> who rendered a detailed decision based on significant amounts of witness testimony

This is factually incorrect. The UK High Court ruled only on the question of whether the European Arrest Warrant was valid. It did not consider the reasonableness of the allegations and dismissed defense attempts to challenge them on empirical grounds:

> "[Assange's objections] are matters which would be highly relevant at trial. But it is not for this court to determine whether the allegations may fail." (126)
