In the appeal, filed March 5, Dr. Earl Bradley's public defenders say that Delaware State Police searched places at the physician's office that were not listed on a search warrant. The search turned up video evidence of Bradley molesting children.
The Delaware Attorney General's Office declined to comment. Prosecutors must file a response by April 4.
Last year, Bradley was sentenced to 14 life sentences without parole for 14 counts of first-degree rape. He also was sentenced to more than 160 years in prison for multiple counts of assault and sexual exploitation of a child.
