Final answer:
Murphy v NCAA was a Supreme Court case that gave states the authority to decide whether or not to legalize sports betting. Before this case, the Professional and Amateur Sports Protection Act (PASPA) prohibited states from authorizing sports gambling. The Supreme Court ruled that PASPA violated the Tenth Amendment and overturned it.
Step-by-step explanation:
Murphy v NCAA was a landmark Supreme Court case that affected state governing of gambling. The case involved New Jersey's efforts to legalize sports betting. Prior to this case, the Professional and Amateur Sports Protection Act (PASPA) of 1992 prohibited states from authorizing or licensing sports gambling. However, in a 6-3 decision, the Supreme Court ruled that PASPA violated the Tenth Amendment of the United States Constitution, which protects state sovereignty. As a result, each state now has the authority to decide whether or not to legalize sports betting within its borders.
