Apportion Election
The only case in California history where a district was created after a person had been elected to it. From the 1909 California Blue Book:
"The apportionment of May 1, 1851, provided for 27 Senators, and did not contemplate for a hold-over Senator in place of Adams, resigned. January 6, 1852 [a State Senate committee] reported that he was entitled to a seat, vice Adams, and he was qualified, thus increasing the membership of the Senate from 27 to 28."
