Abstract
The Anti-Injunction Act (“AIA”) is an important part of administrative procedure law and a crucial piece of the United States tax system. Enacted to help expedite the tax revenue process, the Act works to invalidate any lawsuit to restrict the assessment or collection of taxes. Nonetheless, having the power to bar standing and having the right to do so are two completely different things. For instance, while the AIA gives the power to bar suits brought against administrative rulemaking processes, the Act does not give this right unless the suit was brought with the purpose of restraining the assessment of a tax.
