Legal Question in Workers Comp in California

The Labor Code requires copies of MEDICAL EVIDENCE and MEDICAL REPORTS but not necessarily all correspondence. I don't get copies of correspondence between the defense attorney and billing staff at the clinic -- I have to ask the clinic for copies to prepare my penalty petitions. The person 'in possession and control' of evidence -- EVIDENCE -- is required to 'serve' it in 14 days from receipt, but a letter typically doesn't rise to the level of evidence until there is an active dispute. YOU CAN write to the defense attorney, the doctor's office and the insurer and demand to be included in the Official Address Record for copies of all written communications, and send it with a Proof of Service, but the trouble is if it doesn't work there isn't a penalty for not getting the correspondence. IF YOU HAD AN ATTORNEY and the attorney is still on the EAMS official address record as counsel of record, nobody will pay any attention to any of your letters.
