The British catwalker tried to block former maid Gaby Gibson from bringing up Campbell's history of dust-ups with people who work for her, saying it was "scandalous and prejudicial." But in a ruling published Wednesday, Manhattan state Supreme Court Judge Michael Stallman said previous incidents could be admitted.
"Those alleged acts might be relevant to the issues of intent and the need for future deterrence," Stallman wrote.
Gibson was "very happy" about Stallman's ruling, said her lawyer, Lambros Lambrou.
Gibson worked for Campbell from November 2005 through January 2006. She claims the 37-year-old model hit her, called her bigoted names and threatened to charge her with theft after being unable to find a pair of jeans designed by Stella McCartney.
Campbell has denied the claims. She was never charged with any crime in the incident Gibson alleges.
Campbell did plead guilty in January to misdemeanor assault for throwing her cell phone at another maid, Ana Scolavino. Sentenced to pay Scolavino's medical expenses, attend an anger management program and do five days of community service, Campbell traded couture togs for a city Department of Sanitation vest to sweep, mop and scrub at a Manhattan garbage truck garage in March.
Campbell also has faced other lawsuits from other former employees who accused her of violent behavior. She settled a claim filed by former employee Amanda Brack this year, but no settlement terms were disclosed.
