Which court case overturned more previous decisions, Ableman v. Booth or Massachusetts v. Environmental Protection Agency?
Ableman v. Booth Ableman v. Booth, 62 U.S. 506 (1859) , was a United States Supreme Court case in which the Court held that State courts cannot issue rulings on federal law that contradict the decisions of federal courts, overturning a decision by the Supreme Court of Wisconsin. The Supreme Court held that under the Constitution, the federal courts have the final power to decide cases arising under the Constitution and federal statutes, and that the States do not have the power to overturn those decisions. Thus, Wisconsin did not have the authority to nullify federal judgments or statutes.
Poe v. Ullman Poe v. Ullman, 367 U.S. 497 (1961) , was a United States Supreme Court case that held that plaintiffs lacked standing to challenge a Connecticut law that banned the use of contraceptives, and banned doctors from advising their use, because the law had never been enforced. Therefore, any challenge to the law was deemed unripe, because there was no actual threat of injury to anyone who disobeyed the law. The same statute would later be challenged yet again (successfully) in "Griswold v. Connecticut" (1965).
