“One member of Carnegie’s board said Mr. Perelman might have decided to step aside next month because he was unlikely to be re-elected. The board member, who spoke on the condition of anonymity, said the trustees had felt blindsided this summer when Mr. Perelman briefly suspended Mr. Gillinson. The board member added that while they would investigate the concerns he raised, they did not believe that Carnegie had governance or transparency problems, and denied that the board had been dragging its feet on hiring a lawyer to investigate.”
