Expert witness play a very important role in medical malpractice cases. You cannot get to a jury or past a judge’s directed verdict without expert witnesses supporting your case. They must review the case, be of the same or similar specialty of the doctor you’re bringing an action against, and render an opinion that that doctor, more likely than not, caused or contributed to the cause loss, injury or damage to your loved one by breaching the standard of care, that is doing something a reasonable physician wouldn’t do, or not doing something that a reasonable physician would do or should do.
