Appellate courts uphold far more rulings than they overturn, so lawyers who mostly defend rulings tend to show higher won-shares than lawyers who mostly challenge them. This breakdown lets you compare like with like.

Won means the court ruled the way this side asked. Mixed means the court agreed in part. Cases that were dismissed or have no clear result are listed but not counted. Based on the court's published decisions and unpublished orders; coverage is still being extended.
