The New York Times has asked US District Judge Claude M. Hilton to dismiss a libel lawsuit brought by Dr. Stephen J. Hatfill, a former Army germ-warfare researcher who was named a "person of interest" by the FBI in its investigations of anthrax mailings shortly after the Sept. 11 attacks.

Hatfill sued the Times for libel and intentional infliction of emotional distress after the newspaper published a story stating that the government's decision not to further pursue Hatfill as a suspect was the result of "poor investigation." The newspaper moved to dismiss the lawsuit on the grounds that as a public speaker on bioterror, Hatfill is a public figure and therefore must prove a higher standard of defamation. The "public figure" must prove that the defamatory actions were taken with "actual malice", a standard which the Times motion contends Hatfill has failed to meet.

Hatfill's suit against the Times and columnist Nichols Kristoff was initially dismissed by a trial court, who ruled the columns were an ongoing report about a government investigation, not libel. The US Court of Appeals for the Fourth Circuit reversed, ruling that a jury should decide that issue. In March, the Supreme Court refused to grant certiorari in the case. Hatfill has also sued the government for related claims.
