A new study has confirmed that the Supreme Court under Chief Justice John Roberts is increasingly siding with the interests of corporate America. The Roberts court has ruled for business interests 61 percent of the time over the past five years. Under Chief Judge William Rehnquist, big business won 46 percent of the time. The new study by the New York Times also confirms the increasing power the Chamber of Commerce has over judicial decisions. In the last term, the Chamber filed briefs in 16 cases. Its side won 13 times, most significantly in the Citizens United case that allows corporations to spend unlimited amounts of money on election campaigns.
