Roberts was less clear on whether that also meant the rest of the law must fall, the source said. The other four conservatives believed that the mandate could not be lopped off from the rest of the law and that, since one key part was unconstitutional, the entire law must be struck down.Crawford acknowledges that her sources do not know exactly why he switched. His critics say that he buckled to pressure while supporters say that he reasoned on the merits. Here is what Roberts himself wrote:
Because Roberts was the most senior justice in the majority to strike down the mandate, he got to choose which justice would write the court's historic decision. He kept it for himself.
Over the next six weeks, as Roberts began to craft the decision striking down the mandate, the external pressure began to grow. Roberts almost certainly was aware of it.
There were countless news articles in May warning of damage to the court - and to Roberts' reputation - if the court were to strike down the mandate. Leading politicians, including the president himself, had expressed confidence the mandate would be upheld.
Some even suggested that if Roberts struck down the mandate, it would prove he had been deceitful during his confirmation hearings, when he explained a philosophy of judicial restraint.
It was around this time that it also became clear to the conservative justices that Roberts was, as one put it, "wobbly," the sources said.
Under the mandate, if an individual does not maintain health insurance, the only consequence is that he must make an additional payment to the IRS when he pays his taxes. See §5000A(b). That, according to the Government,means the mandate can be regarded as establishing acondition—not owning health insurance—that triggers a tax—the required payment to the IRS. Under that theory, the mandate is not a legal command to buy insurance.Rather, it makes going without insurance just another thing the Government taxes, like buying gasoline or earning income. And if the mandate is in effect just a tax hike on certain taxpayers who do not have health insurance, itmay be within Congress’s constitutional power to tax.
The question is not whether that is the most naturalinterpretation of the mandate, but only whether it is a “fairly possible” one. Crowell v. Benson, 285 U. S. 22, 62 (1932). As we have explained, “every reasonable construction must be resorted to, in order to save a statute from unconstitutionality.” Hooper v. California, 155 U. S. 648, 657 (1895). The Government asks us to interpret the mandate as imposing a tax, if it would otherwise violate the Constitution. Granting the Act the full measure of deference owed to federal statutes, it can be so read, for the reasons set forth below.
The Affordable Care Act’s requirement that certain individuals pay a financial penalty for not obtaining health insurance may reasonably be characterized as a tax. Because the Constitution permits such a tax, it is not our role to forbid it, or to pass upon its wisdom or fairness.
