WikiLeaks founder Julian Assange on Monday won the right to appeal his extradition to the United States. Assange’s lawyers argued before the British High Court that the U.S. government provided “blatantly inadequate” assurances that Assange would have the same free speech protections as an American citizen if extradited from Britain.

Assange has spent more than a decade facing the threat of extradition to the U.S., where he faces up to 175 years in prison for publishing classified documents exposing U.S. war crimes in Iraq and Afghanistan.

“This is a victory for Julian Assange in that he lives on to fight another day, his case lives on to fight another day. But he’s not out of Belmarsh [Prison] yet, and he’s not in the clear yet,” says Chip Gibbons, policy director of Defending Rights & Dissent. “This could still end in him being sent to the U.S. And the person who can stop this is Joe Biden and Merrick Garland.”
