With the schools it once ran facing an uncertain future, defunct for-profit operator Education Management Corp. is caught up in an unusual bankruptcy court battle that has lenders trying to oust a veteran trustee, George Miller, WSJ Pro Bankruptcy reported. Neither the lenders nor Miller would discuss the reasons behind the move to replace him as trustee in six of the bankruptcy cases involved in the liquidation of Education Management. Until last year, the company operated one of the nation’s largest chains of for-profit schools, including the Art Institutes chain. In June, Education Management filed for chapter 7 bankruptcy protection, with no schools to operate and little cash. It is the job of the bankruptcy trustee to find cash for creditors, and, in a bare-bones case like Education Management’s, that often means finding someone to sue. Education Management sold the bulk of its schools to a Los Angeles nonprofit, Dream Center Foundation, months before filing for bankruptcy protection in June.
