Reading the data

Two kinds of absence, and they differ. not published means the source body publishes no figure — a fact about the source, never a zero. A real zero is written 0, and both appear in the finance file. An empty cell means the column does not apply to that row: in the Australian file penalty_units is empty for NSW, the ACT and South Australia because those jurisdictions legislate fixed dollar amounts rather than penalty units.

The win-rate file. Grounds are keyword-detected from the adjudicator's written reasons, so a ground appearing means it was discussed, not that the case turned on it. Segments with fewer than 10 decisions are excluded. win_rate_pct counts allowed plus not-contested as a win. It is derived analysis, not a republication of the decisions: the decision text belongs to the tribunals that wrote it and is not redistributed here.

A note on filenames

The files on this Hub mirror have had their hyphens stripped by the upload (appealwinratesbysegment.csv). The canonical names, used by the DOI records and every other mirror, keep the hyphens (appeal-win-rates-by-segment.csv). The table above uses the canonical names. Cite those.
