Among other provisions Part 2 of the Act: Extradition to category 2 territories (non-European Arrest Warrant territories) removed the requirement on the US to provide "prima facie" evidence in extraditions from the UK, requiring instead only "reasonable suspicion". This was necessary to redress the previous imbalance against the US under the 1870 Act, as the UK did not have to provide the more onerous "prima facie" evidence to extradite from the US. The requirement for the UK is to show "probable cause". However, an independent legal review carried out by Sir Scott Baker found that "there is no significant difference between the probable cause test and the reasonable suspicion test. There is no practical difference between the information submitted to and from the United States."
