Check out the New York Times article about the so called "independent medical exam". Ohio has just as big a problem as New York and judges need to prohibit these doctors from testifying. If they were held in contempt for perjury it would send a stong message to the insurance industry that pays for these opinions. All the injured victim wants is a level playing field and permitting the defense doctors to falsely testify is just wrong.
