Conhage (Pty) Ltd (formerly Tycon) required capital to expand its manufacturing business. It entered into two sets of transactions with Firstcorp Merchant Bank Ltd structured as sales of manufacturing plant and equipment followed immediately by leaseback arrangements. Conhage claimed deductions for the lease rentals as expenditure incurred in the production of income under s 11(a) of the Income Tax Act 58 of 1962. The Commissioner for Inland Revenue disallowed the deductions, contending that the transactions were in substance loans and that the agreements were simulated. The Commissioner further invoked the general anti-avoidance provision in s 103 of the Act. Conhage appealed to the Special Income Tax Court, which found in its favour, holding that the transactions were genuine sales and leasebacks and that s 103 was not applicable. The Commissioner appealed to the Supreme Court of Appeal.
