National Federation of Independent Business v. Sebelius

The National Federation of Independent Business v. Sebelius (2012) was a Supreme Court case about the Affordable Care Act (Obamacare). The main issues were whether the law's requirement for individuals to buy health insurance (individual mandate) and expand Medicaid was constitutional. The Court ruled that the individual mandate could be seen as a tax and thus was within Congress's powers, but the Medicaid expansion exceeded federal authority and was therefore invalid. This decision upheld most of the law but limited the federal government's power to enforce Medicaid expansion, balancing federal and state powers.
