The binding legal principles established are: (1) The Regional Manager's function under section 22 of the MPRDA is purely mechanical and clerical, involving verification of formal compliance with no exercise of discretion. (2) The doctrine of functus officio applies only to final decisions; it does not apply to preliminary, mechanical administrative steps that form part of a larger decision-making process. (3) Where an application complies with the MPRDA but is partially rejected due to an administrative error by the Regional Manager, the application remains valid and can be corrected without losing its position in the section 9 queue, provided there is ongoing engagement to resolve the error. (4) A decision-maker granting condonation for late filing of an appeal must apply their mind to all relevant factors including the extent and cause of delay, its effect, the reasonableness of explanation, importance of issues, and prospects of success (Aurecon factors). Failure to do so renders the decision reviewable as materially influenced by error of law. (5) The Regional Manager's decision to accept or reject an application under section 22, though preliminary and mechanical, constitutes administrative action with direct legal effect subject to review under PAJA.
