The Evolution of the Class Action Trial in Ontario
Bibliographic record
Abstract
Only a few short years ago, there was a nearly universal view among practitioners in the class actions field: any class action case that could be certified was almost surely going to settle. The fact of the matter, however, is that this universal view is incorrect. Full-blown class action trials have been occurring in Canada for decades. The authors of this paper embarked on an investigative research project in 2011, aimed at discovering, to the greatest extent possible, all class action matters across the country that had been tried since the advent of class action legislation. Because there were no sources of consolidated information, the investigation required both conventional and unconventional research techniques. This paper will describe the investigation and its surprising results, suggest techniques for trial management, and conclude that class action proceedings have evolved into a healthy process for trial resolution.

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.
