During a parliamentary debate on the Terrorism Bill in 2000, MPs asked whether the legislation could be used to proscribe Greenpeace as a terrorist organisation. The group had, in recent years, temporarily blocked nuclear warhead production at AWE Aldermaston, spray-painted a power station and destroyed a field of genetically modified maize. The home secretary, Jack Straw, replied that he ‘knew of no evidence whatever that Greenpeace is involved in any activity that would fall remotely under the scope of this measure’. Proscription was a ‘heavy power’ that would be used only when ‘absolutely necessary’, he said, and the Human Rights Act 1998 was a ‘profound safeguard’ against its disproportionate use.
