A federal judge has dismissed the lawsuit filed by the children of the late U.S. Magistrate Judge Theodore Klein against the U.S. government, claiming their father’s fatal lung ailment was due to moldy conditions at the David W. Dyer Courthouse in Miami.

Klein died in 2006 at 66 from a severe respiratory infection. His children blamed the courthouse’s condition on poor maintenance by the General Services Administration, which operates all federal courthouses. The Dyer courthouse was plagued for years with water leaks and mold that worsened after a spate of hurricanes hit South Florida in 2004 and 2005. It has since been shuttered.
