NASCAR denied Friday that a former official, now suing for racial discrimination and sexual harassment, ever complained to her superiors about such problems.

The former employee often referred to herself with racial stereotypes and was repeatedly reprimanded for tardiness and other behavioral issues, NASCAR said. In addition, NASCAR said the firing of Mauricia Grant last October was legitimate and not an act of discrimination or retaliation.

The claims were part of a 29-page document filed Friday in response to Grant's $225 million lawsuit in the U.S. District Court for the Southern District of New York

A former technical inspector for NASCAR's second-tier Nationwide Series, Grant filed suit in June alleging 23 specific incidents of sexual harassment and 34 specific incidents of racial and gender discrimination over the two-plus years she worked for NASCAR.

Her suit alleges she was fired as retaliation for complaining to her superiors about the way she was treated by co-workers.

NASCAR chairman Brian France has maintained there is no record of Grant ever reporting anything, and the response filed by the New York-based law firm Jackson Lewis LLP is consistent with his claims.

The response claims Grant acknowledged an understanding of NASCAR's "zero tolerance policy against discrimination and harassment in the workplace," attended mandatory training seminars on the topics in 2006 and 2007 and acknowledged her obligation to immediately report any offensive acts in accordance with written policies.

A request to speak to Grant and her attorney, Benedict P. Morelli, wasn't immediately granted.

Grant has insisted she did complain, and followed the chain of command all the way to Nationwide Series director Joe Balash. But she stopped short of telling human resources, Grant said, because she was reprimanded by that department for a separate incident that occurred two weeks after she complained to Balash.

Grant said she viewed the reprimand, which included a threat of termination, as retaliation for complaining to Balash.

But in NASCAR's response, it claims Grant was reprimanded with a warning of termination for an altercation with a track security guard at Michigan International Speedway who had asked to see Grant's credentials as she passed through a gate.

The response does not indicate why Grant was fired, and NASCAR officials have refused to disclose the reason. But the response claims a pattern of tardiness that she was routinely reprimanded for. Continued...
