The Department of Correctional Services initiated a procurement process in 2011 to introduce an Electronic Monitoring System (EMS) to monitor parolees. A pilot tender was awarded to ESS in December 2011 at R6,510,375, which was extended three times until June 2014 at a total cost of R14,678,269. A final tender was awarded to ESS in April 2014 and a Service Level Agreement (SLA) valued at R301,611,772 was concluded in May 2014. In August 2016, the Department stopped paying ESS, and in March 2017 cancelled the SLA citing various alleged irregularities. The President issued a proclamation in April 2016 authorizing the SIU to investigate irregularities in the Department's procurement of the EMS. ESS brought an urgent application to enforce the SLA, which was referred to arbitration. The arbitrator ruled in favor of ESS in November 2017. The SIU and Department brought a review application in March 2018 (approximately 7 years after the pilot tender and 4 years after the final tender) seeking to set aside the tender awards and contracts based on alleged irregularities including non-compliance with the SITA Act, the PSIR Act, and alleged fronting regarding a subcontractor, Ekasi.
