Can the university exclude me for financial debt?
A university may withhold registration (and therefore prevent return) for outstanding fees — but this is different from academic exclusion. Financial exclusion is a separate issue. If the exclusion is academic, financial debt is not a valid basis. If it is financial, explore NSFAS, bursaries, or payment arrangements.
Can I interdict the university from excluding me while I appeal?
Yes. If the exclusion takes immediate effect and you have a genuine appeal pending, you can apply to the High Court for an urgent interdict to suspend the exclusion pending the outcome of the appeal. This has been successfully done at several South African universities.
