WikiLeaks founder Julian Assange appeared in a U.K. court Monday to fight extradition to the United States on espionage charges, and he lost a bid to delay proceedings so that his legal team would have more time to prepare his case.

Assange defiantly raised a fist to supporters who jammed the public gallery in Westminster Magistrates Court for a rare view of their hero. He appears to have lost weight but looked healthy, although he spoke very softly and at times seemed despondent and confused.

Assange and his legal team failed to convince District Judge Vanessa Baraitser that a delay in the already slow-moving case was justified. The full extradition is still set for a five-day hearing in late February, with brief interim hearings in November and December.

Assange hadn’t been seen in public for several months and his supporters had raised concerns about his well-being. He wore a blue sweater and a blue sports suit for the hearing, and had his silvery-gray hair slicked back.

After the judge turned down his bid for a three-month delay, Assange said in halting tones he didn’t understand the events in court.

He said the case is not “equitable” because the U.S. government has “unlimited resources” while he doesn’t have easy access to his lawyers or to documents needed to prepare his battle against extradition while he is confined to Belmarsh Prison on the outskirts of London.

U.S. authorities accuse Assange of scheming with former Army intelligence analyst Chelsea Manning to break a password for a classified government computer.

Lawyer Mark Summers, representing Assange, told the judge that more time was needed to prepare Assange’s defense because the case has many facets, including the very rare use of espionage charges against a journalist, and will require a “mammoth” amount of planning and preparation

“Our case will be that this is a political attempt to signal to journalists the consequences of publishing information. It is legally unprecedented,” he said.

He also accused the U.S. of illegally spying on Assange while he was inside the Ecuadorian Embassy seeking refuge and taking other illegal actions against the WikiLeaks founder.
