§ 1297.431.Immunity While Present In State For Conciliation Purposes

Getting people to the table for conciliation is harder if showing up means risking a process server at the door. This section removes that risk. While the conciliator or conciliators, the parties, and their representatives are present in California for the purpose of arranging for or participating in conciliation under this title, none of them can be served with process in any civil matter.

The protection is tied specifically to that purpose and that presence -- it isn't a general immunity from being sued, just a shield against being served while physically in the state to make conciliation happen. That narrow but practical protection encourages out-of-state parties and their representatives to travel to California for conciliation without fear that the trip itself becomes an opportunity for someone to serve them with unrelated litigation papers.
