The Supreme Court was tasked with one of its most-watched cases in history in 2012, when President Obama's healthcare law was brought before the court.
FOX News Radio's Jared Halpern followed the landmark case through the court and takes a look back:
Even before arguments were made, legal analysts like Betsy Goldman with Bloomberg Law were predicting a historic affair.
(Goldman) "This is up there with Brown v. Board, this is up there with Bush v. Gore."
For three days the last week of March, the nine justices heard six hours of oral arguments - an amount of time rarely afforded. The focus was the individual mandate, the requirement to purchase health insurance or pay a fine.
(Verrilli) "Under the Commerce Clause, what Congress has done is to enact reforms of the insurance market."
Solicitor General Donald Verrilli arguing the individual mandate is necessary to bring down the cost of healthcare. Paul Clement, who argued the case for healthcare law opponents, told the court the Commerce Clause only gives Congress over existing commerce.
(Clement) "It does not give Congress the far greater power to compel people to enter commerce, to create commerce, essentially, in the first place."
The majority of justices agreed the Commerce Clause does not allow Congress to make you buy anything. Instead, Chief Justice John Roberts, in a rare opinion signed on by no other justice, upheld the individual mandate through Congress's taxing authority, writing "Congress has increased taxes on those who have a certain amount of income, but choose to go without health insurance."
While the opinion left open the possibility of repeal, November's elections all but sealed the fate of the controversial law.
