You’ll recall that Barack Obama went after ABC News’ George Stephanopoulos for calling the health care mandate a “tax” back in 2009. Stephanopoulos used a dictionary to prove the mandate amounted to a tax, but Obama was offended and completely rejected the premise.

Here’s a sample from the exchange:

OBAMA: No. That’s not true, George. The — for us to say that you’ve got to take a responsibility to get health insurance is absolutely not a tax increase. What it’s saying is, is that we’re not going to have other people carrying your burdens for you anymore than the fact that right now everybody in America, just about, has to get auto insurance. Nobody considers that a tax increase.

People say to themselves, that is a fair way to make sure that if you hit my car, that I’m not covering all the costs.

STEPHANOPOULOS: But it may be fair, it may be good public policy…

OBAMA: No, but — but, George, you — you can’t just make up that language and decide that that’s called a tax increase. Any…

STEPHANOPOULOS: Here’s the…

OBAMA: What — what — if I — if I say that right now your premiums are going to be going up by 5 or 8 or 10 percent next year and you say well, that’s not a tax increase; but, on the other hand, if I say that I don’t want to have to pay for you not carrying coverage even after I give you tax credits that make it affordable, then…

STEPHANOPOULOS: I — I don’t think I’m making it up. Merriam Webster’s Dictionary: Tax — “a charge, usually of money, imposed by authority on persons or property for public purposes.”

OBAMA: George, the fact that you looked up Merriam’s Dictionary, the definition of tax increase, indicates to me that you’re stretching a little bit right now. Otherwise, you wouldn’t have gone to the dictionary to check on the definition.

Well, that was then and this is now. And as expected, Obama was lying. The Obama Administration is now arguing in court that the health care mandate is a tax.

In order to protect the new national health care law from legal challenges, the Obama administration has been forced to argue that the individual mandate represents a tax — even though Obama himself argued the exact opposite while campaigning to pass the legislation.

Late last night, the Obama Department of Justice filed a motion to dismiss the Florida-based lawsuit against the health care law, arguing that the court lacks jurisdiction and that the State of Florida and fellow plaintiffs haven’t presented a claim for which the court can grant relief. To bolster its case, the DOJ cited the Anti-Injunction Act, which restricts courts from interfering with the government’s ability to collect taxes.

The Act, according to a DOJ memo supporting the motion to dismiss, says that “no suit for the purpose of restraining the assessment or collection of any tax shall be maintained in any court by any person, whether or not such person is the person against whom such tax was assessed.” The memo goes on to say that it makes no difference whether the disputed payment it is called a “tax” or “penalty,” because either way, it’s “assessed and collected in the same manner” by the Internal Revenue Service.

So now it’s a  tax. 2009? Totally not a tax. In fact, such a suggestion is offensive. 2010? Obviously it’s a tax. In fact, the Obama Administration will argue as much in court. Apparently someone bought Obama a dictionary for Christmas.
