The appellants (Netstar, Matrix, and Tracker) were major providers of stolen vehicle recovery (SVR) systems in South Africa. From approximately 1996-1999, at the urging of the South African Insurance Association (SAIA), which wanted uniform standards for SVR systems to reduce theft claims, various SVR providers participated in workshops under the auspices of the Vehicle Security Association of South Africa (VESA) to develop performance standards for SVR systems. In February 1999, a SVR committee was established within VESA with membership and accreditation dependent on meeting certain performance criteria: a minimum of 3000 subscribers, at least one year in operation, 100+ recoveries, and specific recovery rates. Most major insurers required VESA accreditation for premium discounts. A category of provisional approval existed initially but was discontinued in April 2000 at SAIA's insistence. In July 2003, membership criteria were relaxed to allow a R2 million guarantee as an alternative to performance criteria. The appellants withdrew from VESA in May 2004. Tracetec complained to the Competition Commission that the standards constituted an anti-competitive agreement preventing new entrants from accessing the market.
