What could be a reason for a prescribed person's refusal to reinstate a licence?

A prescribed person's refusal to reinstate a licence can indeed be due to a current outstanding suspension order. An outstanding suspension indicates that the individual is still under a disciplinary action or regulatory requirement that prevents them from being qualified to hold a license. Such an order typically arises from past violations of professional standards or regulations, creating a significant barrier to reinstatement.

In contrast, failing to complete professional development is unlikely to be an absolute barrier to reinstatement if the individual is otherwise eligible. Changes in qualifications could potentially affect a person's ability to practice, but the presence of an outstanding suspension order is a more definitive reason for refusal. Lastly, having paid their fees is generally a positive factor that would support reinstatement rather than impede it.
