Towards Explainable Adjudicative Variance: Quantifying Judicial Discretion via Gated Multi-Task Learning
Researchers propose a Judge-Aware Gated Multi-Task Learning architecture that disentangles objective case facts from adjudicative context to improve legal outcome prediction. The model uses a fine-grained outcome taxonomy and a gated fusion mechanism to dynamically modulate reliance on judge identity, evaluated on 13,937 UK Employment Tribunal decisions.
