A federal judge in West Palm Beach, Fla., has rejected a request by the operator of the New York Stock Exchange that the names and home addresses of its European directors be removed from an Internet site operated by an animal rights group.

NYSE Euronext, created by the April combination of NYSE Group and Euronext N.V., argued that Bite Back and the Animal Liberation Front, two animal rights groups, were trying to force the closure of Princeton, N.J.-based Life Sciences Research and its subsidiary, Huntingdon Life Sciences, by harassing NYSE Euronext directors and threatening them with physical violence.
