South African court upholds common law abuse of process as defense in prototypical anti-enviro SLAPP

The Constitutional Court of South Africa upheld the use of common law abuse of process in defense of environmental activists against a defamation claim by a mining company.

I wrote about this case in its lower court iteration in 2021. The plaintiff mining company rather boldly sued the environmentalists to chill their activism with the burdens of litigation. Deputy Judge President of the Western Cape High Court Patricia Goliath employed a creative adaptation of common law abuse of process—conventionally a tort, not a defense—to work in the case like an anti-SLAPP law, which South Africa does not have as a matter of statute.

I have written at length on anti-SLAPP cases. I am not a fan of anti-SLAPP laws, but acknowledge that they can function well to protect the freedoms of expression and petition in cases that fit the historical pattern for which anti-SLAPP was conceived. Protecting environmentalists against developers is the very prototype, so I lauded DJP Goliath's decision.

In November 2022, the Constitutional Court upheld the abuse-of-process theory. The court expressly recognized the abuse-of-process defense as an anti-SLAPP measure and an evolution of common law. The court rejected the mining company's objection to the adaptations required to make abuse of process work. The common law test for the tort in South Africa requires that a claim have a near certainty of failure; the court refused to hold the defendant environmentalists to that burden. The common law test also did not allow abuse of process to be determined wholly upon ulterior motive. The court ruled that ulterior motive could support the abuse-of-process defense.

As I wrote in 2021, I prefer the common law approach to the blunt and overbroad device of statutory anti-SLAPP that prevails in the United States. The South African approach takes care to assess the power imbalance between the litigants to ensure conformity with the anti-SLAPP pattern. In the United States, anti-SLAPP is distorted to empower media conglomerates and public figures to extract high-dollar attorney fee awards from genuinely injured claimants who can't meet extraordinary requirements of proof upon mere pleading.

The case is Mineral Sands Resources (Pty) Ltd v Reddell, (CCT 66/21) [2022] ZACC 37; 2023 (2) SA 68 (CC) (14 November 2022). Justice Steven Arnold Majiedt authored the unanimous judgment.
