Cal: Its a statute that requires ALL auto personal injury claimants who have elected that threshold on their policy (which 90% have) to have a " permanent " and "siginifcant" injury resulting in the loss of a body function which MUST be supported by OBJECTIVE CLINICAL MEDICAL EVIDENCE. A treating doctor or a doctor to whom the person was refered by the treating doctor MUST sign an affitdavit saying such an injury exists and the medical basis for the fact such injury exists or the case is tossed.
