( Mashable ) -- Cameron and Tyler Winklevoss must accept their $ 65 million settlement from Facebook and move on . A U.S. appeals court ruled Monday that the settlement -- which was featured in the movie `` The Social Network '' -- still stands , despite the Winklevosses ' claim that Facebook did not disclose an accurate valuation . The suit stems from the Winklevosses ' claim that Facebook co-founder and CEO Mark Zuckerberg stole their idea for the social-networking site . Zuckerberg and Facebook deny the allegations , but agreed to settle in 2008 . Since then , the Winklevoss twins have attempted to secure a higher settlement by claiming that Facebook is guilty of securities fraud . `` The Winklevosses are not the first parties bested by a competitor who then seek to gain through litigation what they were unable to achieve in the marketplace , '' Chief Judge Alex Kozinski wrote in today 's ruling . `` And the courts might have obliged , had the Winklevosses not settled their dispute and signed a release of all claims against Facebook . '' With both the district court and appeals court in agreement , it seems this may be the end of the Winklevosses ' claim to any additional shares of Facebook . `` For whatever reason , they ( the Winklevosses ) now want to back out . Like the district court , we see no basis for allowing them to do so , '' Kozinski wrote . `` At some point , litigation must come to an end . That point has now been reached .
