The Expert Witness Grievance Process is a mechanism through which complaints can be lodged against STS members who may have violated the Society's standards for expert witnesses contained in the Statement on the Physician Acting as an Expert Witness . The Society's Procedural Guidelines for Handling Ethics Complaints Against STS Members  sets forth the process by which disciplinary action may be taken against a member who is alleged to have acted inappropriately in giving expert testimony, or otherwise acted unethically. The Guidelines were most recently amended by the STS Board of Directors in January 2011.
The Society established standards for expert witnesses in its Statement on the Physician Acting as an Expert Witness to promote fairness and accuracy in the field of medical liability. Initially adopted by the STS Board of Directors in May 2003, the Statement was adapted from guidelines developed by the Council of Medical Specialty Societies, the American College of Surgeons, and several other medical groups, and specifies standards for both the qualifications and behavior of physician expert witnesses. This policy, with which all STS members must comply, was most recently amended in June 2011.
