On December 15, 2014, the United States Supreme Court decided that a party seeking to remove a class action to federal court need not include evidence of the amount in controversy as part of its petition for removal. Instead, the party seeking removal need only plausibly state that the amount at stake exceeds $5 million. The case is Dart Cherokee Basin Operating Co. LLC v. Owens, 574 U.S. ---, 2014 U.S. LEXIS 8435 (2014).
