/*Bullock*/ first obtained a restraining order in California against Weldon in 2003, but that order expired last year.
According to the court filing, Weldon turned up in a Wyoming emergency room last month complaining of anxiety and sleeplessness. He later told hospital staff that he had driven from Tennessee in an attempt to meet Bullock at her home in Jackson Hole, Wyo.
He voluntarily entered a mental institution in Tennessee, and the actress sued the state in 2006 to require them to notify her of his release.
A hearing for a three-year order against Weldon was scheduled for Aug. 6.
