The original case began with Yahoo!'s listing of Nazi memorabilia, which is a prohibited item in France, on its website in France. A complaint was filed by the Union of Jewish Students in France (UEJF) and the League Against Racism and Anti-Semitism (LICRA) against Yahoo!
The French court ruled that Yahoo! could be fined $15 million unless the items were inaccessible to French residents; Yahoo! decided to remove the items altogether.
One of the issues now is whether Yahoo! can countersue UEJF and LICRA, which is why UEJF and LICRA took the case to the Supreme Court, but morevover it opens the door to whether defendants in lawsuits that cross national boundaries can file countersuits in their home jurisdictions.
