Premier of the Western Cape Province v The Public Protector and Another

While serving as Premier of the Western Cape, Helen Zille posted a series of tweets in March 2017 reflecting on Singapore’s development and suggesting that some aspects of South Africa’s colonial legacy (such as infrastructure and institutions) had value. The tweets sparked widespread public criticism, with many accusing her of defending or justifying colonialism. Zille issued multiple public apologies acknowledging the offence caused and clarifying that she did not support colonialism. A complaint was lodged with the Public Protector alleging that the tweets breached the Executive Ethics Code. The Public Protector investigated and found that Zille’s conduct violated the Ethics Code and the Constitution, concluding that her tweets were offensive, undermined the integrity of her office, infringed dignity, and fell outside the protection of freedom of expression. Remedial action was directed at the Speaker of the Western Cape Provincial Legislature. Zille sought to review and set aside the findings and remedial action. The High Court declined to do so, holding the matter moot and the alleged legal errors not reviewable. Zille appealed to the Supreme Court of Appeal.

The appeal was upheld with costs, including the costs of two counsel. The High Court’s order was set aside and replaced with an order reviewing and setting aside the specified findings and remedial action in the Public Protector’s Report No. 5 of 2018/19. The Public Protector was ordered to pay the costs of the review application.

The case is significant for reaffirming the high constitutional protection afforded to freedom of expression, particularly political speech by elected officials. It clarifies the narrow scope of section 16(2)(b) of the Constitution and confirms that offensive or controversial speech does not lose protection unless it amounts to incitement of imminent violence or other excluded categories. The judgment also reinforces that findings of the Public Protector are reviewable where they are materially influenced by errors of law, thereby strengthening the principle of legality and judicial oversight over Chapter 9 institutions.
