PRASA, an organ of state, concluded a series of high-value contracts with Siyangena Technologies for the supply, installation and maintenance of an integrated security access management system at railway stations. These contracts, ultimately worth approximately R5.5 billion, were concluded without compliance with constitutional and statutory procurement requirements, including competitive bidding, budgetary approval, and oversight by relevant committees. Following the appointment of a reconstituted PRASA board and the exposure of widespread maladministration and corruption under its former leadership, PRASA brought a self-review application to have its own procurement decisions set aside. The High Court declared the contracts unconstitutional and invalid and ordered a remedial process involving an independent engineer to assess the value of work performed. Siyangena accepted the invalidity of the contracts but appealed against the remedial order, contending that it was an innocent contracting party and should not be deprived of contractual benefits.
