Back in November 2008, animal rights advocates and organizations were disappointed when the trial of Ringling Barnum & Bailey Circus didn't begin as scheduled due to another dilatory tactic by the defendants. They introduced another set of experts that necessarily had to be vetted, or cross-examined, by the plaintiffs before the trial could begin. Ringling has successfully delayed their court appearance by several years by employing such dilatory tactics. In August 2007, Tracy Silverman , General Counsel for the Animal Welfare Institute , said "After five years of legal wrangling, we look forward to unveiling the curtain at trial to expose the suffering and death of elephants at the hands of the so-called 'Greatest Show on Earth". These magnificent animals will finally have their day in Court." Back then, Judge Emmet Sullivan of the federal district court in Washington D.C. scolded the circus for "wasting a considerable amount of time and resources"
