The suit alleges Leventhal and other shareholders he is representing have lost "tens of millions of dollars" through alleged corporate mismanagement by Post executives. Post officials did not respond to an e-mail request by GlobeSt.com for comment on the suit. Leventhal is director of Interfinancial Properties Inc. in Marietta, GA.

Leventhal tells GlobeSt.com he has asked for the Post's internal information for the past six months. "My request for documents to be produced was initially thwarted by [Post] senior management who shrugged off the very minority shareholders as insignificants beneath their feet as they fly over us in their corporate jets," Leventhal says.

"Fortunately, there is at least some justice in that Post, through its seven lawyers who attended one hearing with me, consented to a Federal Court order to provide certain documents about the company's accounting operations," Leventhal tells GlobeSt.com. Those documents can't be disclosed by Leventhal to anyone except his lawyers, advisors, consultants and other experts hired by Leventhal, the court order states.
