The International League against Racism and Anti-Semitism (LICRA), which in February called for a boycott of Yahoo! sites for the same reason, said it was seeking an injunction in a Paris court to force the Santa Clara, California-based company to stop the sales in France.
"LICRA demands that Yahoo take the necessary measures to prevent the exhibition and sale on its sites of Nazi objects throughout the national territory," the group said in a statement.
A spokesman for Yahoo! declined to comment on the matter. Judicial sources said a hearing was set for May 15. LICRA said it would ask the judge to order Yahoo! to pay a daily fine of 100,000 euros (US$95,880) until it complies with the injunction.
A Yahoo.com auction site puts hundreds of Nazi or neo-Nazi, or Ku Klux Klan objects up for auction each day, including films, swastikas, uniforms, daggers, photos and medals.
Under French law, it is illegal to exhibit or sell objects with racist overtones.
"This sale of symbols of the greatest-ever crime against humanity trivializes Nazism in the extreme," LICRA said.
LICRA did not say how access to a Web site could be blocked in France only.
Yahoo! came under fire in February from another anti-racism group, the Anti-Defamation League, which accused the Web service provider of hosting dozens of sites that promoted messages from racist hate groups including neo-Nazis and the Ku Klux Klan.
