(CNN) -- Legal scholars expressed little surprise Thursday over the fact that it was the conservative chief justice of the United States -- John G. Roberts Jr. -- who proved to be the key vote in upholding the constitutionality of the Affordable Care Act.
"Had the court ruled as the four dissenters would have had it -- in a 5-4 decision, red versus blue -- that the signature act of a Democratic administration was unconstitutional, I think that would have been a very serious threat to the legitimacy of the court," said Timothy S. Jost, a professor at Washington and Lee University School of Law in Washington.
"I think Americans are already very skeptical about the rule of law in the United States and and believe that the court is essentially a third political branch," he said in a telephone interview.
The 57-year-old Roberts may have been thinking about the court's perceived legitimacy and about his own legacy when he was crafting the decision, which couldn't have been an easy one, Jost said. "I think he probably had to think very long and hard about how to rule in this case."
When Roberts was tapped in 2005 by then-President George W. Bush to be the 17th chief justice of the United States, then-Sen. Barack Obama voted against his confirmation. Since then, Roberts' stances on campaign finance and affirmative action had led some observers to brand him a judicial activist.
But Neal Katyal, a professor of law at Georgetown University in Washington, said that Roberts, "more than almost any justice on the court today, appreciates the institutional role of the Supreme Court and American democracy. He's a student of history and I think today's decision was a really resounding reflection of the chief justice's values, which are (that) law is not just politics and the Constitution is not just politics, and we should think about decisions impartially and dispassionately and come to the right ones."
Katyal, who served in the Justice Department under the Clinton administration, called Thursday's decision "a resounding victory for the rule of law in America."
"I wasn't that surprised" at the decision, said Randy E. Barnett, a law professor at Georgetown who helped write the brief for the National Federation of Business that challenged the law. "I said from day one that the Supreme Court always bends over backwards to uphold laws of Congress. That's the reason why our fight was always an uphill fight."
The law's ultimate fate, he predicted, will be decided not in any court but at the ballot box in November. "The people will decide whether they approve of this tax, this so-called tax that has been imposed upon them," he said in a telephone interview.
And the election may also be about appointing justices who do not bend over backwards to uphold the laws of Congress, he said, "because the Congress cannot be the judge of the scope of its own powers, and we need an independent judiciary to do that."
