2009 California Government Code - Section 450 :: Chapter 1. Seat Of Government

450.  The permanent seat of government of the state is at the City

proclamation an alternative temporary seat of government for use in
the event of war or enemy-caused disaster, or the imminence thereof.
The proclamation shall be filed with the Secretary of State. A
different temporary seat of government may be so designated at any
time as circumstances indicate the desirability of such a change.
   The Director of General Services, and any other state agency as

of the government of the state at the temporary seat of government in
the event it becomes necessary, pursuant to this section.
