MADISON, Wis. — The Wisconsin Department of Public Instruction will not revoke the license of a teacher who viewed pornographic emails at work, despite Gov. Scott Walker’s request that swift action be taken to revoke the license.

Andrew Harris was fired in 2010 from his job as a teacher at a Middleton middle school after being accused of receiving and sharing explicit emails while on the job.

Arbitrators ruled the school district wrongly fired Harris and he returned to the classroom in January.

WISC-TV reports Thursday that DPI sent a letter this week saying that while Harris’s conduct was “highly inappropriate,” it does not meet the legal definition of immoral conduct as the law stood at the time.

In 2011 the law was changed to define immoral conduct.
