For the third time in as many months, a federal judge has summarily dismissed a securities class action lawsuit against a former Fannie Mae executive. U.S. District Judge Richard Leon threw out the case against Leanne Spencer, Fannie’s former controller, brought nearly a decade ago by investors hoping to recover damages. Two Ohio pension funds – the Ohio Public Employees Retirement System and the State Teachers Retirement System of Ohio – filed suit in 2004 related to a $6.3 billion overstatement of earnings against Fannie and three former GSE executives, including CEO Franklin Raines.
