Filed Oct. 31 in Riverside County Superior Court, the lawsuit alleges that Dr. Kali P. Chaudhuri, who is a majority stakeholder in the Integrated HealthCare Holdings, Inc. (IHHI), which owns the Western Medical Centers of Anaheim and Santa Ana, Chapman Medical Center in Orange and Santa Ana's Coastal Communities Hospital, has "engaged in fraud, racketeering and corruption" in his dealings with local physicians' groups, thereby threatening the health care of thousands of patients.
