The order came a little more than a month after the Supreme Court of the United Kingdom refused to hear Assange's appeal. In December, the UK High Court of Justice granted the US government's appeal and overturned a district court decision that spared Assange.

Chief Magistrate Senior District Judge Paul Goldspring contended he was "duty-bound" to send the extradition request to Patel. Goldspring also told Assange he had a right to appeal if the Home Office approved the extradition before issuing the order.

Mark Summers QC, an attorney for Assange, asserted there were "fresh developments" in the case and bemoaned the fact that the defense was not permitted at this stage to raise this evidence, according to Computer Weekly's Bill Goodwin.

Assange's legal team has until May 18 to submit evidence to the Home Office and argue why the department should block the extradition request. In two months, Patel is expected to make a decision.

If approved by Patel, attorneys for Assange may request permission to appeal to the British High Court of Justice. His attorneys may appeal the decision of the district judge to send the case to the Home Office for approval and may also appeal the Home Office secretary's order.
