The Terrorism Prevention and Investigation Measures Act 2011 (c.23) (“the Act”) provides the Secretary of State with the power to impose terrorism prevention and investigation measures on an individual where the conditions in section 3 of the Act are met. Such measures are imposed by means of a “TPIM notice”. In addition to the power to impose a TPIM notice, the Secretary of State has powers to extend and vary a TPIM notice that is in force and power to revive a TPIM notice that has expired. Section 21(1) of the Act provides that the Secretary of State’s TPIM powers are to expire at the end of the period of five years beginning on the date the Act was passed. However, section 21(2)(c) contains a power for the Secretary of State, exercisable by order, to provide that those powers will not expire in accordance with subsection (1) but may continue for a period of up to five years. This Order provides that the Secretary of State’s TPIM powers will continue in force for a further five years.
