In the United States v. Richardson case of 1973, the Supreme Court ruled that a taxpayer lacks standing to challenge the constitutionality of government spending, unless he can demonstrate direct injury or harm beyond his status as a taxpayer. The plaintiff, Richardson, argued that the CIA's undisclosed budget violated Article I Section 9 Clause 7 of the U.S Constitution which states "No Money shall be drawn from the Treasury but in Consequence of Appropriations made by Law; and a regular Statement and Account of Receipts and Expenditures of all public Money shall be published from time to time." However, due to lack of personal harm or injury caused by this alleged violation other than being a general taxpayer whose money contributes towards it indirectly - an issue shared with every other taxpaying citizen - Richardson was found not to have legal standing for his claim. This decision upheld previous rulings limiting taxpayers' rights to challenge federal expenditures.

In the dissenting opinion for United States et al. v. Richardson, Justice William O. Douglas argued that the plaintiff, as a taxpayer and citizen, had standing to challenge government activities related to CIA expenditures under Article I of the Constitution which requires an accounting of public money spent. He contended that secrecy in government is fundamentally anti-democratic and maintained that citizens have a right to know how their tax dollars are being used by agencies like the CIA - information necessary for informed voting and democratic governance. Furthermore, he asserted that if courts refuse taxpayers' rights to demand accountability from their government on spending matters due to lack of direct injury or personal stake beyond other taxpayers', then no one would be able check potential abuses of Congressional power over public funds; thus undermining constitutional checks and balances system.
