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 NASCARs drug-testing policy, MacFenerstein said the policy is flawed and does not meet federal workplace guidelines. His findings were the basis of Mayfields argument that he should be immediately reinstated.
