Calling the case a “brazen and outrageous fraud,” Facebook founder Mark Zuckerberg urged a federal court to dismiss a lawsuit by a New York man claiming he owns a huge stake in the multi-billion dollar social networking Web site.

In a filing yesterday with the US District Court in Buffalo, Facebook and Zuckerberg said the lawsuit by Paul Ceglia is based on a “doctored contract and fabricated evidence.” They also called the plaintiff “an inveterate scam artist whose misconduct extends across decades and borders.”
