A Case Study of U.S. Intelligence Agency Budget Transparency: Steven Aftergood vs National Reconnaissance Office (Li Jianren) With respect to the transparency of American government information, the law suit about intelligence agency is very sensitive and attractive. Steven Aftergood filed a law suit against National Reconnaissance Office (NRO) on June 30, 2005 for the defendant's refusing to disclose its Congressional Budget Justification Book (CBJB) for fiscal year 2006. According to several key clauses of Freedom of Information Act (FOIA) and Intelligence Authorization Act for Fiscal Year 2003 (IAA), the two major political parties debated intensely. During the law suit, senators and civil groups also participated in the debate, which showed that the law suit was a complex competitive game. The plaintiff finally won, but we can see, there are some regulations taking side on the intelligence agency, and these regulations are inconsistent with the spirit of FOIA. Moreover, these regulations have set up huge legal obstacles for American courts to protect the citizens- right to know.
