The opinions were found by AI-assisted searches and sorted by AI. AI-assisted screening, then a primary-source audit by AI agents (all eight reversals, 12 random criminal opinions and 14 other opinions checked against the court’s own documents); no person has yet read every record, so the rest are screening-grade. Rows with only a few opinions show counts, not rates. What’s checked and what isn’t →
