Mayfield asks judge to reconsider dismissal

In his latest court filings, Jeremy Mayfield claims that NASCAR's problems with him started well before he was indefinitely suspended in 2009 because of a positive drug test.

Mayfield is asking U.S. District Court Judge Graham Mullen to reconsider a 2010 ruling that dismissed his lawsuit against NASCAR regarding the drug test that NASCAR says was positive for methamphetamine.

In claims filed this week, Mayfield says NASCAR Chairman Brian France had him black-flagged during the 2006 Brickyard 400 at Indianapolis Motor Speedway and NASCAR officials were upset with him in 2009 for signing a sponsor they were wooing, SceneDaily.com reports.

Mayfield wants to amend his initial lawsuit to include those new claims, SceneDaily.com reports, saying that NASCAR illegally interfered with his team business affairs. He also claims France's personal malice against him influenced those business actions.

NASCAR spokesman Ramsey Poston denies the new and old allegations.

"Mayfield's claims are blatantly false and Jeremy and his lawyers know it," Poston said in a statement. "In fact, prior to their filing we notified Mayfield's lawyers that the allegations were completely baseless and that we had evidence to prove the falsity of the claims.

"Mayfield and his lawyers chose to continue a campaign of lies and disregard the evidence that was discussed with them."

Mayfield has denied using methamphetamine. He says the positive drug test resulted from a combination of the prescription drug Adderall and over-the-counter allergy medication.
