Ehrenfeld became involved in an international legal controversy when she lost a libel case brought before Mr Justice David Eady in the English High Court of Justice by Saudi businessman Khalid bin Mahfouz concerning her book Funding Evil. She preemptively counter-sued bin Mahfouz to obtain a declaration that the judgment would not be enforced in the United States and that her book was not defamatory under United States defamation law, but her lawsuit was dismissed by the New York courts on the grounds of a lack of personal jurisdiction over bin Mahfouz.

Paterson signed, a law which "offers New Yorkers greater protection against libel judgments in countries whose laws are inconsistent with the freedom of speech granted by the United States Constitution."
