NEW YORK Aug 10 (Reuters) - While civil suits have wider latitude of what may be introduced in court, a judge in the Dominique Strauss-Kahn civil case will want hard evidence rather than mere accusations from other women that he sexually assaulted them, analysts say.

In a lawsuit filed this week, Nafissatou Diallo accused Strauss Kahn, 62, of waging a "violent and sadistic" attack on her in a suite at the Sofitel hotel in Manhattan on May 14.

Strauss-Kahn has also been charged with sexual assault in criminal court and prosecutors are debating whether to move forward with that case despite concerns about Diallo's credibility.

No date has yet been set for the civil case, but Diallo's lawyer has said she will introduce evidence from women who allegedly were sexually assaulted by the former International Monetary Fund chief in apartments and hotel rooms around the world as well as co-workers whom he is alleged to have sexually coerced.

The stakes are lower in the civil case -- monetary damages, rather than prison time -- but analysts said the admissibility standard remains a high hurdle.

"It's very restrictive for obvious reasons, because otherwise you could just march in a bunch of people who say, 'This is a terrible guy,'" said David Golomb, a former president of the New York State Trial Lawyers Association.

Defense attorney Oscar Michelen agreed that Diallo will have a tough time convincing a judge to admit allegations that Strauss-Kahn, a French citizen, has assaulted or coerced women in the past.
