Terrorism Acts

From Wikipedia, the free encyclopedia

From 2000 to the 2015, the British Parliament passed a series of Terrorism Acts that were aimed at terrorism in general, rather than specifically focused on terrorism related to Northern Ireland. The timings were influenced by the September 11, 2001 attacks and 7 July London bombings, as well as the politics of the Global War on Terrorism, according to the politicians who announce them as their response to a terrorism act.[citation needed]

Between them, they provided a definition of terrorism that made it possible to establish a new and distinct set of police powers and procedures, beyond those related to ordinary crime, which could be applied in terrorist cases.

List of legislation[edit]

The Terrorism Act 2000 (text)
  • gave a broad definition of terrorism for the first time

In February 2009, the Liberal Democrats published a Freedom Bill designed to repeal many of these laws (as well as others such as the Identity Cards Act 2006) aimed at reversing the "cumulative loss" of civil liberties in Britain.[10]

In his comprehensive commentary on the anti-terrorism legislation, Professor Clive Walker of the University of Leeds comments:

The Terrorism Act 2000 represents a worthwhile attempt to fulfil the role of a modern code against terrorism, though it fails to meet the desired standards in all respects. There are aspects where rights are probably breached, and its mechanisms to ensure democratic accountability and constitutionalism are even more deficient, as discussed in the section on "Scrutiny" earlier in this chapter. It is also a sobering thought, proffered by the Home Affairs Committee, that the result is that "This country has more anti-terrorist legislation on its statute books than almost any other developed democracy." (Report on the Anti-terrorism, Crime and Security Bill 2001 (2001-02 HC 351) para.1). But at least that result initially flowed from a solemnly studied and carefully constructed legislative exercise.[11]

Since the 1970s, an Independent Reviewer of Terrorism Legislation has reviewed the operation of the UK's principal anti-terrorism laws, reporting to the Home Secretary and to Parliament.
