17,000+ published decisions from five NSW courts (Supreme Court, Court of Appeal, Court of Criminal Appeal, District Court, Land and Environment Court), January 2021 to August 2026.

Metrics derived: Judge attribution, application outcomes, hearing and decision dates, catchwords, matter categories, legislation and authorities cited, counsel appearances, costs orders

Australian federal and state court decisions. The basis for decision statistics on about 2,000 Australian judicial officers.

Metrics derived: Decision counts, matter categories, citation counts, appellate records where linked

Application outcome rates

The share of classified published decisions in which the application was granted, partly granted or refused. A decision with no clear disposition is left unclassified and excluded from every rate, and the profile shows how many were excluded. Coverage levels by sample: very high (100+), high (50–99), medium (30–49), low (10–29). Rates on fewer than 10 matters are not shown. Every rate carries its count and 95% confidence interval.

Settlement & trial rates

Australian settlement rates come from the published record (settlement, discontinuance and consent orders in catchwords and orders). There is no Australian trial rate or party win rate: most settlements produce no judgment, and orders rarely name a winner.

Costs orders

Read from the orders of each NSW judgment: whether costs were awarded, and on what basis (ordinary, indemnity, no order). Measured on a held-out labelled set: 98.3% precision and 100% recall for the award, basis correct in every case. Shown per judgment; judge-level costs aggregates are withheld pending legal review.

Counsel and firm appearances

Read from the representation block of each NSW judgment, with side and seniority (SC, KC, QC) where stated. Matched on the published appearance name only. Self-represented parties are never recorded as counsel. Reported as counts of published judgments by court, side and judge. No counsel-level outcome rates are calculated or published.

Case duration & decision time

Australian decision time is hearing to judgment, where a hearing date is published. Each figure sits beside the court's own.

Citation influence

Citations of a judge's judgments by later decisions in the corpus, as a count and a percentile. Not adjusted for time on the bench or volume, so long-serving judges accumulate more. It describes citation frequency only. It is not a quality score or a ranking.

Procedural patterns (AI insights)

Written by a rule-based engine from the figures above. No external AI service is used. The wording describes historical patterns only: no advice, no predictions.
