The requesting state sought extradition of the defendant to face trial for electronically manipulating the Chicago Mercantile Exchange, which allegedly led the market to fall or climb to the value of $40 million. The defendant argued that crimes which he was accused of were not offences in the UK, and that if a trial was necessary, it was in the interests of justice for it to occur in this jurisdiction. He also argued that the extradition would infringe ECHR, art 8 and that the US request was an abuse of process, because it was premised on a materially misleading factual basis. Held: The extradition request was valid. Mark Summers QC and Aaron Watkins were involved in this case.
