Twin brothers who accused Facebook Inc and its founder Mark Zuckerberg of stealing their idea for the social networking website lost their bid to have a federal appeals court void a settlement of their claims.
Cameron and Tyler Winklevoss, who were classmates of Zuckerberg at Harvard University, had sought to reopen the cash-and-stock settlement, which has been valued at $65 million.
The 9th US circuit court of appeals in San Francisco had on April 11 refused to change that accord.
That court on Monday rejected the twins' request to have an 11-judge panel review its earlier ruling. It did not provide a reason.
A lawyer for the Winklevosses did not immediately return a call seeking comment.
