The Seventh Circuit opinion in Austin v. AANS, with its embrace of the value of peer review of expert testimony, may well stimulate other professional groups in medicine, mental health, and other fields to become involved in such activities. As desirable as this may be, it will not absolve the courts of their responsibility to determine the validity of proposed expert testimony at the time of trial; peer review, after all, is inherently retrospective. But whether by imposing sanctions or by providing educational feedback, over time professional associations can elevate the level of expert guidance that our courts receive. The Austin case demonstrated that as long as this task is performed in good faith and with respect for the rights of the accused member, it is likely to be upheld by the courts and insulated from the threat of subsequent liability.
