The American Bar Association, the Washington Legal Foundation, the U.S. Chamber of Commerce, and Chicago-based DRI – The Voice of the Defense Bar this week formally added their heavyweight voices to a request that the U.S. Supreme Court review a lower court ruling that let federal prosecutors subpoena documents which foreign companies had sent to law firms in the United States.
