148 annual report 2013 The Ombudsman stated that the notice had been too short. In his opinion, it would have been most compliant with good administrative practice if the school had fixed a slightly later starting date. He found that it would have served the welfare of the boy better if the school had given a slightly longer notice. In this context, the Ombudsman referred to Article 3(1) of the UN Convention on the Rights of the Child. 2013-3. Repayment of overpaid salary For almost a year, a kindergarten teacher without any work experience was erroneously paid a salary supplement for respectively six and ten years’ work experience. The kindergarten teacher discovered the error himself and informed his employer. His employer stopped future payments of the supplement and at the same time demanded that the erroneously paid amount of a little over DKK 20,000 be repaid. The kindergarten teacher’s union complained on his behalf to the Ombudsman about the repayment claim. The Ombudsman found no grounds for criticising the employer’s specific decision to demand repayment. In this context, the Ombudsman emphasised that he could not criticise the case investigation, including the fact that the employer had not considered the decision to demand repayment to be a decision within the meaning of the Public Administration Act. 2013-12. Invalid exemption from participation in household rubbish collection service A couple complained to the Ombudsman because their municipality had informed them that an exemption from participation in (and payment for) the household rubbish collection service provided by the municipality which they were granted in 1989 by their former municipality (before the local government reform) could not be maintained. The couple still did not wish to participate in, nor pay for, the rubbish collection service. In the Ombudsman’s opinion, the original exemption granted to the couple by their former municipality was invalid. The Ombudsman therefore agreed with the decision of the couple’s current municipality that the exemption could not be maintained.
