisco and Solano counties and one from Marin.  In 1998, the Court decided five cases from San Francisco, three from Alameda, two from Solano and one case from Contra Costa, Lake and San Mateo.  In 1999, the Court decided three cases from San Francisco county and one each from Alameda, Lake, Marin and Sonoma.

In 2000, the Court decided six civil cases from San Francisco and one each from Marin, San Mateo and Sonoma.  In 2001, the Court decided four cases from San Francisco and one from Marin.  In 2002, the Court decided six cases from San Francisco and one each from Contra Costa, Marin, San Mateo and Sonoma.  In 2003, the Court decided five cases from San Francisco, two each from Sonoma and Contra Costa and one from Alameda.  In 2004, the Court decided seven civil cases from San Francisco and one from Contra Costa.

Join us back here next time as we review the data for the years 2005 to 2019.
