Anti-terrorism, Crime and Security Act 2001

The Anti-Terrorism, Crime and Security Act 2001 was formally introduced into the Parliament of the United Kingdom on 19 November 2001 two months after the September 11, 2001 attacks on New York. A Parliamentary committee was critical of the swift timetable for such a long Bill.[1] It received royal assent and went into force on 13 December 2001. Many of its measures were not related to terrorism.

On 16 December 2004 the Law Lords ruled that Part 4 was incompatible with the European Convention on Human Rights, but under the terms of the Human Rights Act 1998 it remained in force.
