In the 1984 ruling of "South Carolina v. Regan", Justice William Brennan delivered the Supreme Court's opinion detailing that the Anti-Injunction Act could not be used to prevent a legal suit if there did not exist a judicial process through which a plaintiff could make their case. This occurred due to the state of South Carolina lacking a direct method of challenging the removal of bearer bonds. The ruling therefore expanded on the instances in which the Anti-Injunction Act was not applicable, beyond the two exceptions set out by "Bob Jones Univ. v. Simon" and the earlier court case "Enochs v. Williams Packing Co.", and thus partially overruling "Bob Jones Univ. v. Simon" with the modifications to the use of the Anti-Injunction Act concerning future suits.
