Powernet Services 1988 (Pty) Ltd v Government of the Republic of South Africa (559/95) [1997] ZASCA 82; 1998 (2) SA 8 (SCA); [1997] 4 All SA 676 (A); (26 September 1997)

Powernet Services 1988 (Pty) Ltd v Government of the Republic of South Africa (559/95) [1997] ZASCA 82; 1998 (2) SA 8 (SCA); [1997] 4 All SA 676 (A); (26 September 1997)

The court held that the contract, properly interpreted in light of its technical language and background facts, required Powernet to supply a fourth-generation programming language suitable for developing the census capture and edit program. The specification indicated that the system had to support 250 terminals simultaneously, performing 20 transactions per second, using software developed in a fourth-generation language. Powernet's argument that the requirement was optional or limited to later programs was rejected. The supplied system did not meet these requirements, and the government was entitled to cancel the contract under the lex commissoria. The appeal was dismissed with costs.
