In her ruling last week, U.S. District Judge Colleen Kollar-Kotelly said Paul David Gaubatz must return documents to the Council on American-Islamic Relations, McClatchy Newspapers reported. The documents were allegedly stolen by Gaubatz's son.
Gaubatz is a former Air Force officer who calls himself an anti-terrorism investigator. "Muslim Mafia: Inside the Secret Underworld That's Seeking to Islamize America," written with Paul Sperry, charges CAIR is riddled with terrorist agents and is a subversive group.
"The record ... supports a finding that defendants have unlawfully obtained access to, and have already caused repeated public disclosure of, material containing CAIR's proprietary, confidential and privileged information," the judge said.
Gaubatz, in an e-mail Monday, said he had expected the lawsuit.
"Intimidations, threats and lawsuits are CAIR's basic tactics," Gaubatz said.
The book includes a forward by Rep. Sue Myrick, R-N.C., who says Gaubatz is a "great American."
