Key member of trial team that represented Anthem, Inc. against claims brought by the US Department of Justice to block Anthem's US$54 billion acquisition of Cigna Corporation.
Following trial, an expedited appeal to the D.C. Circuit was filed. The D.C. Circuit granted expedition, reviewed the appeal, heard oral argument and ruled on the merits, all within the span of two and a half months. This was the first time the D.C. Circuit has ever granted and heard an expedited appeal of a merger matter in such a compressed time frame, paving the way for more merger review in this appellate court. After receiving a split in the D.C. Circuit and a highly favorable dissent, Anthem filed a petition for a writ of certiorari to the Supreme Court only one week later.
