Prior to the United Kingdom's exit from the European Union, a limited number of territories were referred to as Category 1 territories. But, with Britain's leave, all European nations, including Gibraltar, are now classified as category 1 territories.
In terms of the contrast between categories 1 and 2, category 1 territories are those that deal with extradition formalities under Part 1 of the Extradition Act (2003). Any extradition agreements made between the United Kingdom and the European Union after December 31, 2020, will be based on existing conditions.
Part 2 of the Extradition Act governs extradition judicial processes in Category 2 territories (2003). Several nations have separate and different treaties with the UK, which are founded on mutual interests. Category 2 areas are further subdivided into A and B.
Category A individuals are exempt from providing obvious and first-impression evidence in support of their extradition request. Category B nations, on the other hand, are required to bring such proof.
