IndyStar.com:  “Bren Simon [wife of deceased billionair Melvin Simon] has filed a counterclaim against the company her late husband co-founded, charging Simon Property Group with breach of agreement for refusing to give her stock or cash for her partnership holdings.  She also contends that her stepson, the Indianapolis-based company's chairman and CEO, David Simon, is behind the denial.  The counterclaim ratchets up the stakes in a growing legal battle over the $1 billion-plus estate of Melvin Simon, who died in September at 82.”
