WEST MILFORD The lawsuit filed by Councilman James Warden and resident Bettina Biere now names Former Councilman Joseph Elcavage as one of the defendants. The suit, filed earlier this year, alleges slander and libel on a now-defunct Web site and a community bulletin board site. Warden has claimed from the beginning that the statements in question, although very personal in nature, were politically motivated. He and Biere filed suit against mostly John Does and pseudonyms under which people had posted. His lawyer, who is also his brother, Jeff Warden, then started an investigation to identify the anonymous writers. The lawsuit, which seeks unspecified damages and asks for a trial by jury, now includes Tom Malone, former councilman Denis Kirwan, former board of education trustee Ken Freedman (who ran unsuccessfully against Warden for a council seat) and now former councilman Elcavage. Warden said he expected one more politically connected name to be revealed by the end of the investigation.
