Sections 417 and 418 of the Companies Act 61 of 1973 are complementary provisions that must be read together. The Master, when convening an enquiry under s 417, has inherent discretionary power (equivalent to that of the court) to determine how the enquiry should be conducted, including who may interrogate witnesses. The absence of an express provision in s 417 (comparable to s 418(1)(c)) allowing liquidators and creditors to interrogate witnesses does not restrict the Master's discretion, because the Master possesses inherent discretionary power that does not require statutory expression. Section 418(1)(c) was necessary to extend interrogation powers to commissioners who, as delegatees, have no inherent powers. A purposive and contextual interpretation of s 417, having regard to its legislative history and objectives, permits the Master to allow liquidators, creditors and their representatives to interrogate witnesses at a s 417 enquiry. A literal interpretation that would restrict interrogation to the Master alone would be inconsistent with the purpose of the provision and would produce absurdity.
