Insurers and their agents, while they are investigating suspected fraud claims, shall have access to all relevant public records that are required to be open for inspection under Division 10 (commencing with Section 7920.000) of Title 1 of the Government Code, and any regulations thereunder. This section restates existing law, and the Legislature does not intend to grant insurers or their agents access to public records other than to those public records available to them under existing law.
