Chapter 1. Seat Of Government

450.  The permanent seat of government of the state is at the City
of Sacramento, but the Governor shall designate by written
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
directed by him, shall provide such facilities of any kind at the
temporary seat of government as appear desirable for the functioning
of the government of the state at the temporary seat of government in
the event it becomes necessary, pursuant to this section.
