This decision holds that under Evid. Code 721(b)(3), an expert may be cross-examined by a scientific or professional publication if the publication is established as a reliable authority by the cross-examined expert, another expert or judicial notice. Such a publication may be used even if the testifying expert did not consult it in preparing his opinion. Here, the testifying expert established that ASTM standards for paint on pavement were a reliable authority when he testified in his deposition that the ASTM standards are founded on good science and are well recognized and accepted in the scientific community. However, the trial court’s error in precluding cross-examination based on the ASTM standards was not prejudicial as they were not controlling and plaintiff had no evidence that she would not have fallen if the pavement paint had conformed to ASTM standards in all respects.
