After skipping bail in Britain, Assange spent seven years holed up in Ecuador’s embassy in London before he was dragged out by police in April last year.
The United States wants him extradited to face 18 charges including conspiring to hack government computers and violating an espionage law. He could spend decades in prison if convicted.
The 48-year-old Australian appeared for Monday’s hearing at Westminster Magistrates Court wearing glasses and a dark blazer over a light top. He spoke only to confirm his name and date of birth to the judge and saluted his supporters in the public gallery at the beginning and end of the hearing.
Assange’s lawyer Gareth Peirce said difficulty in getting time with Assange had delayed the case, telling the court: “This slippage in the timetable is extremely worrying.” Assange is being held in a British jail pending the U.S. extradition case, having served a sentence for skipping bail.
He fled to Ecuador’s embassy in 2012 to avoid being sent to Sweden to face sex crimes accusations that were dropped last year.
He says the U.S. charges against him are a political attempt to silence journalists and publishers, and that the Swedish allegations were part of a plot to catch him.
Assange made global headlines in early 2010 when WikiLeaks published a classified U.S. military video showing a 2007 attack by Apache helicopters in Baghdad that killed a dozen people, including two Reuters news staff.
Judge Vanessa Baraitser said Assange could have time on Monday to speak to his lawyers, and would appear in court again later on Monday.
Full extradition proceedings are expected to commence in February.
