Assange appeals extradition at the Supreme Court WikiLeaks founder Julian Assange is appealing his extradition to Sweden to face sex crime charges at Britain's Supreme Court. Assange was detained in the UK in December 2010 on a European arrest warrant issued by a Swedish prosecutor after two female former WikiLeaks volunteers accused him of sexual assault. The Australian born Assange rejects the charges and claims the sex accusations, which surfaced at the same time as WikiLeaks published secret US diplomatic communications on the wars in Iraq and Afghanistan, were trumped up to silence him. WikiLeaks has since faded from the news and is struggling for money as major credit card companies are refusing to process donations to it. Assange has been under house arrest for over a year. The Supreme Court hearing will last two days, it's decision will be announced in some weeks.
