US man demands half of Facebook

A US man who is continuing with a legal claim for half-ownership of Facebook will not be able to question the firm's founder, Mark Zuckerberg, at this stage in the lawsuit, a judge has ruled.

Paul Ceglia says he gave Mr Zuckerberg $1,000 (£629) in 2003 to help set up Facebook and that a deal was signed.

Facebook says the document is a fake and wants the case to be dismissed.

Mr Ceglia's lawyers have been asked to submit expert reports on the contract within two months.

Magistrate Judge Leslie Foschio also said that Mr Ceglia's lawyers would be able to question Facebook's own experts about the two-page document.

While Mr Ceglia, of Buffalo, New York, says the contract entitles him to half-ownership of Facebook, Mr Zuckerberg counters that he had not conceived of the social network at the time.
