Sheriffs are creatures of statute and have no inherent powers, only those expressly or by necessary implication conferred by statute. In the absence of authorisation from a magistrate under section 14(7) of the Magistrates' Court Act 32 of 1944, a sheriff is not entitled to: (a) refuse to serve or execute court process unless upfront payment of anticipated fees and charges is made; or (b) withhold the return of service until payment of fees and charges specified therein have been paid. The legislative framework, comprising the Magistrates' Court Act, the Magistrates' Court Rules (particularly Rules 8(2), 8(6), 9(17A)(a), and 34), and the Sheriffs Act, requires that: (i) court processes be served or executed "without any unreasonable delay"; (ii) sheriffs specify their charges on the return of service "after service or attempted service"; (iii) returns of service be furnished "without delay"; and (iv) disputes about fees and charges be resolved through taxation after service has been effected. Demanding upfront payment and refusing to serve process or provide returns of service pending payment is inconsistent with this legislative framework, causes unreasonable delays in the administration of justice, and amounts to unlawful self-help. Section 14(7) provides the only statutory mechanism for a sheriff to refuse service in respect of unpaid fees for services rendered more than three months previously, and only upon obtaining prior authorisation from a magistrate.
