(CNN) - Mitt Romney on Monday fired back at President Barack Obama, who earlier in the day described the largely conservative push on the Supreme Court to overturn the Affordable Care Act as "judicial activism."
Typically, conservatives level the partisan term at liberal justices whom they accuse of ruling based on political agenda, rather than the Constitution. In this case, Obama turned the criticism around.
"I just remind conservative commentators that for years, what we've heard is, the biggest problem on the bench was judicial activism or a lack of judicial restraint, that an unelected group of people would somehow overturn a duly constituted and passed law," the president said, adding he firmly believed the law will be upheld.
During an interview with Fox News on Monday night, however, Romney laughed when asked about Obama's comments.
"Isn't this wonderful to have a liberal talking about judicial activism?" Romney said.
He added that he found it puzzling the president was concerned the Supreme Court "might apply the Constitution to the bill he passed."
"The purpose of the Supreme Court is to make sure that Congress does not pass laws that are in violation of the Constitution," Romney said. "So judicial activism is not following the Constitution. Judicial activism is departing from the Constitution"
Romney continued: "If the president complains about a Supreme Court following the Constitution, he is coming from a different world than the world that the founders and the judicial history has described for America."
The Supreme Court's decision is expected to be made public in June.
