The 15 year saga of the Estate of Anna Nicole Smith vs. the Estate of J. Howard Marshall continues. The U.S. Supreme Court agreed to hear the appeal filed by Smith's estate after it lost an appeal to the 9th Circuit Court of Appeals. Anna's former billionaire husband died and left all of his estate to his son E. Pierce Marshall who died in 2006. Anna died in 2008. Despite the deaths of the three principal players in this long-running dispute, their estates are still duking it out in court.
