He originally camped on the grass in Parliament Square, but the Greater London Authority took legal action to remove him, so he relocated to the pavement, which was administered by Westminster City Council instead. In October 2002 Westminster City Council attempted to prosecute Haw for causing an obstruction to the pavement, but the case failed as Haw's banners did not impede movement. The continuous use of a megaphone by Haw led to objections by Members of Parliament who had offices close to Haw's protest camp. The House of Commons Procedure Committee held a brief inquiry in summer 2003 which heard evidence that permanent protests in Parliament Square could provide an opportunity for terrorists to disguise explosive devices, and resulted in a recommendation that the law be changed to prohibit them. The Government passed a provision banning all unlicensed protests, permanent or otherwise, in the Serious Organised Crime and Police Act 2005 (sections 132 to 138); however, because Haw's protest was on-going and residing on Parliament Square prior to the enactment of the Act, it was unclear whether the Act applied to him.
