Do you remember how much criticism the Solicitor General received from some after oral argument. Many said that not only was he stumbling and ineffective but his seemingly contradictory arguments on the tax issues were lame. Well, it appears that ineffective and lame won the day.
Here is the relevant language from the Roberts opinion. First, the Court sets up the issue,
Government’s tax power argument asks us to view the statute differently than we did in considering its com- merce power theory. In making its Commerce Clause argument, the Government defended the mandate as a regulation requiring individuals to purchase health insurance. The Government does not claim that the taxing power allows Congress to issue such a command. Instead, the Government asks us to read the mandate not as ordering individuals to buy insurance, but rather as imposing a tax on those who do not buy that product.Then he explains that the Court must find any reasonable reading that allows a law to be sustained,
The text of a statute can sometimes have more than one possible meaning. To take a familiar example, a law that reads “no vehicles in the park” might, or might not, ban bicycles in the park. And it is well established that if a statute has two possible meanings, one of which violates the Constitution, courts should adopt the meaning that does not do so. Justice Story said that 180 years ago: “No court ought, unless the terms of an act rendered it unavoidable, to give a construction to it which should involve a violation, however unintentional, of the constitution.” Parsons v. Bedford, 3 Pet. 433, 448–449 (1830). Justice Holmes made the same point a century later: “[T]he rule is settled that as between two possible interpretations of a statute, by one of which it would be unconstitutional and by the other valid, our plain duty is to adopt that which will save the Act.” Blodgett v. Holden, 275 U. S. 142, 148 (1927) (concurring opinion). The most straightforward reading of the mandate is that it commands individuals to purchase insurance. After all, it states that individuals “shall” maintain health insurance. 26 U. S. C. §5000A(a). Congress thought it could enact such a command under the Commerce Clause, and the Government primarily defended the law on that basis. But, for the reasons explained above, the Commerce Clause does not give Congress that power. Under our precedent, it is therefore necessary to ask whether the Government’s alternative reading of the statute—that it only imposes a tax on those without insurance—is a reasonable one.Then he analyses the law to discern its essence as a tax,
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 a condition—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, it may be within Congress’s constitutional power to tax. . . . . . The exaction the Affordable Care Act imposes on those without health insurance looks like a tax in many re- spects. The “[s]hared responsibility payment,” as the statute entitles it, is paid into the Treasury by “tax- payer[s]” when they file their tax returns. 26 U. S. C. §5000A(b). It does not apply to individuals who do not pay federal income taxes because their household income is less than the filing threshold in the Internal Revenue Code. §5000A(e)(2). For taxpayers who do owe the pay- ment, its amount is determined by such familiar factors as taxable income, number of dependents, and joint filing status. §§5000A(b)(3), (c)(2), (c)(4). The requirement to pay is found in the Internal Revenue Code and enforced by the IRS, which—as we previously explained—must assess and collect it “in the same manner as taxes.” Supra, at 13–14. This process yields the essential feature of any tax: it produces at least some revenue for the Government. United States v. Kahriger, 345 U. S. 22, 28, n. 4 (1953). Indeed, the payment is expected to raise about $4 billion per year by 2017. Congressional Budget Office, Payments of Penalties for Being Uninsured Under the Patient Pro- tection and Affordable Care Act (Apr. 30, 2010), in Selected CBO Publications Related to Health Care Legislation, 2009–2010, p. 71 (rev. 2010).Finally, he explains that the fact it is labeled as a "penalty" does not mean it isn't a tax for this purpose
It is of course true that the Act describes the payment as a “penalty,” not a “tax.” But while that label is fatal to the application of the Anti-Injunction Act, supra, at 12–13, it does not determine whether the payment may be viewed as an exercise of Congress’s taxing power. It is up to Congress whether to apply the Anti-Injunction Act to any particular statute, so it makes sense to be guided by Con- gress’s choice of label on that question. That choice does not, however, control whether an exaction is within Congress’s constitutional power to tax.Although many thought the Solicitor General's argument was bizarre and convoluted, it won the day.
