The Supreme Court of London has ruled that US guarantees in the case of WikiLeaks founder Julian Assange are unsatisfactory and he will be entitled to a full hearing on the appeal, reports "Reuters".
In March, the Supreme Court granted Assange, 52, temporary permission to appeal on three grounds. But it did allow the US to provide satisfactory assurances that it would not seek the death penalty and allow him to invoke his First Amendment right and protection of free speech at trial.
In a brief ruling, two senior judges said the U.S. submissions were insufficient and said they would allow the appeal to continue.
Assange-founded WikiLeaks released hundreds of thousands of classified US military documents about Washington's wars in Afghanistan and Iraq - the biggest security breaches of their kind in the history of the US military - along with scores of diplomatic cables.
In April 2010, Wikileaks released classified video showing a 2007 US helicopter attack that killed a dozen people in the Iraqi capital Baghdad, including two Reuters staff.
US authorities want to put Assange on trial on 18 charges, almost all under the Espionage Act, saying his actions with WikiLeaks were reckless, damaged national security and endangered the lives of agents.
His many global supporters call the prosecution a travesty and an assault on journalism and freedom of speech. Calls for an end to the case have come from human rights groups, media outlets and Australian Prime Minister Anthony Albanese, along with other political leaders.
Assange was first arrested in Britain in 2010 on a Swedish warrant on sex offense charges that were later dropped.
The Australian computer expert has spent the past five years in Britain's high-security Belmarsh prison after taking refuge in the Ecuadorian embassy in London for seven years.
President Joe Biden said in April he was considering asking Australia to drop a decade-long US push to prosecute the Wikileaks founder.
