In 412 Ninth Circuit decisions since 2015 reviewing summary judgment for the defendant in Title VII cases, the plaintiff obtained a reversal or partial reversal in 27%. Retaliation claims with a pretext dispute, like this one, did better: 34% (n = 96). Applying our calibrated model to the specific features of this case (retaliation theory, temporal proximity under 60 days, a disputed comparator, no direct evidence, published district opinion) gives an estimated reversal probability of 31% with an 80% interval of 22% – 41%.
Median time from notice of appeal to decision in the comparable set is 14 months (interquartile range 11 – 19). For settlement purposes: a one-in-three chance of returning to the district court, roughly 14 months out, against the defendant's cost of briefing and the risk of a published adverse precedent. The number that most changes the estimate is whether the panel treats the comparator as similarly situated; cases where the appellate court accepted the comparator reversed at 52%.
How often have comparable appeals succeeded, how long have they taken, where does this case sit within that record, and which features of the case move the estimate most.
| Criterion | Client case | Comparable set |
|---|---|---|
| Court | Ninth Circuit | Ninth Circuit |
| Claim | Title VII retaliation | Title VII (any theory): 412; retaliation with pretext dispute: 96 |
| Posture | Summary judgment for defendant | Same |
| Period | 2026 | Decisions 2015 – 2025 |
| Excluded | — | Pro se appeals, dismissals on procedural grounds, unpublished one-line affirmances without reasoning |

| Measure | Value | Basis |

A1. Model. Logistic regression of plaintiff reversal on coded case features (claim theory, evidence type, temporal proximity band, comparator status, opinion characteristics, year) trained on 3,140 Title VII summary-judgment appeals across all circuits with circuit fixed effects, 2015 – 2023, and validated on 2024 – 2025 decisions it had not seen.
Table A2. Held-out validation (2024 – 2025, n = 486).
| Measure | Value | Note |
|---|---|---|
| AUC | 0.71 | Moderate discrimination; appellate outcomes are noisy |
| Calibration slope | 0.96 | Predicted probabilities track observed rates |
| 80% interval coverage | 81% | Intervals are honest |
| Brier score vs. base rate | 0.176 vs. 0.196 | 10% improvement over "use the average" |
A3. Leakage audit. Features are restricted to those knowable at the time of the notice of appeal; outcome-derived language, panel identity and subsequent history are excluded. Temporal split validation guards against drift.
A4. Feature effects (odds ratios, client-relevant). Comparator accepted 2.4 (1.6 – 3.6); direct evidence 1.9 (1.3 – 2.8); temporal proximity < 60 days 1.3 (1.0 – 1.7); published district opinion 0.8 (0.6 – 1.0).
