The Local Government Ombudsman's comeback procedure states:
The term comeback is used when a complaint has been determined without a formal report and the complainant alleges that one or more of the following apply:
1) The complaint, or a material part of it, has not been understood by the commission’s staff;
2) Evidence submitted before termination has not been taken into account;
3) The council has not been telling the true story and evidence of this is provided; or
4) New information has been supplied about the original complaint.
If the complainant meets any one of the stated criteria, the initial decision not to investigate their complaint should be properly reviewed by a senior officer.
