A shareholder of Boca Raton, Fla.-based Eclipsys Corp. is suing 20 of the company’s past and current officers and directors for allegedly defrauding the company and its stockholders of millions of dollars on falsely backdated stock options to one another.

The suit, filed in U.S. District Court in West Palm Beach, alleges that “from at least 1999 until 2006, a majority of Eclipsys directors, together with top officers, engaged in a secret scheme to grant undisclosed, in-the-money stock option grants to themselves and others by backdating stock option grants to coincide with historically low closing prices of Eclipsys’s common stock.”
