In his report  on the pro-business tilt of the U.S. Supreme Court in Sunday’s New York Times, Adam Liptak confirmed what we reported  back in April: that the court hears conservative voices weighing in on cases in the form of friend-of-the-court briefs far more often than it hears liberal voices.
The Chamber of Commerce tops the list this term, as the Constitutional Accountability Center points out in this report  :
All told, the Chamber of Commerce has filed a whopping 18 amicus briefs this Term – just below its record number of 21 in October Term 2010. Overall, the Court will likely decide 76 cases this Term, meaning that the Chamber will have participated in roughly 24% of the Court’s decided cases.
And the court has ruled in favor of the position advocated by the Chamber in six of seven cases so far, with many decisions still pending, adding to its winning record since 2006:
All told, since early 2006, the Chamber has won 79% of close cases decided by the Roberts Court (22 of 28) – that is, cases decided with a five-Justice majority. And, in these close cases, when a Justice’s vote matters the most, support for the Chamber’s position from the Court’s conservative bloc has been overwhelming.
