Kentucky Treasurer Allison Ball filed legal papers today to overturn the state pension system’s payment of $50,000 to cover the cost of its ousted chairman’s lawsuit against Gov. Matt Bevin. Bevin removed the former chairman, Louisville banker Tommy Elliott, from the Kentucky Retirement Systems Board of Trustees in April — three years before his term expired. Elliott and another trustee sued the governor and KRS in Franklin County Circuit Court in June, seeking to restore Elliott to the board. KRS paid their legal bill of $50,000, saying state law calls for the agency to pay for legal costs “arising from the performance” of trustee duties. Ball, a Republican first-termer like Bevin, disagrees.
