Chief B.J. Wilkinson pleaded no contest to charges of obstructing government operations last month.
He was sentenced to 30 days in the Cheyenne County Jail.
Wilkinson was supposed to being serving the sentence this week, but that was put on hold when his attorney filed papers challenging the sentence.
Wilkinson had been accused of failing to pursue criminal charges against Sidney Public Works Director John Hehnke after Hehnke’s ex-girlfriend filed a complaint.
