CHARLOTTE, N.C. (AP) - NASCAR has filed a motion in federal court that says an expert witness for suspended driver Jeremy Mayfield lied about his credentials.
The motion was filed Tuesday. It claims Dr. Harvey MacFenerstein falsely represented himself on six counts in a May 29 affidavit presented on behalf of Mayfield, who was suspended indefinitely by NASCAR after failing a drug test.
NASCAR says MacFenerstein does not have the medical degrees or certifications he listed in his qualifications.
In his testimony about NASCAR's drug-testing policy, MacFenerstein said the policy is flawed and does not meet federal workplace guidelines. His findings were the basis of Mayfield's argument that he should be immediately reinstated.
