Methodology & disclaimer
Firms and lawyers are ranked by the number of reported Supreme Court judgments they appear in, published on eLitigation. Counts reflect appearances in reported decisions only — unreported matters, settlements, and advisory work are not included. This is a descriptive count of activity by reported case volume, not an assessment of quality or standing, and not an endorsement or recommendation of any firm or lawyer. It is information, not legal advice.
