City of Johannesburg Metropolitan Municipality v Engen Petroleum Limited

From 1992 to 1994, the City Council of Sandton (now City of Johannesburg Metropolitan Municipality) effected substantial construction changes to Grayston Drive at its intersection with Katherine Street. The construction elevated four lanes of Grayston Drive (two in each direction) above Katherine Street, creating a flyover, while one lane on the southern side and two on the northern side remained at ground level. Sandton Gate Service Station CC owned a petrol filling station on the south west side of Grayston Drive at the intersection with Katherine Street. Sandton Gate was supplied with petrol by Engen Petroleum Ltd. The respondents claimed that the construction work constituted a diversion or closure of lanes in Grayston Drive, which impeded vehicle access to the filling station, resulting in decreased sales and financial losses. The City Council admitted it did not comply with notice requirements under s 67(2) and (3) of the Local Government Ordinance 17 of 1939 (T), which required notice to affected property owners/occupiers about the diversion. The City Council argued it did not need to give notice because there was no permanent closure or diversion.

• Whether the elevation of four lanes of Grayston Drive above Katherine Street amounted to a permanent diversion of a portion of the road for the purposes of s 67 of the Local Government Ordinance 17 of 1939 (T)
• Whether 'diversion' under s 67 of the Ordinance is limited to horizontal/lateral changes or includes vertical changes (elevation or depression of a road)
• Whether the construction work triggered the notice and compensation provisions of s 67 of the Ordinance

The appeal was dismissed with costs, including costs of two counsel.

The elevation of lanes of a road creating a flyover constitutes a 'permanent diversion' of a portion of that road for purposes of s 67 of the Local Government Ordinance 17 of 1939 (T). The term 'diversion' in s 67 is not limited to horizontal or lateral changes to a road; it includes vertical changes (elevation or depression) where such changes materially alter access to abutting properties. The proper interpretation of 'diversion' must be determined by examining the purpose of s 67 in its statutory context - to compensate persons who suffer pecuniary loss due to road changes that adversely affect their property interests - rather than by strict adherence to dictionary definitions or reliance on whether a two-dimensional general plan requires amendment. Where a physical change to a road (whether horizontal or vertical) has the effect of materially altering access to adjacent properties and potentially causing financial loss to owners, lessees or occupiers, that change falls within the ambit of s 67 and triggers the notice and compensation provisions.

The court made several non-binding observations: (1) If the four lanes had been built underground in a tunnel rather than elevated on a flyover, this would also constitute a diversion, contrary to the City Council's argument. (2) Dictionary definitions, while useful guides to word meaning, are not decisive; the task of interpretation requires ascertaining meaning in context. (3) Whether or not a change is reflected on the general plan cannot be determinative of whether there has been a diversion, as s 67(10) only requires supplying a diagram to the Surveyor General after work is completed, and the question of diversion is one of fact. (4) The court suggested that limiting s 67(4) to horizontal diversions would give rise to absurdity and inequitable results, as property owners would be compensated for horizontal road relocations affecting their business but not for vertical relocations with identical effects.

This case establishes an important precedent in South African local government law regarding the interpretation of road diversion provisions. It clarifies that 'diversion' under s 67 of the Local Government Ordinance 17 of 1939 (T) is not limited to horizontal or lateral changes to a road but includes vertical changes such as elevation or depression of a road surface. The judgment adopts a purposive approach to statutory interpretation, focusing on the legislative purpose of protecting and compensating affected property owners rather than narrow dictionary definitions. The case is significant for property owners adjacent to roads undergoing major infrastructure changes, as it confirms their right to compensation when vertical road modifications materially affect access to their properties, even where the road continues in the same general direction. It reinforces the principle that local authorities must comply with notice and compensation procedures under s 67 when road works materially affect property access, regardless of whether the diversion is horizontal or vertical.
