LAS VEGAS — Nevada Gov. Jim Gibbons was sued in federal court on Tuesday by a woman who had claimed he assaulted her after they and others had drinks just before the November 2006 elections.

The lawsuit filed by a lawyer for Chrissy Mazzeo two years and a day after the alleged incident names Gibbons, longtime political operative Sig Rogich and Pennie Mossett-Puhek, who were with Gibbons and Mazzeo at a popular Las Vegas restaurant the night of the alleged incident.

Also named were the Las Vegas Metropolitan Police Department, former Metro Police Chief Bill Young, and Don Campbell, the attorney who represented Gibbons when the allegations were first raised.

The suit, filed in U.S. District Court by Las Vegas attorney Robert Kossack, alleges, among other things, that the defendants slandered Mazzeo and conspired to obstruct justice in the case. It seeks unspecified general, special and punitive damages.

Gibbons spokesman Ben Kieckhefer said he didn’t have any immediate comment on the lawsuit. He said he was trying to get in touch with legal counsel for the governor to “coordinate a response.” Until that’s done, Kieckhefer said he didn’t want to speculate or say something “that is out of the bounds of what’s proper.”

The first-term Republican governor, in Washington, D.C., for meetings with Interior Department officials, had previously denied any wrongdoing.

Mazzeo, 34, who worked as a cocktail waitress in Las Vegas and has since moved to Southern California, alleged at the time that Gibbons pushed her against a wall in a parking garage and propositioned her for sex outside the restaurant. Gibbons said he helped Mazzeo remain on her feet after she slipped.

Authorities who investigated the case decided against filing criminal charges, citing insufficient evidence.
