What was John Roberts decision on the Affordable Care Act?

Chief Justice John Roberts played a pivotal role in upholding the Affordable Care Act (ACA) in 2012. He authored the majority opinion in National Federation of Independent Business v. Sebelius, ruling that the individual mandate, which requires individuals to purchase health insurance, was constitutional under Congress's taxing power. This decision was crucial in preserving the ACA, allowing it to remain in effect and expand access to healthcare for millions of Americans.
