It’s a far cry from "The Greatest Show on Earth," but litigation over the Ringling Bros. and Barnum & Bailey circus’ treatment of elephants has certainly been a three-ring (and then some) affair.

After animal rights groups unsuccessfully sued circus producer Feld Entertainment Inc. in the U.S. District Court for the District of Columbia, Judge Emmet Sullivan ordered the plaintiffs on March 29 to cover Feld’s attorney fees. Sullivan put off a decision on the amount for a later date, but Feld said in filings that it had spent more than $20 million defending the case during the past decade.
