LONDON A British judge upheld an arrest warrant for Julian Assange on Tuesday, a significant setback for him after 5 1/2 years of evading the authorities by living in the Ecuadorean Embassy in London. Before the courtroom, Senior District Judge Emma Arbuthnot rejected the points made by Assange's lawyer, stating that he was not a prisoner, and in fact could walk free at any time to meet his legal fate, and that his living conditions were nothing like those of a prison.
