of detention conferred by Part 4 of ATCSA were incompatible with the UK's obligations under the European Convention on Human Rights. The Court ruled by a majority of 8–1 that the purported derogation was not authorised by Article 15 of the European Convention on Human Rights since the measures taken could not rationally be held to be "strictly required by the exigencies of the situation", and were also discriminatory contrary to Article 14 of the Convention. The ruling could be summed up as follows: No detention pending deportation had lasted for more than seven days, let alone three years. The law was unjustifiably discriminatory. What if a British citizen was also suspected of terrorism which required that they be detained indefinitely without trial? There was no way to do it. There was no observable state of emergency threatening the life of the nation. No other European country which had experienced far more severe crises had declared such a state of emergency over such a long time period, and certainly without anyone noticing. The Court quashed the order derogating from the UK's obligations under the Convention, and issued a declaration pursuant to section 4 of the Human Rights Act 1998 that the provisions of the ATCSA which empowered the preventative detention of non-British suspected international terrorists were incompatible with the European Convention. The effect of such a declaration in British law is not to deprive the legislation of legal effect, and Parliament may, if it wishes, refuse to repeal or amend any provision declared to be incompatible. However the making of a declaration of incompatibility carries strong moral force, and creates considerable political pressure to address the incompatibility. Replacement of Part 4 To this end Part 4 of the ATCSA was replaced by the Prevention of Terrorism Act 2005 in March 2005. This Act replaces detention in prison with "control orders" which allow for the imposition of an extensive and non-exhaustive set of conditions on the movements of the suspected person with restrictions approaching a form of house arrest. Unlike Part 4 of the ATCSA, the powers in the Prevention of Terrorism Act 2005 can be applied to British and non-British suspected terrorists alike. At the time of its enactment there was considerable debate as to the compatibility of this Act's provisions with domestic and international human rights laws. Eleven control orders were issued on the night the act passed on
