ADM.6:5.2 - A settled negative and a genuine alternative basis

A request for 25 September cites only an appointment effective on 1 October. The service rule requires an effective appointment at use and prescribes a response explaining the failed condition. ADM.3 supplies the negative temporal result; the handler issues that response. No further eligibility decision is needed for the supplied appointment.

The requester then identifies a different appointment said to begin on 1 September, but the relevant decision and scope are unavailable. The new question goes to its issuing office: does that appointment cover this person, work and requested date? If an adequate existing decision is recovered, use it. If it is not recovered, preserve the gap. The later descriptive record of a valid September appointment would not itself make that appointment begin later.
