Class action certification and constitutional claims: The South African case
Bibliographic record
Abstract
This article considers whether, in the case of South African, there is a valid basis for requiring certification of certain types of class actions only. Specifically, the article will consider whether a preliminary certification requirement should apply to constitutional claims against the government in the same way it applies to other class actions. To determine this issue, the purpose of certification is considered with a view to establishing whether said purpose is only given effect to in certain circumstances. If certification would serve no purpose in the context of Bill of Rights claims or claims which display a public character, it may be prudent not to require class action certification in such cases. Conversely, if certification would still serve a purpose in those types of cases, it should remain part of class proceedings. To assist in making this determination, the position in several European jurisdictions, Ontario and the United States is considered.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
