On October 27, 2006, the American Civil Liberties Union (ACLU) withdrew their lawsuit challenging the constitutionality of the Patriot Act [PDF] after Congress amended the contested provision as part of the law's extension in 2006. The ACLU had argued that Section 215, which allowed federal agents to access personal information such as medical or library records without probable cause, violated Americans' constitutional rights. Congress amended Section 215 in March 2006 to allow persons faced with federal demands for information to seek legal counsel and bring a challenge in court. The Patriot Act, originally passed on October 26, 2001, was extended again in May 2011 for four additional years.
