WASHINGTON — A study from a liberal interest group says the Supreme Court of Chief Justice John Roberts has a decidedly pro-business tilt, echoing the line Democrats are taking in support of the nomination of Elena Kagan to fill its latest vacancy.

The analysis from the Constitutional Accountability Center finds that the court's five conservative justices side with the U.S. Chamber of Commerce at least two-thirds of the time, while the four liberal justices all disagree with the position by the nation's largest business group more than half the time.
