A study condicted by the Constitutional Accountability Center came up with a finding which is not altogether surprising, but depressing nevertheless:
The U.S. Chamber of Commerce is undefeated at the Supreme Court this term, continuing to improve its success in securing business-friendly judgments since Chief Justice John Roberts took the bench in 2005.
In other words, when the conservative pro-business lobby known as "The U.S. Chamber of Commerce" filed a friend-of-the-court brief urging to the court to take a particular position in a particular case, the court always ended up taking that position this term (so far).
By comparison, from 1994 to 2005, when Rehnquist was chief justice, the chamber succeeded in roughly 56 percent of the cases it backed. The business lobby had roughly a 43 percent success rate from 1981 to 1986 during the final years of Chief Justice Warren Burger's tenure.
