Terrorism Prevention and Investigation Measures Act 2011

This note examines the changes to the control order regime brought about by the introduction of Terrorism Prevention and Investigation Measures under the Terrorism Prevention and Investigation Measures Act 2011. It considers the operation of the Act during its first two years, including its effectiveness, criticisms and proposals for change.

TPIMs aim to disrupt terrorism related activity, and to facilitate the investigation of such activity, amongst those suspected of involvement, but who it is not possible to prosecute. The TPIMA sought to liberalise the control order regime, introduced by the previous Government under the Prevention of Terrorism Act 2005, by removing the most restrictive aspects of control orders and imposing a higher threshold for the imposition of TPIMs, and a finite limit of two years.
