Have you read the previous articles about the Assange hearing? That will probably provide the context you're missing. The short answer as far as I have understood is that the Assange's defense is arguing that he can't be extradited to the US because the extradition treaty between the US/UK forbids extradition for "political offences." The prosecution is arguing that the treaty is not actually law, and that the UK's domestic laws on extradition do not forbid extradition for "political offences."
