13.Part II is based on Part I of the PTA (which has effect in Great Britain only) and on sections 30–31 of the EPA (which have effect in Northern Ireland only). The proscription regime under the Act differs from those it replaces as follows:
	The PTA and EPA provide separate proscription regimes for Great Britain and Northern Ireland. Under the Act proscription will no longer be specific to Northern Ireland or Great Britain, but will apply throughout the whole of the UK.
	Under the PTA and EPA proscription is only applicable to organisations concerned in Irish terrorism. Under the Act it will also be possible to proscribe organisations concerned in international or domestic terrorism.
	Under the PTA and EPA an organisation or an affected individual wishing to challenge a proscription can only do so in the UK via judicial review (no proscribed organisation has ever done this). Under the Act, organisations and individuals will be able to apply to the Secretary of State for deproscription and, if their application is refused, to appeal to the Proscribed Organisations Appeal Commission (“POAC”; see below).
