Tom Girardi will have to spend more time in a federal medical prison facility after delays with a court-ordered mental evaluation prompted a federal judge on Thursday to extend the procedure another 15 days.

Girardi, 85, who suffers from dementia, was transported on Jan. 7 to Butner, North Carolina, after U.S. District Judge Josephine Staton, in the Central District of California, ordered the psychological and psychiatrist examination under Section 4244 of Title 18, which states that a judge can require that a criminal defendant with “a mental disease or defect” serve his prison sentence in a facility, such as a hospital, that provides suitable treatment. The evaluation was set to last 30 days, after which Girardi was to return to Los Angeles to face sentencing.
