Arizona prison officials are appealing a large fine state workplace safety regulators levied against the Corrections Department for failing to protect a teacher who was raped by an inmate.

The appeal filed last week seeks a hearing before an administrative law judge to overturn the $14,000 penalty issued by the Industrial Commission of Arizona.

Documents obtained by The Associated Press show commissioners greatly boosted the fine their inspector recommended at a hearing last month. One said the workplace-safety violations their inspectors found showed the rape "should never have occurred in this facility."

The teacher was attacked by a convicted rapist in January 2014 and is suing top officials at the Eyman prison in Florence for failing to protect her. A federal judge allowed that lawsuit to proceed on Thursday.
