Policy background Monitoring and prevention
The TPIM Act 2011 replaced the previous system of control orders. It provides for a number of measures to be imposed on individuals who the Home Secretary believes have, on "the balance of probabilities" (as amended by the Counter-Terrorism and Security Act 2015), been involved in terrorism related activity. The Counter-Terrorism and Security Act 2015 made some amendments to the TPIM Act 2011. These amendments followed recommendations that the former Independent Reviewer of Terrorism Legislation (IRTL), David Anderson QC, made in his annual report. These amendments addressed the changing threat picture in 2015. More recently, in response to the Streatham attack, Lord Carlile QC, another former IRTL, called for tougher restrictions on released prisoners, such as the reintroduction of control orders. The Government does not consider it necessary to reintroduce control orders; sufficient amendments can be made to the TPIM Act 2011 to strengthen it. These amendments include: lowering the standard of proof for imposing a TPIM to "reasonable belief"; extending the maximum duration of a TPIM notice from two years to five; and allowing for a flexible curfew rather than the current overnight measure.
	In his 2019 report, Jonathan Hall QC, the Independent Reviewer of Terrorism Legislation found that "The power of the High Court to make SCPOs is a seriously underused power generally, and has not been used in connection with suspected terrorists to date". The changes in this legislation are intended to help support the use of SCPOs in terrorism cases by simplifying the process for police to make an application for an SCPO.
	The 2008 Act provides a notification regime for individuals sentenced to 12 months’ or more imprisonment for a specified terrorism offence or (in England, Wales and Scotland) an offence with a terrorism connection. This notification regime was strengthened by the 2019 Act to require Registered Terrorist Offenders to provide additional information to the police. This legislation will add further offences to those leading to notification requirements for individuals convicted of terrorism or terrorism-related offences on their release from prison.
