MADISON, Wis. – Final bill: $24,315.

That’s how much taxpayers in the Middleton-Cross Plains Area School District paid for the services of Karen Mawhinney, the arbitrator who ordered the reinstatement of a seventh-grade science teacher fired for viewing multiple pornographic images and videos at school.

The total bill was $48,600, split between the school district and the Middleton Education Association, the teachers union that represented Andrew Harris in what arbitration experts, including Mawhinney, described as an “extraordinary” process.
