Supreme Court Justice Antonin Scalia criticized the court's recent health care ruling again, calling Chief Justice John Roberts' decision to uphold the law as a tax incorrect.

The biggest issue within President Obama's health care law was the "individual mandate" requiring all Americans to have health insurance or face a penalty.

"There is no way to regard this penalty as a tax. It simply doesn't bear that meaning," Scalia told Fox News Sunday. "In order to save the constitutionality, you cannot give the text a meaning it will not bear."

Scalia has been viewed as a conservative champion on the court. Roberts is also a conservative but sided with the four liberal justices to uphold the constitutionality of the health care law.

During his interview, Scalia also made unexpected comments on gun control.

In light of the July 20 Colorado theater massacre, Scalia was asked whether legislatures could ban the sale of semiautomatic weapons.

Scalia said some gun control laws may be acceptable.
