A control order is an order made by the Home Secretary of the United Kingdom to restrict an individual''s liberty for the purpose of "protecting members of the public from a risk of terrorism". Its definition and power were provided by Parliament in the Prevention of Terrorism Act 2005. Control orders were also included in the Australian Anti-Terrorism Act 2005. The control orders section of the Prevention of Terrorism Act provides for extremely limited rights of appeal and the absence of double jeopardy restrictions (i.e if a recipient managed to win an appeal in the Court of Appeal or other tribunal - the home office could simply re-apply the same order again). This has led to many court rulings highly critical of the orders.
