The Joint Committee on Human Rights says that Terrorism Prevention and Investigation Measures (TPIMs) may be withering on the vine as a counter-terrorism tool of practical utility and concludes that in 2015 the new Government must urgently address the role and effectiveness of these measures within the context of a broader review of counter-terrorism powers. As of 30 November 2013 there were 8 TPIM notices in force, all of which were in respect of British citizens. TPIM subjects are subject to restrictions including overnight residence at a specified address, GPS tagging, reporting requirements and restrictions on travel, movement, association, communication, finances, work and study. Most of the current TPIMs are due to expire shortly, but the Committee believes that Parliament was right to impose a two year limit on their duration: such serious restrictions on liberty, imposed outside of the criminal justice system, cannot be indefinite. The Committee calls on the Government to put more information into the public domain about the types of work it has carried out with TPIMs subjects with a view to minimising any risk of terrorism-related activity when their TPIMs expire, including a fuller explanation of how that work relates to its other work on de-radicalisation .
