Which court case overturned more previous decisions, Ableman v. Booth or Massachusetts v. Environmental Protection Agency?
Massachusetts v. Environmental Protection Agency Massachusetts v. Environmental Protection Agency, 549 U.S. 497 (2007), is a 5-4 U.S. Supreme Court case in which twelve states and several cities of the United States brought suit against the Environmental Protection Agency (EPA) to force that federal agency to regulate carbon dioxide and other greenhouse gases (GHGs) as pollutants.
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).
